Registry lookups,
without the wait.
Built out of frustration with slow, multi-click searches on official registries. OSMA uses frozen snapshots to deliver instant version numbers and search results—no Fastly delays.
Currently indexing a massive, instantly searchable archive of millions of NPM packages and hundreds of thousands of PyPI projects.
Why I built OSMA
This project started because I was spending too much time hunting for package details. Browsing NPM and PyPI often meant waiting for Fastly security checks and clicking through 2 or 3 pages just to verify a simple version number.
To fix this, I downloaded complete snapshots of both registries at a specific point in time. Now, we can query package lists and version numbers instantly with zero wait.
About the Archives
OSMA queries a static dataset to skip live registry bottlenecks during search.
