Show HN: Free UTM Builder – Instantly generate campaign tracking URLs

I built a free UTM Builder tool to quickly generate UTM-tagged URLs for campaign tracking (Google Analytics, ads, emails, etc.). No sign-up, no clutter—just input your parameters (source, medium, campaign, etc.) and get a clean URL instantly.

Why I made this: I found most UTM builders either overcomplicated or packed with ads. This one is dead simple, works offline after first load, and respects your privacy (no tracking).

Would love feedback or feature suggestions.
