Bio Link Checker
Check that the links in your bio, captions and link-in-bio page actually work: status code, redirect chain, HTTPS and response time — before your audience finds out they don't.
Runs in your browser. Nothing you enter is sent to our servers.
Bio links break quietly: a shop moves, a landing page expires, a shortener stops paying its bill, a redirect chain gets so long that in-app browsers give up. This checker follows each link the way a phone would and shows the final status, every redirect hop, whether the page is served over HTTPS and how fast it answers — so you can fix the link before it costs you clicks.
How this checker works
Our server sends a request to each URL (a lightweight HEAD request, falling back to GET), follows up to five redirects and records the status code, the final address, the protocol and the response time of each hop. Private and internal addresses are refused, and each network is limited to 30 checks every 10 minutes to keep the service fast for everyone.
Frequently asked questions
What do the status codes mean?
200 = fine; 301/302 = redirect (fine if it ends in 200, but keep chains short); 404 = page missing; 410 = removed; 403 = blocked; 5xx = the site is having problems; 0 = no answer at all (typo in the domain, DNS or a server that is down).
Why does my link redirect three times?
Typically http → https → www → final page, or a shortener in between. Each hop costs time on mobile networks; link straight to the final https address where you can.
Can you check links behind a login?
No — the checker sees what an anonymous visitor sees. A 403 or a redirect to a login page means the link needs an account.
Does Instagram block certain links?
Instagram blocks links it considers spam or unsafe and shows a warning page. If a link works here but not in the app, shorten it with a reputable service or link to a page on your own domain instead.
