Hey Product Hunt! 👋

If you’re an open-source developer, you’ve probably seen endless profiles listing "contributions" that range from typo fixes in documentation to self-merged PRs on personal hobby repos.

When recruiters or community peers look at your stats, how do they know what's real?

We built OSS Proof to solve exactly that: a serverless, zero-database credentialing pipeline that proves the open-source code you actually ship.

How It Works ⚙️

Fetch: Automatically pulls every merged PR linked to your GitHub handle.
Filter: Strictly drops self-merges (if you merged it yourself into your own repo, it doesn’t count).
Score: Calculates a rigorous score (S to D grade) based on Impact (50%), Breadth (20%), Consistency (20%), and Trust (10%).
Certify: Commits a signed record directly via GitHub Actions—no external servers, no databases, purely trustless and transparent.

What You Get 🚀

A Verified Grade: From top-tier S to D, tough on purpose (ten PRs across ten projects beat thirty in one).
Profile Badges: Eight stunning SVG badge styles (Midnight, Aurora, Sunset, Terminal, and more) ready to drop straight into your README.md.
One-Click Verification: Anyone can click your badge to inspect your signed contribution record instantly.

It’s open source, built entirely on the GitHub API, and designed to give serious contributors the verifiable creds they deserve.
