A live heatmap of when r/SaaS'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/SaaS posts that hit the top of the feed tend to cluster around weekday US business hours (15:00-21:00 UTC) when founders are taking breaks and scrolling. Weekend traffic is meaningfully lower, but weekend posts often face less competition — a quality post on Sunday morning UTC can ride a slower feed longer than the same post on Tuesday afternoon. The heatmap above reflects long-term patterns; this audience is heavily international, so absolute peak time matters less than consistent posting in any reasonable window.
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.
