What is ThunderSky?

ThunderSky is an alternative front page for Bluesky, inspired by Hacker News. It surfaces the most engaged-with content from across the network, helping you discover interesting posts you might have missed.

How does it work?

ThunderSky connects to Bluesky's Jetstream Firehose, processing thousands of posts and interactions in real-time. Posts are ranked using an algorithm that considers:

  • Like count
  • Reply count
  • Repost count
  • Post age (newer posts rank higher)
  • Account size (smaller accounts get a slight boost)

Points

Points = likes + replies + reposts. Points are weighed against the age of the post and size of account to determine a post's rank.

Updates

The front page updates every few seconds, showing the top 25 posts based on the current rankings.
