ColdBox Hierarchical MVC is the de-facto enterprise-level HMVC framework for the BoxLang JVM language and the ColdFusion (CFML) language. It's professionally backed, conventions-based, modular, highly extensible, and productive. Getting started with ColdBox is quick and painless. ColdBox takes the pain out of development by giving you a standardized methodology for modern web development with features such as:
- Conventions instead of configuration
- Modern routing engine
- RESTFul API ready
- A hierarchical approach to MVC using ColdBox Modules
- Event-driven programming
- Async and Parallel programming constructs
- Integration & Unit Testing
- Included dependency injection
- Caching engine and API
- Logging engine
- An extensive ecosystem
- Much More
It provides a set of reusable code and tools that can be used to increase your development productivity, as well as a development standard for working in team environments.
| 🧭 Conventions over Configuration | Predictable folder structure and naming so you spend time on features, not scaffolding | conventions.md |
| 🚏 Modern Routing DSL | A fluent router for resources, groups, middleware, route-level caching, and more | README.md |
| 🤖 AI-Native Routing | First-class toAi(), toMCP(), and toAiGateway() terminators for
building agentic APIs |
ai-routing.md |
| 📡 Real-Time Streaming | Server-Sent Events as a first-class citizen, with a fluent emitter API | server-sent-events.md |
| 🧩 HMVC Modules | Build self-contained, reusable application modules with their own routes, models, and views | README.md |
| 🔌 RESTful APIs | Content negotiation, structured responses, and a dedicated REST handler base class | rest-handler.md |
| 🎯 Event-Driven Interceptors | Hook into the framework lifecycle or announce your own custom events | README.md |
| ⚡ Async & Parallel Programming | Futures, schedulers, and parallel collection operations out of the box | README.md |
| 🧪 Integration & Unit Testing | TestBox-powered testing baked into every generated application | README.md |
ColdBox is built for the agentic era. Beyond toAi()/toMCP()/toAiGateway() routing above, the platform ships:
| 🤖 Agentic ColdBox | A full AI development toolkit built into the coldbox-cli: guidelines, a 200+ skill registry,
multi-agent support (Claude, Copilot, Cursor, Codex, Gemini, and more), and 30+ built-in MCP documentation
servers |
agentic-coldbox.md |
| 🔌 cbMCP | Live application introspection over MCP, so an AI agent can query your running app in real time (🚀 BoxLang only) | coldbox-mcp-server.md |
| 💬 Conversational Context | Automatic userId/conversationId/threadId threading on
toAi() routes for multi-turn agents |
ai-routing.md |
| 🚪 AI Gateway Routing | Mount a BoxLang AI Gateway (Slack, Telegram, WhatsApp, or a signed webhook) directly on a route | ai-gateway-routing.md |
Look for the 🚀 BoxLang Exclusive badge throughout these docs to spot features only available on the BoxLang runtime.
BoxLang is a modern dynamic JVM language developed by the ColdBox team that can be deployed on multiple runtimes: operating system (Windows/Mac/*nix/Embedded), web server, lambda, iOS, android, web assembly, and more. BoxLang combines many features from different programming languages, including Java, CFML, Python, Ruby, Go, and PHP, to provide developers with a modern, functional and expressive syntax.
ColdBox has been designed to work in both BoxLang and CFML language engines. However, it is extremely optimized for BoxLang, since it is the same team that develops the language and the framework.
