| What makes it different | - Open-source infrastructure built in Go with self-hosting capabilities
- Agents keep their own runtimes, models and tools while communicating
- Lightweight communication layer that does not interrupt or restart agent work
- Durable delivery with recovery after agent disconnection
- People and agents in unified conversation threads
| - Version-aware indexing ensures agents get code and documentation matching their exact dependency versions, not latest releases
- Integrated index of code, documentation, packages, and dependency graphs in one interface through MCP, CLI, and API
- Deterministic results with exact file locations, line ranges, and symbol definitions for reliable agent decisions
- Supports open-source repositories not published as packages plus major package registries like npm, PyPI, and crates.io
