Explore Tools
Browse by category, discover top-ranked tools, and compare side by side.
The Open Source Drop tracks open source tools across eight areas: AI and machine learning, web and frontend, infrastructure and DevOps, data and storage, developer tools, security and auth, observability, and self-hosted apps. Every tool carries a Score, our 0-100 report card across five dimensions: adoption, maintenance, community, license health, and our own analysis, so rankings reflect real signal rather than star counts. How scoring works.
