# DataPenny

> DataPenny is open-source, revenue-first web analytics. It shows which traffic source (a post, a search, a referrer, a campaign, an AI assistant) brought each paying customer, for Stripe, Dodo Payments, Razorpay, Lemon Squeezy, Polar, Paddle and Creem. It runs on your own Cloudflare account as a Worker and a D1 database.

## Key facts

- License: AGPL-3.0. The repository opens at launch.
- Self-hosted: free, unlimited websites and events, on your own Cloudflare account. Cloudflare's free plan fits most small sites, roughly 25,000 pageviews a day. Busier sites pay Cloudflare $5 a month.
- Cloud: not available yet. Planned with a small free tier and paid tiers of $9, $19 and $49 a month by events. The waitlist gets early access and a lifetime deal.
- Payment providers connect natively: Stripe, Dodo Payments, Razorpay, Lemon Squeezy, Polar, Paddle, Creem. Anything else can use the Payments API.
- Past sales import, last 12 months: Stripe, Dodo Payments, Razorpay, Lemon Squeezy, Polar.
- Attribution models per site: last non-direct (default), first touch, last touch.
- Reports: revenue by source, peak hours, scroll depth and reading time, path to purchase, lifetime value by first source, funnels, goals, chart notes, a live 3D globe with OpenFreeMap tiles.
- Alerts: Telegram, up to five chats, for sales, refunds, traffic spikes and a daily digest.
- AI agents: a built-in read-only MCP server at /mcp, a CLI with JSON output, and read-only API keys.
- Privacy: per site, first-party cookies, cookieless (daily-rotating salted hash), or cookieless until consent.
- Tracking script: about 3 KB gzipped. DataFast goal attributes, window.datafast() and visitor metadata work unchanged.

## What DataPenny doesn't do

No teams or roles, no native mobile apps, no Slack alerts, no Search Console keywords, no AI crawler tracking, no session replay or heatmaps of clicks.
