Configuration

Three screens control where Trell tracks, how campaigns are tagged and how much room your workspace has.

Domains

Tracking only runs on the hostnames in your allowlist — add trell.relake.co style hostnames, no protocol or path. Anything else is ignored, which keeps staging, localhost and copycats out of your analytics.

UTM templates

Save the six UTM parameters as named, reusable templates instead of retyping query strings for every campaign. Copy the built string straight to clipboard when you need it.

Plans & limits

Free covers 5,000 events and 3 domains — enough to instrument a side project end to end.

Pro raises the limits to 50,000 events and 100 domains and unlocks webhooks. Usage meters in billing show exactly where you stand, and upgrades run through checkout in a couple of clicks.
