A local-first campaign URL checker

Stop messy UTMs before they reach your reports.

Build a clean campaign URL from the page you are already on, enforce your naming rules, and copy it in seconds—no account and no browsing history sent to our servers.

One narrow job, done well

Faster links. Fewer reporting fragments.

CampaignLint preserves the URL you started with, replaces stale UTM values, applies your convention, and shows problems before copy.

Current-tab speed

Open the extension on a landing page and start with its HTTP or HTTPS URL automatically.

Naming guardrails

Normalize case and separators, restrict source and medium values, and block or warn on mistakes.

Local-first privacy

Generated links, presets, policies, and history stay in Chrome storage on your device.

Simple lifetime pricing

Useful for free. Governance when you need it.
