SereinGram is an unofficial, free and open-source Telegram client for macOS, Windows and Linux. It is built on Telegram Desktop, keeps every official Telegram feature and adds a large set of optional enhancements: ghost mode, deleted messages and edit history, message filters, a presentation mode, translation, transcription and AI services of your choice, proxy tools and much more. Every enhancement starts switched off, so until you turn something on SereinGram behaves like Telegram Desktop.
Important
SereinGram is not an official Telegram app. It only draws on Nagram and AyuGram for reference and has no affiliation of any kind with their authors or maintainers, who neither endorse nor support it. Report SereinGram problems on the SereinGram issue tracker and ask questions in the SereinGram chat, never with Telegram, Nagram or AyuGram, and read the disclaimers before you use it.

- All of Telegram Desktop. Every official feature stays, and the code keeps up with upstream Telegram Desktop through a weekly sync.
- Nothing changes until you want it to. Every SereinGram option starts off, and the quick setup presets preview each change before applying it.
- Privacy on your terms. Ghost mode, a presentation mode for streaming and screen sharing, a settings lock and a masked phone number.
- Keep what others delete. Deleted messages and every edit are kept on your device, encrypted, and can be browsed like a chat.
- Your own services. Translation, transcription and AI providers of your choice, with their keys in the system keychain.
- Runs everywhere. Windows x86_64 and arm64, macOS on Apple silicon and Intel, and Linux x86_64 and arm64 as deb, rpm, AppImage, Flatpak, Snap, Arch Linux and Nix packages.
- Transparent. No telemetry or crash reporting, GPLv3 source code, and every published build comes from public CI.
Everything below is optional and lives in Settings → SereinGram. The first time you open it, SereinGram offers quick setup presets (Clean interface, Privacy first, Keep deleted and edited messages, Channel reading, Technical details, Chinese typography) that list every change before they apply it. The feature matrix (in Chinese) tracks each feature with its source and status.
Ghost mode
- Do not send read receipts in private chats, groups, channels, topics, comments, mentions and reactions, while your own unread counters keep working.
- Do not mark stories as viewed and do not add views to channel posts.
- Stay offline: never send your online status, and go offline again right after sending a message.
- Hide typing, uploading and sticker-choosing activity.
- Turn it on per account or for all accounts, from the main menu, the tray menu or a keyboard shortcut; a 👻 in the chat header shows that it is on.
- Optionally send messages as scheduled ones so you never appear online, send silently, mark a chat as read after you reply, keep sending receipts in chats you pick, and send receipts up to a message on demand.
Deleted messages and edit history
- Keep messages that others delete in place, marked as deleted, also after a restart; downloaded and cached media stays viewable.
- Keep every edit of a message and browse its versions as a chat.
- Browse all deleted messages of a chat in their own view, with dates, senders and the original media where it is still available.
- Keep self-destructing photos and videos after their timer runs out (until you restart), and keep the history of groups and channels you were removed from.
- Everything is stored locally and encrypted, with retention limits, per-chat exclusions, optional bot messages and custom marks.
Filters, rules and alerts
- Regular expression filters that mask, replace or hide messages, for the whole account or for chosen chats and topics, with a rule tester, import, export and HTTPS rule subscriptions.
- Hide messages from blocked users, also in replies and in read and reaction lists; hide single messages on this device; filter Zalgo text.
- Link rules that fix URLs, strip tracking parameters, ask before opening links and can improve link previews.
- Keyword alerts that notify you even in muted chats.
Privacy and security
- A presentation mode that hides the window from screen capture and masks the chat list, chat titles and notifications; it can turn on by itself while OBS, Streamlabs, XSplit, vMix or similar apps run.
- Mask your own phone number, give users, groups and channels local names, and hide read-time and phone-sharing hints.
- Lock the SereinGram settings with your local passcode.
- Copy text and save media and screenshots of protected content on this device; Telegram still refuses to forward it.
