How are trending GitHub repositories ranked on GitHubRepo?

Repositories are ranked using an algorithmic velocity score combining 24-hour and 7-day star growth snapshots, fork acceleration, open issue resolution, and developer engagement telemetry.

How frequently are trending open source repositories updated?

Telemetry snapshots and rankings are recalculated continuously, with new daily leaderboards and video spotlight reels published on a strict 4-hour cycle.

How can developers promote their open source project?

Maintainers can claim their repository growth kit, embed live SVG star history badges in their README, or apply for spotlight video reels across YouTube, Instagram, Threads, and X.
