Hey Product Hunt! 👋 I built ASOF because I wanted to answer: "What was actually trending when X launched?" We scrape Hacker News, GitHub Trending, Reddit, and Product Hunt every 30 minutes. So far we have 1,400+ snapshots. You can: 📸 Browse any snapshot to see what was hot ⚖️ Compare two dates to see what changed 🔥 Track which topics are rising vs falling Free tier gives you 7 days. Pro unlocks the full archive. Still early - would love feedback on what would make this useful for you.
