twelvebit is privacy-friendly web analytics with revenue attribution. A 5 KB script counts visits and goals. Payments from Stripe, Polar, Lemon Squeezy, Paddle or Dodo Payments are credited to the visit before the payment, so you see revenue by channel, campaign and page. Your coding agent sets it up with one prompt, and data is processed in the EU.

Agent setup

One prompt. Your agent does the setup.

Paste the prompt into Claude Code, Codex or Cursor. The agent adds the tracker, writes your tracking plan, connects payments and checks that the first events arrive. You review the diff.

Funnels

Find the step where people leave.

Ask and MCP

Ask in plain words. Get a sentence and a chart back.

Every answer names its date range and attribution model, and shows the query behind it. The same tools work in your coding agent through the MCP server.

Question: Which blog posts brought paying customers last month?

/blog/where-to-launch brought the most: 58 customers and $2,940. That is 25% of all revenue. The next post brought less than half of that.

Goals and tracking plan

Your tracking plan lives in your repo.

analytics.yaml lists every event and its props. It goes through code review like the rest of your app, and the dashboard shows the health of each event.

Privacy

Useful numbers, without third-party cookies.

twelvebit counts visits and payments, not people across the web. You decide if the tracker uses cookies at all.

No third-party cookies
The tracker sets two first-party cookies on your own domain: _tb_vid for one year and _tb_sid for 30 minutes. Nothing is shared with ad networks.
Cookieless mode
Turn it on and the tracker sets no cookies at all. The visitor ID becomes a hash that changes every day. You keep page views, sources, goals and revenue.
IP addresses are not stored
twelvebit uses the IP address only while it handles a request, for example to apply your exclusion rules. It never writes the address to the database.
Data stays in the EU
The database runs in Germany. Your analytics data is processed in the EU.

Bots and AI crawlers

Bots stay out of your visitor numbers. twelvebit sorts AI crawlers by what they do: answer a question now, index the page for search, or collect it for training.

Ask for a custom plan

Starter and Growth start with a 14-day free trial: add a card at checkout, pay nothing today, and cancel any time before day 14. The launch price is a lifetime discount for as long as you stay subscribed to the same plan; a cancel or a plan change ends it. Every plan includes the REST API, the CLI and the MCP server. An event is a page view or a custom goal. Over the limit, tracking goes on and the dashboard asks you to pick a larger plan. Prices in US dollars; Dodo Payments, our merchant of record, adds sales tax or VAT where it applies.

Questions

Questions people ask before they start.

What does the setup prompt do?

You paste one prompt into Claude Code, Codex or Cursor. The agent adds the tracking script, tracks the 3 to 8 actions that matter most, writes the tracking plan to analytics.yaml, passes the visitor ID to your checkout and checks that events arrive. You review the diff like any other change. See every step.

Do I need a coding agent?

No. You can paste the script tag into your site yourself, or run the CLI. The agent only saves you the work of finding the right files and naming the events.

Which payment providers work for revenue attribution?

Stripe, Polar, Lemon Squeezy, Paddle and Dodo Payments. The visitor ID goes into the checkout metadata, so each payment joins the visit that started it.

Does twelvebit use cookies?

The tracker sets two first-party cookies on your domain: _tb_vid (one year) and _tb_sid (30 minutes). There are no third-party cookies. If you turn on cookieless mode, the tracker sets no cookies at all.

Where is my data stored?

In the EU. The database runs in Germany. twelvebit does not store IP addresses.

Is there a free trial?

Yes. Starter and Growth start with a 14-day free trial. You add a card at checkout and pay nothing until day 14; cancel before then and you pay nothing.

What is the launch price?

A lifetime discount for the first 50 paid places on Starter or Growth at 10k or 100k events a month. Places 1 to 10 get 50% off, and after each 10 places the discount goes down by 10 points. 50 places are left; the next one gets 50% off. The discount lasts for as long as you stay subscribed to the same plan. If you cancel, or change the plan, the number of events or monthly and yearly, it ends and does not come back. If you go over your events, tracking goes on, and a larger plan has the standard price.

What counts as an event?

A page view or a custom goal, such as signup or purchase. Plans differ by the number of events a month, sites and people.

Can my agent read the numbers later?

Yes. twelvebit has an MCP server and a REST API. Your agent can ask for revenue by channel, a funnel or one visitor's journey, and get structured data back.

Will the script slow down my site?

The script is about 5 KB gzipped and loads with defer, so it does not block the page from rendering.
