SimRepo is a browser extension displaying similar GitHub repositories in the sidebar. This new major version introduces a completely rebuilt recommendation engine to discover relevant open-source tools on GitHub. Smarter embeddings, reduced popularity bias, and better handling of niche repositories.

Hey Product Hunt! 👋

When I first built SimRepo, the goal was simple: bring contextual project discovery directly into the GitHub sidebar via star-graph vector embeddings instead of superficial keyword matching.


While v1 worked well, it had two big flaws:

  1. It grouped tools using the same framework rather than those solving the same problem.

  2. Smaller projects had lower-quality recommendations.

Today, I'm rolling out the v2 recommendation engine, featuring a weighted co-occurrence matrix from carefully collected interactions on GitHub, now supporting more than 900k repositories, up from 450k on previous version. Instead of just telling you the results are better, you can test it yourself side-by-side against v1:

What SimRepo (still) does:

  • Directly in GitHub: Embeds a native "Similar Repositories" section into repo sidebars across Chromium browsers and Firefox.

  • Star-Graph Powered: Maps developer interaction patterns to connect projects that genuinely serve the same ecosystem and workflow.

Run your go-to repos through the side-by-side demo and let me know how the recommendations look to you. Feedback on edge cases and model output is very welcome!
