About Blue Horizons
Updated 2026-07-25
Blue Horizons answers a question Bluesky itself does not: who is actually on the other side of your follow graph? Not how many followers you have — who followed you and left, who never followed back, who you keep following out of habit.
What it does
- Free public analysis. Type any handle and see followers, following, mutuals and the accounts that don’t follow back. No sign-in, nothing installed, nothing stored about you.
- Bulk clean-up, once you connect. Filter your graph, select what you want, and follow back or unfollow in one go — with a protected list that bulk actions never touch.
- Rate safety built in. Bluesky charges every follow and unfollow against an hourly and daily allowance. Blue Horizons tracks that allowance itself and stops before the network does.
What it will never do
- Post, reply, repost, or send messages. It reads your graph and writes the follows you asked for. That is the whole surface.
- Act on its own. There is no background bot, no auto-follow, no scheduled churn. Every write is one you selected and confirmed.
- Sell your data. We show ads, which is how the tool stays free. We do not sell, rent or share the graph data connected accounts give us access to.
Why it is free
Because the alternative — a paywall on a utility most people need twice a month — would mean almost nobody uses it. The public pages carry ads; that pays for the server, and the app itself stays deliberately light on them: never inside a list you are clicking through, never next to a destructive button.
Who builds it
Blue Horizons is an independent project. It is not affiliated with, endorsed by or operated by Bluesky Social PBC. “Bluesky” and the AT Protocol are theirs; we just build on the public API like any other client.
Found a bug, or a feature that is obviously missing? There is a feedback box inside the app, and it goes straight to the people writing the code.
