For vibe coders

Analytics that doesn't ruin the vibes.

No dashboard to babysit. No third-party cookies. No 47 KB tracker. Just a snippet that works, an API that answers, and a free tier that won't bite. Built for solo founders, weekend launchers, and anyone whose roadmap is a Notion page.

Set up in four steps.

Total time: about as long as it takes to make coffee.

Step 1

Sign up

Email + password, or GitHub. You're in the dashboard 10 seconds later, looking at a project, a pk_live_ key, and a script tag.

Step 2

Paste one line

Drop the <script> in your <head>, or `npm i @millimetric/track` if you prefer. Page views, UTMs, fbclid — captured automatically.

Step 3

Fire custom events anywhere

Curl from a Vercel cron. Track from a Bun script. POST from a Worker. Same endpoint, same shape, same key.

Step 4

Privacy that holds up to a lawyer's read

No cookies, no fingerprints, no raw IPs at rest. First-party only — most teams can drop the third-party tracker banner.

app/layout.tsx — Next.js 15
<Script
  src="https://api.millimetric.ai/v1/a.js"
  data-key="pk_live_…"
  strategy="afterInteractive"
/>

// later, on any user action:
import { track } from "@millimetric/track";
track("upgrade_clicked", { plan: "pro", source: "pricing" });

That's the entire integration. The dashboard for stats? Optional. The MCP server for an agent? Already there.
