Everything, no upsell

The whole toolkit, free forever.

No "pro" tier hiding the useful features. Everything below ships in the open-source core.

Rust-fast redirects

An Axum + Redis core resolves links in microseconds, built to index billions of rows.

Privacy by default

Click data stays on your instance. We don't sell it or follow visitors across other sites.

Honest analytics

Clicks, geography, devices and referrers — first-party, in real time, no sampling.

Branded QR codes

Every link ships with a QR — add your brand colour and logo, export PNG or SVG.

Password & limits

Gate sensitive links behind a password, cap total clicks, or schedule a window.

Expiring links

Set a start and an end. Campaigns turn themselves off when they should.

Your server, your rules

Up and running in one command.
