Celmis

Most code tools read one repository at a time. Celmis indexes a set of them into one symbol graph, so a question can cross a boundary: ask which service still calls a function whose signature changed, and the answer comes back with file:line citations from a repository you never cloned. Same index, read many ways: PR review that sees cross-repo callers, dependency audit, CycloneDX SBOM, and an MCP server with 18 tools. Self-hosted, docker compose. Your model key, or Ollama locally. AGPL-3.0.
