How it works

From first click to paid, on one timeline

Pageview analytics tell you where traffic comes from. OpenRev tells you which of it pays — by joining your tracking data with your payment provider's webhooks.

  1. 1

    A visitor arrives

    The script records the session's source, campaign, landing page, country and device — and gives the visitor an ID.

    They browse and convert

    Pageviews, goals and engagement time build a journey across every visit, so you see the path, not just the last click.

    Revenue is attributed

    The payment is matched to the visitor and credited to the session that brought them in.

Change the model, keep the history

OpenRev stores every touchpoint, so the attribution model is a view, not a setting baked into your data. Switch and every past payment is re-attributed instantly.

Last non-direct

Default. Credits the last campaign or referral, ignoring direct returns.

Last touch

Credits the session the purchase happened in.

First touch

Credits whatever introduced the customer.

How payments find their visitor

  • Visitor ID passed in checkout metadata (added to Stripe, Lemon Squeezy and Gumroad links for you)
  • The checkout success page the visitor lands on
  • The customer's email, if you identify signed-in users
  • Earlier payments from the same customer — renewals and refunds follow the original

  • An AI channel

    Visits from ChatGPT, Perplexity, Claude, Gemini, Copilot and more get their own channel — from the referrer or utm_source.

  • Alerts where you work

    Sales, refunds, goals, traffic spikes and daily or weekly digests to Slack, Discord, Telegram, email or any webhook.

  • Teams and share links

    Invite teammates with roles. Share a public dashboard link that never exposes personal data.

  • REST API and MCP server

    Website keys, account tokens and an OpenAPI spec. AI assistants can query your numbers through the built-in MCP server.

  • DataFast-compatible

    window.datafast(), data-fast-goal and datafast_visitor_id keep working, and the API has compatible endpoints.

  • A 3.9 kB script

    SPA and hash routing, engagement time, outbound clicks and scroll goals in a script smaller than most favicons.

  • Cookieless mode

    Switch a site to a daily-rotating hash so nothing is stored on the visitor's device.

  • Ad-blocker resilient

    Proxy recipes for Next.js, Vercel, Netlify, Cloudflare, Nginx and more — with the visitor's real location kept.

  • Cross-domain tracking

    Follow visitors across your marketing site, app and checkout domains, and across subdomains.

  • Multi-currency revenue

    Payments in any currency are converted to your site's currency. New, renewal and refund revenue are kept apart.

  • Filter everything

    Filter by any dimension, compare periods, pin date ranges and annotate the chart with notes.

  • Exclusions and export

    Bot filtering, IP, country and hostname exclusions, and CSV export of your data.

Get started

From zero to revenue analytics in one command

A setup wizard deploys OpenRev to your own infrastructure. No account to create, no vendor in the middle.

$curl -fsSL https://raw.githubusercontent.com/CrowdLinker/OpenRev/main/install.sh | bash

Clones the repo, installs dependencies and runs the setup wizard. Uses Docker instead if Node.js 22.13+ isn't installed.

  1. 1

    Pick a target

    Cloudflare, Docker or Node.js. The wizard asks a few questions and writes the config.

  2. 2

    Deploy

    It provisions the database, sets a secret and deploys. Migrations run on start.

  3. 3

    Add the script

    Create a site in the dashboard and paste one <script> tag into your website.

  4. 4

    Connect payments

    Paste the webhook URL into Stripe, Lemon Squeezy, Paddle or any other provider.

Deploy anywhere

Runs where you already run things

The same server code runs on Cloudflare Workers and on Node.js. The same SQL schema runs on Cloudflare D1, SQLite and PostgreSQL. Pick what fits; move later if you outgrow it.

FAQ

Questions, answered

Something else? The documentation covers setup, tracking, revenue and the API in depth.

What is OpenRev?

OpenRev is free, open-source (MIT) web analytics that shows which traffic sources, campaigns, pages and countries bring in revenue, not just visits. It connects payment providers such as Stripe, Lemon Squeezy, Paddle and Shopify to visitor sessions, and you host it yourself on Cloudflare Workers, Docker or Node.js, so the data stays in your own database.

Is OpenRev really free?

Yes. OpenRev is open source under the MIT license. There is no paid tier, seat limit or usage cap. You only pay for the infrastructure you run it on, and small sites fit within Cloudflare's free plan.

How does revenue attribution work?

The tracking script gives each visitor an ID and records their sessions with source, campaign, country and device. When your payment provider sends a webhook, OpenRev matches the payment to the visitor (from checkout metadata, the success page, the customer's email or earlier payments) and credits the session that brought them in. You can switch between last non-direct, last touch and first touch at any time, and past payments are re-attributed instantly.

Which payment providers are supported?

Stripe, Lemon Squeezy, Paddle, Polar, Dodo Payments, Creem, Shopify, WooCommerce, Gumroad, Paystack and Razorpay are built in. Anything else can post payments through the configurable custom webhook or the Payments API. Every webhook is signature-verified and processed idempotently.

Does it use cookies? What about privacy laws?

By default the script stores a first-party visitor ID. Turn on cookieless mode per site and visitors are counted with a daily-rotating hash instead, so nothing is stored on the device. Because you self-host, the data never leaves infrastructure you control. Whether you need a consent banner depends on your jurisdiction and setup — the privacy guide walks through the options.

Will ad blockers block it?

Some blockers block known analytics domains. The docs include proxy recipes for Next.js, Vercel, Netlify, Cloudflare Workers, Nginx, Caddy, Express, Laravel, Django, Astro and more, so the script and events are served from your own domain. OpenRev keeps the visitor's real IP and location when requests are proxied.

I use DataFast today. How hard is it to switch?

The tracker understands DataFast's window.datafast() calls, data-fast-goal attributes and datafast_visitor_id metadata, and the REST API includes DataFast-compatible endpoints, so most sites only swap the script tag. There is a step-by-step migration guide.

Which databases can I use?

Cloudflare D1, SQLite (via Node's built-in driver, no native modules) or PostgreSQL. The same schema runs on all three and migrations are applied automatically on startup.

Can AI agents use my analytics?

Yes. OpenRev ships a REST API with an OpenAPI spec and a built-in MCP server at /mcp, so assistants that speak MCP can query traffic, revenue, funnels and visitors with an API token you create.

How do I update?

Run npm run update in your OpenRev folder. It pulls the latest code, reinstalls and redeploys to the target you picked during setup (on plain Node.js you restart the process afterwards). Database migrations run automatically on start.