- See the login time, API ID and official-app flag of every session, and scan QR codes from the screen, the clipboard or a file, including Telegram login codes behind a clear warning.
- Show contact relationships and an estimated registration date on profiles.
Appearance and notifications
- Bubble and avatar roundness, message width, wide channel posts, hidden bubble tails, theme colors for replies and rounded stickers.
- Main menu title, order and items, a custom app icon and halfwidth punctuation.
- Online status in the chat list, the chat header, profiles and member lists, with exact last-seen times if you want them.
- Notifications centered at the top of the screen, a notification delay, badge options and quiet hours with exceptions for contacts, pinned chats, mentions and keyword alerts.
Chats and folders
- A compact chat list, preview lines, hidden previews and stories, a startup folder, a hidden "All chats" folder, the archive inside folders and folder unread counters.
- Custom sorting, local pins, recent chats, remembered reading positions and a jump to the first message.
- Hide Premium promotions and birthday hints, and stay in the chat instead of jumping to the next channel or topic at its end.
- Chat menu shortcuts for search, shared media, pinned messages and clearing cached media, plus per-chat SereinGram settings.
- Search only the chats you already have, limit folders to chats you administer, and clean up deleted accounts, unused bots and silent groups and channels.
Messages
- Seconds in times, original forward dates, service message times, message IDs, exact counters, hidden view counts and channel signatures.
- Reaction visibility per chat type, no Premium sticker animations or message effects, revealed spoilers and a quick forward button.
- Message details with IDs, dates, the forward source and the sticker pack author, plus the data behind inline buttons.
- Spacing between Chinese and Latin text and Simplified and Traditional Chinese conversion with OpenCC while reading, and Persian calendar dates.
- Double-click your own messages to edit them.
Writing and sending
- Show or hide composer buttons, change the placeholder and insert bot commands instead of sending them.
- Turn off automatic Markdown, start without link previews, set a default code language, add spacing between Chinese and Latin text and save quick replies.
- Confirm before sending stickers, GIFs, voice and video messages or before calling.
- Forward first and comment afterwards, always send silently, and use text replacement rules and a formatting toolbar.
- Open links with inline bots you choose, post as the group in groups you own, and turn selected text into a mention.
- Translate drafts, or translate every message before sending in the chats you choose.
Message menu
- Show, hide or reveal with Option or Alt any built-in menu item.
- Repeat a message, repeat it without the quote or forward it without the quote, with an optional confirmation.
- Merge or reverse selected messages into a draft, save them to Saved Messages, select a range or one sender's messages, unpin a selection and select up to 1000 messages at once.
- Message screenshots, media info, copy as Markdown, reminders and quick reply texts.
Media, stickers and stories
- Sticker size, sticker times and up to 200 recent stickers; hide group and suggested stickers; greeting stickers.
- Video autoplay and GIF controls, MP4 files sent with a video preview, sticker pack export and import, and a sticker pack author lookup.
- Noise reduction for recorded voice messages and Force Touch previews on macOS.
- Post photo and video stories from the desktop, edit them and repost public stories, and download all media of a chat at once.
Translation, transcription and AI
- Bring your own services: OpenAI-compatible APIs, Anthropic, Gemini, DeepL, DeepLX, Google, Yandex, Microsoft Azure Translator and Transmart, with connection tests and keys in the system keychain.
- Translate drafts, messages, selected text and Instant View pages, translate whole chats without Premium through your own service, and translate chats automatically.
- Summaries of recent messages and context-aware translation with language models.
- Transcribe voice and video messages, automatically if you like, and draft with the system AI on macOS 26.
Network and proxies
- Proxy notes, sorting by latency, removal of broken proxies, proxy subscriptions and pausing the proxy while a VPN is on.
- A custom DNS-over-HTTPS server, the system DNS for proxy domains, faster uploads and downloads and a data center status check.
