Comparison

CodeGraph vs Serena

A like-for-like, spec-level comparison. Both entries are verified against their docs and repo.

CodeGraph

Pre-indexed, local code knowledge graph for agents.

  • + Local-first pre-indexed graph that auto-syncs on change
  • + Works across many coding agents out of the box
  • − Newer project with a smaller community
  • − Index must be maintained per repository

Serena

LSP-based semantic code tools for agents, as an MCP toolkit.

  • + Language-server-precise symbol and reference operations
  • + Agent-first, high-level abstractions over raw line-number tools
  • − Needs a language server per project
  • − Heavier to set up than plain search
