What FSB does

Everything is free. Signing in adds a dashboard, favourites and alerts.

Four live tests

Search ban, suggestion ban, ghost ban and reply deboosting, each tested on its own from a logged-out view.

Confirmed results

Detected, clear or unknown. New restrictions are re-tested before they show; failed requests never overwrite a confirmed result.

Sensitive flag

Reported separately, so an old setting is not mistaken for a search ban.

History

Every check is kept: see when a restriction started and when it lifted.

Posts & analytics

Latest posts with media, plus averages for likes, reposts, replies, views and engagement.

Global Board

Accounts checked recently, their status, and who is watching them live.

Favourites

Pin accounts and get an email when one of them posts.

Dashboard

Your own accounts, re-checked automatically.

Share card

A status image for every account, used in link previews on X and Discord.

Badge

A live SVG status badge for a site, link-in-bio or README.

JSON API

Profile data and test results for any public account. No key.

Index

Restriction rates across every checked account, live.

Live check

Check an account

Four live tests from a logged-out view. No password, no app permissions.