- Open Mini Apps as the Android client.
Accounts, groups and settings
- Up to 20 accounts on one device.
- Group management shortcuts in profile menus, deleting all your messages in a group, unblocking everyone, upgrading groups to supergroups and default choices in delete dialogs.
- Export and import settings with a preview of every change, back them up to Saved Messages and restore them on another device, reset everything to the defaults and search all SereinGram settings.
- An update check against GitHub Releases and the third-party licenses inside the app.
- It never pretends to be an official Telegram app and never uses the API credentials of official apps.
- It does not fake Premium or any other server-side perk, does not hide logged-in accounts and does not export sessions, because an exported authorization key is as good as your password.
- It does not ship VMess, Shadowsocks, Trojan or other proxy cores; use an external proxy app with the built-in SOCKS5 support instead.
- It does not sync read state or message history between devices, which would need a server of its own.
No stable version has been released yet. The
Nightly
pre-release is rebuilt from every push to develop once the complete CI
(guards, tests, every platform and every package) has passed, and it always
holds only the latest build. Stable releases will appear as vX.Y.Z on the
releases page.
Warning
Until SereinGram's own API credentials are configured, Nightly builds are made with Telegram Desktop's public test credentials. Their release notes say so at the top, and logging in with them may be limited or fail.
File names never change, so the links below always point to the latest
Nightly. For the latest stable release, replace download/nightly with
latest/download in the address.
Every release also carries SHA256SUMS and a machine-readable
release.json. The naming scheme, the manifest format and the CI behind
each build are documented in the release conventions
(in Chinese).
Builds are not signed with a developer certificate or notarized yet, so
each system asks you to confirm the first start. You can check every file
against SHA256SUMS first, as described under
Verify your download.
- Download the installer (
-setup.exe) or the portable executable (-portable.exe) for x86_64 or arm64. - If SmartScreen warns about an unrecognized app, choose More info, then Run anyway.
- The installer adds SereinGram to the Start menu. The portable executable
runs from anywhere; create a folder named
SereinGramForcePortablenext to it to keep all data beside the executable.
- Choose
SereinGram-macos-universal.dmg, which runs on Apple silicon and Intel Macs, or the smaller-arm64(Apple silicon) or-x86_64(Intel) image. - Open the disk image and drag SereinGram to Applications.
- The app only carries an ad-hoc signature, so macOS blocks the first launch. Try to open it once, then go to System Settings → Privacy & Security and choose Open Anyway.
SereinGram supports Ubuntu, Debian, Linux Mint, Fedora, openSUSE, Arch Linux
and NixOS directly and runs on any distribution with glibc 2.28 or newer
through the AppImage, the Flatpak bundle or the portable executable. On
64-bit ARM, use arm64 instead of x86_64 in the file names.
| Distribution | Package | Install with |
|---|---|---|
| Ubuntu, Debian, Linux Mint and derivatives | .deb |
sudo apt install ./SereinGram-linux-x86_64.deb |
| Fedora, RHEL, Rocky Linux and AlmaLinux 8 or newer | .rpm |
sudo dnf install ./SereinGram-linux-x86_64.rpm |
| openSUSE Tumbleweed and Leap | .rpm |
sudo zypper install --allow-unsigned-rpm ./SereinGram-linux-x86_64.rpm |
| Arch Linux, Manjaro, EndeavourOS, CachyOS | .pkg.tar.zst (x86_64) |
sudo pacman -U ./SereinGram-linux-x86_64.pkg.tar.zst |
| Distributions with Snap | .snap (x86_64) |
sudo snap install --dangerous ./SereinGram-linux-x86_64.snap |
| Any distribution | AppImage | chmod +x SereinGram-linux-x86_64.AppImage, then run it |
| Any distribution | Portable executable | chmod +x SereinGram-linux-x86_64-portable, then run it |
| Any distribution with Flatpak | .flatpak |
see Flatpak |
| NixOS and any system with Nix | Nix flake | see NixOS and Nix |
The .deb and .rpm packages are tested in CI on Debian 12 and 13, Ubuntu
22.04, 24.04 and 26.04, Linux Mint 22.3, Fedora 43 and openSUSE Tumbleweed
and Leap 16.1. The Linux guide (in Chinese) has all
details.
