Bluesky Profile Checker
Any handle → followers, following, posts, DID and account age. No login. The lookup goes straight from your browser to Bluesky's public API — nothing touches a server of mine.
How it works
This page is static HTML with ~30 lines of inline JavaScript and no analytics. When you hit Check, your browser calls public.api.bsky.app/xrpc/app.bsky.actor.getProfile — Bluesky's unauthenticated AppView endpoint — and renders the JSON. View-source shows everything. The same API also exposes followers, follows and post history without auth (app.bsky.graph.getFollowers etc.), which is unusual among social networks and what makes tools like this possible.
One deliberate choice: if an account carries the !no-unauthenticated self-label (the "don't show my account to logged-out users" setting), this tool shows a notice instead of the profile. The public API serves the data regardless — respecting the label is up to each app, and this one does.
