How TrendingRepo Ranks Trending Repos (Momentum, Not Stars)

Raw GitHub star counts are a popularity museum: they tell you what was big, not what's moving. A repo with 80k stars that hasn't shipped in a year is less interesting than a three-week-old project firing on Hacker News, Reddit and X at once. So TrendingRepo ranks by momentum, not totals.

The momentum score

Every tracked repo gets a 0-100 momentum score that combines:

• Star velocity over 24h / 7d / 30d windows (not cumulative stars).
• Fork growth and contributor churn — real building, not just bookmarking.
• Commit freshness and release cadence — is it alive?
• Anti-spam dampening — star bursts with no follow-through get discounted.

On top of that we layer cross-source mention signals: when a repo is being discussed on Hacker News, Reddit, X, Bluesky, Product Hunt and Dev.to at the same time, that cross-platform confirmation is a far stronger signal than a spike on any single source.

Cross-source beats single-source

One feed is weak; five feeds agreeing is a real trend. A repo that's only trending on one platform is often noise — recycled content, a paid push, or a single viral thread. We weight cross-source agreement heavily and flag repos firing on three or more platforms as breakouts.

Where the rankings live

• The homepage and category leaderboards — the full ranked feeds.
• Curated best-of guides — editorial top picks per topic with a verdict.
• Head-to-head comparisons — two repos' stars, momentum and mentions side by side.

What we publish here

This blog covers what's actually breaking out and why: weekly movers, category deep-dives, and explainers on the protocols and tools showing up across the signal sources. The thesis is always the same — track momentum, read the cross-source evidence, and you'll see the winners before the star count catches up.
