FAQ

Everything you need to know about using unshorten.app

Why can't this run fully in the browser?
Most websites block cross-origin requests (CORS) and automated checks. We run the redirect tracing server-side to reliably follow Location headers and return the final destination.
Do you store the links I check?
By default, no. We only process the link to follow redirects and return metadata. We may keep short-lived logs for abuse prevention and rate limiting.
What exactly do you fetch?
We don't proxy page content. We only follow redirects and read response metadata (status codes and Location headers). For some sites, we may send a minimal request to detect redirects when HEAD is blocked.
Why did a link fail to resolve?
Some websites block automated requests, require JavaScript, or use anti-bot protection. In those cases, we may not be able to follow the redirect chain all the way to the final page.
What are "suspicious flags"?
They are lightweight heuristics that highlight common phishing tricks (punycode domains, mixed scripts, IP hosts, unusual ports, very long queries, etc.). They are not a guarantee of maliciousness — use them as a warning signal.
Can you remove tracking parameters safely?
Yes — the "Clean tracking parameters" option removes common trackers like utm_*, fbclid, gclid, and others. If you rely on specific affiliate or partner parameters, double-check before sharing.
Which short links do you support?
Most common shorteners work (bit.ly, t.co, tinyurl, and many others). If a shortener requires JavaScript or blocks automated requests, results may be limited.
Is there an API?
Not yet publicly. Pro (Early Access) will include API access and higher limits for automations and integrations.
