Frequently Asked Questions About Open-Source Rankings
Everything you need to know about how C-Rank™ benchmarks repository maintainer availability.
Are these open-source metrics and rankings 100% free to access?
Yes, completely free. GetMerged is built for the global developer and contributor community to make open-source contribution transparent and frictionless. You can browse, filter, inspect maintainer turnaround velocity, and track repository health without paywalls.
How does GetMerged help first-time open-source contributors?
We measure the First-Timer PR Acceptance Rate and scan for active beginner-friendly issues (good first issue, help wanted). This allows new contributors to identify projects where maintainers actively review and mentor external submissions rather than leaving PRs untouched.
Why should I use C-Rank™ instead of just sorting by GitHub stars?
GitHub stars reflect historical popularity rather than current maintainer availability. Many famous 50k+ star repositories suffer from maintainer burnout with massive unreviewed PR backlogs. C-Rank™ measures live reviewer responsiveness, external merge rates, and review turnaround times.
How many welcoming repositories do you index across different languages?
We actively evaluate over 1,400+ repositories across 20+ programming ecosystems. Our S-Tier (Super Welcoming) and A-Tier (Welcoming) catalog includes 350+ JavaScript & TypeScript projects, 280+ Python repos, 190+ Go tools, 120+ Rust systems, alongside high-velocity repositories in Java, C++, PHP, Kotlin, Swift, and more.
Does GetMerged track private code or require repository write access?
No. All metrics are calculated strictly from public GitHub events and public pull request activity without requesting code access or write permissions.
How are repositories evaluated in this directory?
Every repository is scored using our C-Rank™ algorithm. We track real maintainer PR response turnaround, external merge rates, first-timer acceptance rates, and active maintainer presence across thousands of GitHub projects.
What does the C-Rank™ tier (S, A, B, C, D) mean?
Tier S repositories are Super Welcoming with fast maintainer response (< 24h) and high merge rates. Tier A is Welcoming, Tier B is Active, Tier C is Selective, and Tier D indicates unmaintained backlogs or slow review times.
How often is data updated?
Our automated pipeline syncs daily from GitHub. Every repository page reflects the latest snapshot timestamp directly from GitHub.
Can I request my repository to be indexed or re-scored?
Yes! Submit your repository via our search bar on the homepage. If it is public on GitHub, it will be automatically queued and indexed in our daily evaluation cycle.
