CompareGraph

Parses many cloned repositories into one local SQLite code graph and scores each clone against a feature taxonomy with cited verdicts.

What you can do

CompareGraph indexes cloned repositories into a single SQLite graph and compares them against a taxonomy pack (a family of features), producing a per-clone, per-feature verdict of has, partial or none with a citation to a file and line range. It exposes eighteen MCP tools over stdio, seventeen read-only and one write tool for recording claims, plus a matrix view of features against clones, ranked candidate mapping, and an Obsidian-style vault export. The engine is deterministic, runs entirely locally, and never calls a model.

When to use it

Useful when you have several repositories and one question: which of them has a given feature. Suited to teams comparing their product with the field, due diligence over a set of projects, or mapping an unfamiliar field, and to coding agents that need compact, citable facts about code rather than prose summaries.

Requirements

Runs as a local process on the user's machine (desktop only). One Rust binary; no runtime needed, though Node 18+ is required for the npm route and Rust 1.85+ to build from source. Installed via install script, npm, Homebrew, or cargo. No accounts, API keys, or environment variables are declared; settings use --root and COMPAREGRAPH_* variables. The engine makes no network call.
