UTM links answer a simple question: where did this visit come from? Google Analytics reads campaign parameters such as source, medium, and campaign from the destination URL. The format is simple, but typing the same values by hand gets old fast. One spelling change can also split one campaign into two rows.
IndieUTM builds the URL in your browser. Enter the destination, source, medium, and campaign, then copy the finished link. Optional content and term fields are there when you need more detail.
Presets remember combinations you use often. Recent links let you reuse or copy the last eight. Both live in localStorage on that browser. IndieUTM does not send those values to its server, sync them to an account, or publish them.
The builder follows Google Analytics’ campaign parameter names and uses the browser’s URL parser to encode values without breaking existing query parameters or fragments. It will never add an account, card, premium plan, or public campaign history.
