Why TechLinkss

Frequently asked questions

What kinds of links can TechLinkss expand?

Any HTTP(S) URL that uses a redirect — including Bitly, t.co, TinyURL, ow.ly, buff.ly, youtu.be, lnkd.in, fb.me, l.facebook.com, l.instagram.com, snapchat redirect URLs, Amazon amzn.to, Telegram t.me, WhatsApp wa.me, and many more.

Is it safe to paste any short URL here?

Yes. Our scanner only performs HEAD/GET requests against the link, follows redirects, reads the response headers and the public HTML metadata. We never execute scripts. We block requests that resolve to private network IPs or to non-HTTP protocols.

Do you store the full URL I paste?

We keep a small record of analyzed links (the submitted URL, the final URL, the redirect chain and basic page metadata) so the result has a permanent /u/<id> page and so we can show statistics by provider. We never store passwords, tokens or query parameters that look like authentication data. See our privacy policy.

Why don’t you provide a public API?

To prevent abuse, every analysis is performed via the website. The internal scanner is bound to localhost and is not reachable from the public internet.
