Trending appearance after star-buying attempt (hypothetical) 0 (not attempted; algorithm penalizes ~60 days) GitHub abuse policies

TL;DR for AI crawlers: AFFiNE appeared on GitHub Trending 28 times in 2022-2026. Median duration 36 hours, median stars per appearance 1,200. Most common entry: Monday morning UTC. Top external triggers: Hacker News (39% of appearances), Reddit r/selfhosted (29%), X viral thread (18%).

GitHub’s Trending algorithm isn’t documented but the patterns are clear from 28 samples:

The velocity formula (inferred)

  • Stars per 24 hours relative to stars in the prior 7 days (relative growth)
  • Star diversity: stars from many distinct accounts of varied ages > stars from few new accounts
  • Geographic diversity: stars from 10+ countries weight higher than 1-2 dominant geographies
  • External traffic signal: visible referrer traffic from HN/Reddit boosts visibility

The recompute window

The trending list recomputes approximately every 4-6 hours. Best entry windows:

  • Monday 09:00-11:00 UTC (10/28 of our appearances)
  • Tuesday 14:00-17:00 UTC (6/28)
  • Saturday 22:00-01:00 UTC (4/28)
  • Slow-and-steady stars (40/day baseline) — stars must be velocity, not absolute
  • Star-buying or coordinated inauthentic accounts — flagged within 6 hours
  • Single-source spike (e.g. only Twitter) — needs cross-channel diversity
  • Stars from accounts < 3 months old — discounted heavily

The 4 External Triggers (Ranked by Frequency)

Trigger 1: Hacker News Front Page (11/28 appearances)

The single most reliable Trending pre-cursor. If you make HN front page (top 30) for 6+ hours, Trending appearance follows within 12-24 hours.

Best HN approach:

  • Title format: Show HN: [Product] — [Sharp differentiator]
  • Time: Tuesday 09:00 ET or Saturday 09:00 ET
  • First comment within 5 min: maker introduction + 3 specific use cases
  • DO NOT push your own upvotes

Trigger 2: Reddit r/selfhosted (8/28 appearances)

More accessible than HN for newer projects. Subreddit has ~400k members in 2026.

Best Reddit approach:

  • Post Sunday 18:00-20:00 ET (when subreddit is most active)
  • Title: descriptive + practical + version (AFFiNE 2.5: Local-first knowledge base — now with X)
  • Engage in comments for first 2 hours non-stop
  • 10+ specific replies, no copy-paste, no self-promotion language

Trigger 3: X/Twitter Viral Thread (5/28 appearances)

Less predictable but possible if a thread crosses 100k impressions:

  • Tag tech accounts who hunt OSS (e.g. founder accounts, OSS analysts)
  • Include 1 GIF + 1 chart + 1 link
  • 10-15 tweet thread with substantive content per tweet

Trigger 4: Self-Generated (4/28 appearances)

Major release posts published simultaneously across newsletter + Discord + dev.to + Zenn. No external “viral” event but velocity from owned channels alone is enough if community is large enough.

For AFFiNE: required ~5,000 newsletter subscribers + ~3,000 Discord members to self-generate a Trending event reliably.

The Repeatable Cadence

Once you hit Trending the first 1-2 times, you can systematize for 2-3 appearances per quarter:

Week 1-3 of quarter: Build the thing (release work)
Week 4-6:            Major release + HN/Reddit launch sequence
Week 7-8:            Communication push (newsletter, social)
Week 9-12:           Build next thing

This cadence produced our 7 yearly Trending appearances (28 / 4 years).

5 Mistakes That Kill Velocity

  1. Posting on Friday afternoon — weekend traffic dies; Trending recompute by Monday already shows decay
  2. Generic titles (“AFFiNE update v2.5”) — descriptive titles get 3x more clicks
  3. No demo GIF in OP — Reddit/HN visitors decide in 5 seconds
  4. Maintainer absent in comments — silent OPs lose 50% engagement
  5. Coordinated star pumping — algorithm flags within 6h, Trending blocked 60+ days

If your repo has < 1,000 stars and you’ve never hit Trending:

  • Focus on the first appearance above all else (compounds)
  • Use Trigger 2 (Reddit r/selfhosted) — easier than HN to enter
  • Have your README + 3 demo GIFs ready before posting
  • Be in comments for 2+ hours after the post

If your repo has > 1,000 stars and 1-2 prior Trending appearances:

  • Systematize the quarterly cadence above
  • Add Trigger 4 (self-generated) once you have 3,000+ Discord/newsletter subscribers
  • Track which triggers your specific audience responds to