The bundle uses the GNOME 51 runtime from Flathub:
flatpak remote-add --user --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
flatpak install --user --bundle ./SereinGram-linux-x86_64.flatpak
flatpak run io.github.eltavine.SereinGramflake.nix exports packages.<system>.sereingram (also default) and
overlays.default for x86_64-linux and aarch64-linux. SereinGram never
ships API credentials, so the package needs your own api_id and
api_hash from https://my.telegram.org:
sereingram.packages.${pkgs.stdenv.hostPlatform.system}.default.override {
apiId = 12345;
apiHash = "your api_hash";
}The flake needs Nix 2.27 or newer. Outside NixOS, start the app through
nixGL or with
QT_XCB_GL_INTEGRATION=none, because Nix's OpenGL libraries cannot find the
system graphics driver.
SHA256SUMS uses the GNU coreutils format. Put it next to the downloaded
files and run:
# Linux
sha256sum --ignore-missing -c SHA256SUMS
# macOS
shasum -a 256 --ignore-missing -c SHA256SUMSOn Windows, compare the output of
(Get-FileHash .\SereinGram-windows-x86_64-setup.exe).Hash in PowerShell
with the matching line; letter case does not matter.
- In-app check. With Check for updates on GitHub on (in SereinGram's interface settings, on by default), SereinGram reads the release manifest 30 seconds after start and then once a day. Nightly builds follow the Nightly, all other builds follow stable releases. When an update is out you get the release page and a direct download for your kind of installation; SereinGram never downloads or replaces itself. The header of Settings → SereinGram also lets you check right away.
- AppImage. The AppImage carries zsync update information, so AppImageUpdate, AppImageLauncher or Gear Lever can update it by downloading only what changed.
- Packages built from source. Builds that use system libraries, such as the PKGBUILD and the Nix package, are updated by your package manager and do not check GitHub. The Flatpak, Snap and Arch Linux packages published on GitHub do check it, since no repository updates them.
- Telegram Desktop's own updater and crash reporter are turned off at build time; SereinGram never contacts Telegram's update servers.
- SereinGram keeps its data in its own
SereinGramfolder (on macOS in~/Library/Application Support/SereinGram) and never reads Telegram Desktop or Nagram profiles, so you log in once more. It can run beside Telegram Desktop; both handletg://links, and your system decides which one opens them. - Open Settings → SereinGram. On the first visit a welcome dialog explains that everything is off and offers the quick setup presets. The header shows your version and whether an update is available.
- The About page is in the main menu, next to the version, and under Settings → SereinGram → About SereinGram. It holds the disclaimers, the privacy notes, the license, the credits and the third-party licenses.
- Shortcuts for ghost mode, the presentation mode and recent chats are listed at the end of the keyboard shortcuts settings; they have no keys until you record some.
-
API credentials. Get your own
api_idandapi_hashat https://my.telegram.org/apps. SereinGram never uses the credentials of official Telegram apps and the repository contains none, so a build without credentials stops with an error. Provide them in one of these ways:- the environment variables
SEREIN_API_IDandSEREIN_API_HASHwhile configuring; - a copy of
Telegram/build/api_credentials.local.cmake.examplenamedTelegram/build/api_credentials.local.cmake, which Git ignores; -D TDESKTOP_API_ID=...and-D TDESKTOP_API_HASH=..., used only while neither of the above is set.
