- 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
| - Agents live in the same TypeScript DI app as your APIs, not as separate services
- Production-ready without cloud or Kubernetes dependency
- Complete operating system, not glue between frameworks
- Agents pause, resume, and survive restarts in production
- Developer-first with decorators and DI patterns developers already know
