fckurl

Shorten links in one click.

Sequential IDs, base62 encoded — link #1 is one character. Free, anonymous, optional account for tracking and custom domains.

Compact codes

Every link gets the next available base62 code. No padding, no collisions, no wasted characters.

Anonymous by default

You don't need to sign up. Sign in only if you want to track clicks, edit links, or use a custom domain.

Bring your own domain

Verify your domain via DNS, then point links at go.yourdomain.com. Same dashboard, same API.

Open API

Anyone can call POST /api/v1/links. Custom-domain calls just add an X-Api-Key header.

How it works

  1. Paste a URL above and we issue a base62 code from a strictly-increasing sequence.
  2. The first link is 1, the 62nd is Z, the 3,844th is ZZ — compact codes with no padding or wasted characters.
  3. Sign in to keep your links, see click counts, attach a custom domain, or generate API keys.
