+- **[RAGFlow](https://github.com/infiniflow/ragflow)** (85k★) — one of the most popular open-source RAG engines; PDFOxide is the primary PDF engine in its `deepdoc` parsing pipeline ([go.mod](https://github.com/infiniflow/ragflow/blob/main/go.mod))
+- **[AFFiNE](https://github.com/toeverything/AFFiNE)** (70k★) — open-source Notion/Miro alternative; powers document extraction via AFFiNE's own [`doc_extractor`](https://crates.io/crates/doc_extractor) crate ([Cargo.toml](https://github.com/toeverything/AFFiNE/blob/canary/Cargo.toml))
+- **[grok-build](https://github.com/xai-org/grok-build)** (19k★) — xAI's coding-agent TUI; uses PDFOxide's rendering feature to read PDFs in a repo ([Cargo.toml](https://github.com/xai-org/grok-build/blob/main/Cargo.toml))
+- **[Xberg](https://github.com/xberg-io/xberg)** (formerly kreuzberg, 8.7k★) — polyglot document-intelligence framework; PDFOxide is its architectural PDF engine ([Cargo.toml](https://github.com/xberg-io/xberg/blob/main/Cargo.toml))
+- **[create-context-graph](https://github.com/neo4j-labs/create-context-graph)** (Neo4j Labs) — GraphRAG context-builder; PDFOxide is its primary PDF parser ([pyproject.toml](https://github.com/neo4j-labs/create-context-graph/blob/main/pyproject.toml))

 ## Why I built this
 
 I needed PyMuPDF's speed without its AGPL license, and I needed it in more than one language. Nothing existed that ticked all three boxes — fast, MIT, multi-language — so I wrote it. The Rust core is what does the real work; the bindings for Python, Go, JS/TS, C#, and WASM are thin shells around the same code, so a bug fix in one lands in all of them. It now passes 100% of the veraPDF + Mozilla pdf.js + DARPA SafeDocs test corpora (3,830 PDFs) on every platform I've tested.
