RepoCrunch

PyPI Python License: MIT

Analyze any public GitHub repository into structured JSON. No AI, no LLMs — fully deterministic.

Give it a repo, get back tech stack, dependencies, architecture, health metrics, and security signals in clean, consistent JSON. Use it as a Python library, CLI tool, REST API, or MCP server.

Quick Start

Requires Python 3.11+.

pip install repocrunch
repocrunch analyze fastapi/fastapi --pretty

That's it. Also works with uv:

uvx repocrunch analyze astral-sh/uv --pretty

Install from source

git clone https://github.com/kimwwk/repocrunch.git
cd repocrunch
uv venv && uv pip install -e ".[all]"

Install just what you need:

uv pip install -e "."          # Library only (httpx + pydantic)
uv pip install -e ".[cli]"     # + CLI
uv pip install -e ".[api]"     # + REST API
uv pip install -e ".[mcp]"     # + MCP server
uv pip install -e ".[all]"     # Everything

Set a GitHub Token (optional)

Without a token you get 60 API calls/hour. With one, 5,000/hour. A token also lets you analyze private repositories you have access to.

export GITHUB_TOKEN=ghp_...

Usage

CLI

repocrunch analyze fastapi/fastapi --pretty          # Full analysis, pretty JSON
repocrunch analyze facebook/react -f tech_stack       # Single field
repocrunch analyze https://github.com/gin-gonic/gin   # Full URL works too
repocrunch serve                                       # Start REST API on :8000
repocrunch mcp                                         # Start MCP server (STDIO)

Python Library

from repocrunch import analyze, analyze_sync

# Async
result = await analyze("fastapi/fastapi")

# Sync
result = analyze_sync("pallets/flask")

print(result.summary.stars)
print(result.tech_stack.framework)
print(result.model_dump_json(indent=2))

REST API

repocrunch serve

# Then:
curl "http://localhost:8000/analyze?repo=fastapi/fastapi" | python -m json.tool
curl "http://localhost:8000/health"
curl "http://localhost:8000/docs"    # OpenAPI docs

MCP Server (for Claude, Cursor, etc.)

repocrunch mcp    # Starts STDIO transport

What It Detects

Category

Signals

Summary

Stars, forks, watchers, age, license, languages

Tech Stack

Runtime, framework, package manager, direct/dev dependency count, key deps

Architecture

Monorepo, Docker, CI/CD platform, test framework

Health

Commit frequency (daily/weekly/monthly/sporadic/inactive), maintenance status, contributors, open issues

Security

.env file committed, Dependabot enabled, branch protection, SECURITY.md present

Roadmap

Not yet implemented, but planned:

  • Secrets regex scanning — detect leaked API keys, tokens, passwords in the file tree

  • Architecture type classification — library vs. application vs. framework

  • API rate limiting — per-key throttling for the REST API

  • npm/npx package — npx repocrunch analyze owner/repo

  • Vulnerability scanning — known CVE detection in dependencies

  • Comparison mode — side-by-side analysis of multiple repos

  • Historical tracking — track how a repo's health changes over time

  • Platform deployments — Apify Store, Smithery, mcp.so, RapidAPI

Already shipped: RepoCrunch is published on PyPI — pip install repocrunch.
