We are a trend radar for open source.

// What we do

TrendingRepo is the trend desk for open source. We ingest signals from the active public sources every few hours, normalize them against per-category baselines, and rank repositories by cross-source agreement. The result is a live momentum index that catches breakouts hours before they hit the front page — and a deterministic score you can inspect, line by line, on every repo's detail page.

// Why we built it

Star counts are a lagging indicator. By the time a repository hits 10k stars, the operators who would have built on top of it have already moved on to the next thing. We wanted a surface that answered a sharper question: what crossed a meaningful threshold in the last 24 hours?

Single-source aggregators (Hacker News, ProductHunt, dev.to) each answer one slice of that question. We answer it across all of them at once, with anomaly detection that drops bot spikes and a category baseline that prevents “everything in AI is trending” distortion.

// The team

TrendingRepo is built and maintained by an independent founder team. The credentials behind the project: a decade of experience shipping production systems for ingestion pipelines, search infrastructure, and developer-facing APIs. We treat this site as a research tool first; the leadership commitment is to keep the front page free of paywalls and the API public.

// What we publish

• →A live momentum index across active data sources, refreshed every few hours.
• →A public REST API and a Portal v0.1 manifest exposing the same tools over JSON-RPC 2.0.
• →A zero-dependency CLI (Node 18+) for terminal use, and an MCP server for Claude or any agent.
• →An llms.txt index for AI crawlers, with a full variant covering the entire site map.
