AtlasRepo Open Source Catalog

Evidence-backed open-source search for coding agents.

Documentation · Hosted MCP · npm · Skills

A living, auto-curated catalog of open-source projects, enriched with practical summaries, categories, quality signals and transparent scoring.

This repository turns a fast-moving open-source ecosystem into a browsable and machine-readable decision layer. Use it to discover candidates, compare practical fit and give coding agents grounded starting points before deeper technical, security and license review.