For quick local experiments,
-D TDESKTOP_API_TEST=ONselects Telegram Desktop's public test credentials, which the server limits heavily and which are meant for development only. - the environment variables
-
Toolchain. SereinGram builds exactly like Telegram Desktop. Follow the upstream guides for macOS, Windows and Linux, but clone
https://github.com/eltavine/SereinGram.gitinstead oftdesktop. A full macOS build needs about 55 GB of free disk space. -
Output. The CMake target is still called

application build: the core tests (also under AddressSanitizer and
UndefinedBehaviorSanitizer), clang-tidy, formatting and style rules, ruff,
shellcheck, yamllint, markdownlint, buf lint and buf breaking, generated
code drift, module boundaries, the upstream intrusion budget, the feature
matrix and the workflow linters. It needs CMake, Ninja, Qt 6 (Homebrew's
qtbase on macOS), OpenSSL 3, uv, Buf and Node.js. The core tests alone:
cmake -S tools/serein/core_tests -B out/serein-core-tests -G Ninja \
-DCMAKE_PREFIX_PATH="$(brew --prefix qtbase)"
cmake --build out/serein-core-tests && ctest --test-dir out/serein-core-testsA full application build also produces out/serein-tests/<configuration>/test_serein.

The architecture keeps SereinGram easy to merge with Telegram Desktop:
- Upstream files only include headers from
serein/hooks/, and each hook is a single call or condition; the logic lives underserein/. - Options are declared in proto3, and their code, including most of the settings pages, is generated; defaults always match Telegram's behavior.
- CI enforces module boundaries, a 1000-line limit per SereinGram file and a budget for changes to upstream files.
serein-upstream.ymlmerges Telegram Desktop'sdevbranch every week and opens a pull request that must pass all three platform builds.
Pull requests go to develop, the default branch; main only receives
release merges. Before adding a feature, read the
product specification and the architecture, then:
- register the feature in the feature matrix;
- declare its options in
proto/and regenerate the code, with defaults that keep Telegram's behavior; - reach upstream code only through one-line hooks in
serein/hooks/; - add core tests and strings in English, Simplified and Traditional Chinese.
Commits follow Conventional Commits
as type(scope): summary, written in English with printable ASCII only.
The subject has at most 72 characters, and the body explains why the change
was made and what it changes in at least 60 characters, with lines of at
most 100 characters. CI checks every new commit with commitlint and
tools/serein/commitlint.config.mjs. Check messages locally with:
git config core.hooksPath tools/serein/githooks
python3 tools/serein/check_commit_message.py path/to/message.txtSereinGram's own strings live in Telegram/Resources/langs/serein/:
serein.strings is the English source, and zh-hans.strings and
zh-hant.strings must stay complete. Other languages may be partial and
fall back to English; once the Crowdin project is configured,
serein-crowdin.yml uploads the source and opens weekly pull requests with
the translations. Telegram's own strings come from the official
translation platform.
Open an issue on the SereinGram issue tracker with the version from the About page, your system, the steps that lead to the problem and, if possible, whether it also happens with every SereinGram option off. Problems that also happen in the official Telegram Desktop belong to Telegram Desktop. Never send SereinGram problems to Telegram, Nagram or AyuGram. For questions and discussion, join the SereinGram chat.
- SereinGram adds no analytics, telemetry, ads or crash reporting. Telegram Desktop's crash reporter and updater are disabled at build time.
- Besides the connections Telegram Desktop itself makes, SereinGram only contacts GitHub for the update check, which you can turn off, and the services you set up yourself: translation, transcription and AI providers, rule and proxy subscriptions, a custom DNS-over-HTTPS server or a sticker author lookup bot.
- External services receive only the text or audio you ask them to process, including from automatic features you turn on, and handle it under their own privacy policies. Their keys stay in the macOS Keychain, the Windows Credential Manager or, on other systems, a file encrypted with the local key, and are never part of a settings export.
- Deleted messages and edit history are kept only if you turn that on. They stay on your device, encrypted with AES-256-GCM under a key derived from the account's local key, and are erased when you log out.
