UTM builder, link checks and A/B test math

UTM Desk Pro and API (coming soon)

UTM Desk’s tools are free and run in your browser. We are planning a paid Pro plan and an API for teams who tag and report on campaign links every week — marketing, growth and analytics people, and the agencies that work for them. Neither is available yet. If they sound useful, leave your email below and we will tell you when they open.

What stays free

  • Every tool on this site, with all of its settings: the UTM and campaign URL builders, the link checker and UTM audit, the email link tagger, the ad-platform parameter builders and the A/B test and conversion-rate calculators.
  • Local processing. Links, lists and numbers you enter stay in your browser and are never uploaded.
  • No sign-up and no limit on how often you use a tool.

What Pro and the API would add

  • Shared naming rules: one list of allowed sources, mediums and campaign patterns for your whole team, applied in the builder so everyone tags links the same way.
  • Saved link lists: keep the links you built, by campaign, and export them when the campaign is reported.
  • Bulk checks: check thousands of tagged links at once against your naming rules and get one report.
  • An HTTP API: build and check UTM links from your own scripts, spreadsheets or publishing tools.

We have not set prices. Joining the waitlist does not commit you to anything.
