Launch Day Forecaster (Product Hunt)

Estimate Product Hunt upvote velocity and top-3 / top-1 probability for your launch slot.

Your Product Hunt launch slot

Based on publicly observed PH leaderboard patterns — category baselines, day/hour multipliers, and supporter contribution.

Product Hunt resets at 12:01 AM PT — launching at midnight gives you the full 24 hours.

People you can notify on launch day.

How the forecast works

The forecast multiplies a category-level baseline (publicly observed top-1 upvote totals) by day-of-week multipliers, hour-of-day multipliers (derived from PH leaderboard observation), prior activity weight, and a capped supporter-list multiplier. No competitors build this for free.

Output is illustrative — not a guarantee. The model has no access to real-time PH data or your maker profile.

Best launch practices

  • → Launch at 12:01 AM PT Tuesday or Wednesday — most active days by upvote volume.
  • → Pre-warm your mailing list — email supporters the evening before.
  • → Comment actively on other launches in the days before — builds your maker standing.
  • → AI and Dev Tools categories consistently produce the highest vote counts in 2024–25.