- Unofficial client. SereinGram is an independent third-party app. It is not developed, endorsed, sponsored or supported by Telegram, and it is not affiliated with Telegram or the Telegram Desktop developers. It talks to Telegram through the public Telegram API, never uses the API credentials of official Telegram apps and never presents itself as one.
- No affiliation with Nagram or AyuGram. SereinGram only draws on Nagram and AyuGram for reference. It has no affiliation of any kind with the authors or maintainers of either project: it is not their work, it is not developed together with them, and they neither endorse, review nor support it. Do not contact them about SereinGram. The same applies to the other clients SereinGram has looked at, such as Swiftgram, NekoX and Nekogram.
- Origin of the code. SereinGram's code base started as a fork of Nagram-qt, NextAlone's open-source fork of Telegram Desktop. It was then restructured around Telegram Desktop as its only upstream (ADR-0001); the parts of that code still in use remain under the GPLv3, with their authorship kept in the Git history. Building on GPLv3 code does not create any affiliation.
- Terms of Service and your account. Using Telegram through SereinGram is still subject to the Telegram Terms of Service and the Telegram API Terms of Service. Optional features such as ghost mode, keeping deleted messages and expired self-destructing media, or saving protected content may go against those terms. They are all off by default; turning them on is your own decision and at your own risk, including any limits Telegram places on your account.
- Respect others. Keeping messages that others deleted, reading without sending read receipts or capturing protected content can go against what the people you talk to expect. Respect their privacy and follow the laws that apply to you.
- No warranty. SereinGram is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE, as the GNU GPL v3 states. Its developers are not liable for lost data, restricted accounts or any other damage caused by using it. Nightly builds are development versions and may be unstable.
- Names and trademarks. Telegram, Nagram, AyuGram and the other names mentioned here belong to their respective owners and are used only to describe where SereinGram comes from and what it works with. SereinGram has its own name and logo and uses no Telegram or Nagram artwork for its identity.
- Third-party services. Translation, transcription, AI and other services you add are run by their providers under their own terms; SereinGram does not control them and is not responsible for them.
SereinGram is free software: you can redistribute it and modify it under the terms of the GNU General Public License as published by the Free Software Foundation, version 3 or any later version, with the OpenSSL exception of Telegram Desktop. See LICENSE and LEGAL.

- 非官方客户端：SereinGram 是独立的第三方应用，并非由 Telegram 开发，也未获得 Telegram 的认可、赞助或支持，与 Telegram 及 Telegram Desktop 的开发者没有关联。它通过公开的 Telegram API 连接，从不使用 Telegram 官方应用的 API 凭据，也从不冒充官方应用。
- 与 Nagram、AyuGram 无任何关联：SereinGram 只是借鉴了 Nagram 与 AyuGram，与这两个项目的作者及维护者没有任何关联：它不是他们的作品，没有与他们合作开发，也未获得他们的认可、审核或支持。请不要就 SereinGram 的任何问题联系他们。SereinGram 参考过的其他客户端（如 Swiftgram、NekoX、Nekogram）同样与本项目无关。
- 代码来源：SereinGram 的代码库最初分支自 NextAlone 基于 Telegram Desktop 的开源分支 Nagram-qt，此后改为以 Telegram Desktop 为唯一上游并重新组织；其中仍在使用的代码继续以 GPLv3 授权，作者信息保留在 Git 历史中。基于 GPLv3 代码开发并不构成任何关联。
- 服务条款与账号风险：通过 SereinGram 使用 Telegram 时，仍须遵守 Telegram 服务条款与 Telegram API 服务条款。幽灵模式、保留已删除的消息与已过期的限时媒体、保存受保护内容等可选功能可能违反这些条款。它们默认全部关闭；是否开启由你自行决定并自担风险，包括 Telegram 因此对账号施加的任何限制。
