About

twelvebit is built by Rozzabuilds.

An independent analytics product for founders who want to know which channels bring paying customers, set up by the coding agent they already use.

Who makes it

twelvebit is designed, built and run by Rozzabuilds. You can follow the work and ask questions on X: @rozzabuilds. Every change ships in the open on the changelog. The first public release was on 17 October 2026.

Why it exists

Most analytics tools count visitors. A founder needs to know which visitors pay. twelvebit joins each payment to the visit that led to it, so you see revenue by channel, campaign and page next to the traffic. See revenue attribution.

Setup should not take an afternoon. You paste one prompt into Claude Code, Codex or Cursor, and the agent installs the tracker, writes the tracking plan and checks the first events. Later the same agent reads the numbers through the MCP server. See agent setup.

Rules

The rules twelvebit follows.

  • Data stays in the EU

    The app runs in Frankfurt, Germany, and the database in Vienna, Austria. The list of subprocessors is public.

  • No IP addresses stored

    twelvebit uses the IP address only while it handles a request. Cookieless mode stores nothing on the device.

  • Your setup lives in your repo

    The tracking plan is analytics.yaml in your code. Your agent changes it in a pull request that you review.

  • Honest about the limits

    No session replay, heatmaps of clicks, A/B tests or cohort reports. The docs say when another tool is the better choice.
