Hi HN! I'm excited to share ODocs with you today. I built it to solve a frustrating problem I kept encountering with AI coding assistants - they generate outdated or incompatible code because they have no idea about which framework versions your project is using or new versions and patches released.
How it works:
1. ODocs uses a CLI tool that provides latest version details of popular packages and also scans your project files (like package.json) to detect which frameworks and versions you're using.
2. It fetches the correct version-specific documentation from our open registry.
3. It runs a local server that AI coding assistants can connect to via API or MCP (Model Context Protocol).
4. When you ask for help, your AI assistant uses the right documentation for your exact versions.
Technical stack:
- Node.js CLI tool for framework detection
- Hono-based API server for documentation serving
- Local caching system to minimize network requests
- Open documentation registry (similar to Docker Hub model)
Current status: The initial prototype works with Hono 4.7.5 (a lightweight web framework). This targeted implementation proves the concept works, but we're just getting started.
What's next: We're focusing next on adding support for:
React ecosystem (React, Next.js)
TailwindCSS
Common Python frameworks
This is fully open-source, and we'd love contributions to expand framework support or improve the project!
Which frameworks would you most like to see supported next? Your feedback will help guide our priorities.
