A live heatmap of when r/indiehackers's top 100 posts of the past year were submitted. The brightest cells are the windows when this community engages most.
Analyze a different subredditr/indiehackers has a smaller but more engaged audience than the major startup subs, with international distribution that keeps activity steady across most UTC daytime hours (10:00-23:00 UTC). The audience is heavily oriented around the indie-hackers.com community, so posts that build on conversations happening there or reference shared community context perform unusually well. Weekend posts often outperform weekday ones because the audience treats the sub more like a hobby community.
Times above are UTC — the heatmap reflects the trailing 12 months of top posts, so it captures long-term patterns rather than this week's activity. Have questions about how this works? See the main tool page for FAQs.
