UTM Campaign Builder: Build correctly tagged campaign links for GA4

Hi Product Hunt 👋

We’re Bracketworks, a design and dev agency in Dubai. When we audit clients’ GA4 accounts, we often see one campaign split into many rows: “LinkedIn” and “linkedin” counted as two sources, or traffic in “Unassigned” because someone used a medium like “email-blast” that GA4 does not know.

So we built UTM Campaign Builder. Fill in the fields, and it gives you a clean tagged link and a QR code. It makes all values lowercase by default. It warns you about mixed casing, about a medium that GA4 will put in Unassigned, and about parameters that are already on the link. The source and medium fields give suggestions that match GA4’s channel groups, but you can still type your own.

Everything runs in your browser. We do not send or store the links you build.

One known limit: it has no link shortener.

Feedback that would help us most:

Are the warnings clear? Did one stop you from making a mistake?
Do you want saved templates or a shared naming list for your team?
Should we add a link shortener, or do you use your own?

We read every comment.
