How GetMerged Scores Repositories

Why Pull Requests Get Ignored (And How to Find Repos That Merge Yours)

Every day, developers clone a popular GitHub repository, read docs, write tests, and submit a clean pull request.

And then... silence. Weeks turn into months. The PR sits untouched until merge conflicts break it. GetMerged fixes this by measuring real maintainer activity before you write a single line of code.

60% Maintainer Burnout

Most open source maintainers work unpaid in their spare time. When popular projects get overwhelmed by issues, review queues slow to a crawl.

Stars Don't Mean Active

GitHub stars accumulate over years like museum plaques. A 40,000-star project might not have reviewed a community pull request in months.

Real GitHub review metrics

The 9 Signals We Check

Every repository is continuously benchmarked against other projects in the same programming language ecosystem.

01

External PR Acceptance Rate

Are outside submissions welcomed into main?

Measures whether non-maintainer community code actually reaches production. Filters out automated dependency bots and internal branch merges.

Primary Factor
02

Reviewer Response Turnaround

The 24-Hour Review Window

Calculates median hours before a maintainer leaves an actionable review. PRs that wait more than 7 days without feedback have an 80% higher abandonment rate.

Review Speed
03

Commit Rhythm & Recency

Active Maintainers vs. Stale Repos

Monitors commit activity across a rolling 180-day window, ensuring you don't spend time contributing to a project whose team stepped away.

Activity Recency
04

First-Timer Contributor Success

Do new authors receive constructive onboarding?

Tracks developers opening their very first pull request. Separates supportive, mentorship-driven teams from closed, unresponsive repos.

Beginner Friendly
05

Merge Speed & Cycle Duration

Fast turnaround without endless rebasing

Measures the time from initial opening to final merge, avoiding weeks-long cycles of unresolved merge conflicts and review stalling.

Merge Speed
06

Repeat Contributor Retention

Do contributors return for PR #2 and #3?

Checks if developers enjoy their first contribution experience enough to come back. The best indicator of welcoming, supportive maintainers.

Community Health
07

Review Cycle Efficiency

Clear guidance vs. fragmented nitpicks

Rewards teams that provide consolidated, clear review feedback in fewer rounds rather than dragging reviews out over weeks.

Review Quality
08

Active Review Team Breadth

Multiple active reviewers

Evaluates the number of active distinct reviewers. Projects with distributed review teams avoid single-maintainer bottlenecks and burnout.

Team Health
09

Issue & Discussion Response

Proactive issue triaging and scoping

Tracks how quickly maintainers respond to questions on issues and discussions to see if they actively help new contributors get started.

Responsiveness
