OpenRev vs DataFast

DataFast describes itself as “Revenue-first analytics”

The short answer

DataFast is a hosted, subscription service for revenue-first analytics. OpenRev does the same core job, linking visitors and marketing channels to the payments they lead to, but it is free, MIT-licensed software that you run on Cloudflare, Docker or Node.js. Pick DataFast if you want nothing to host. Pick OpenRev if you want to own the code and the data and pay nothing for the software.

The main differences

Who runs it

DataFast hosts everything: you sign up and add a script. OpenRev runs on infrastructure you control. Its setup wizard deploys it in one command, and you keep it updated with npm run update.

What it costs

DataFast starts at $9/month for 10k monthly events and is priced by event volume, where pageviews, payments and goals all count. Its FAQ says that past your plan's limit it keeps tracking but locks the dashboard until you upgrade. OpenRev's software is free with no event limits; you pay only your host.

Revenue reports

Both link payments to the visitor and channel that produced them, and both show customer lifetime value. DataFast also reports MRR, subscription upgrades and downgrades, and churn, which OpenRev doesn't yet.

Where the data lives

With DataFast your data sits in DataFast's service. With OpenRev it sits in your own D1, SQLite or PostgreSQL database, which you can query directly.

Alerts and apps

DataFast sends an email when a goal fires and has iOS and Android apps. OpenRev sends payment, goal, traffic-spike and digest alerts to Slack, Discord, Telegram, email or webhooks, and has a web dashboard.

Which one fits you

Choose DataFast if

  • You don't want to run or update any infrastructure.
  • You want MRR, churn and subscription-change reports.
  • You want native iOS and Android apps.

Choose OpenRev if

  • You want the software free, with no event-based limits.
  • You want the data in your own database.
  • You sell through Creem, Gumroad, Paystack or Razorpay, which DataFast's site doesn't list as integrations.
  • You want alerts in Slack, Discord or Telegram.
  • You want code you can read, audit and change.

Switching from DataFast

OpenRev understands DataFast's window.datafast() calls, data-fast-goal attributes, cookies and datafast_visitor_id checkout metadata, so for most sites switching means changing the script tag and reconnecting payment providers. The migration guide has the steps.

OpenRev and DataFast: questions

Is OpenRev a free alternative to DataFast?

Yes. OpenRev is open source under the MIT license and free to use, with no event limits. Like DataFast, it attributes payments from providers such as Stripe, Lemon Squeezy, Paddle and Polar to the visitors and channels that brought them in. The difference is that you host it yourself, on Cloudflare, Docker or Node.js.

Can I self-host DataFast?

DataFast's website doesn't offer a self-hosted version: it is a hosted subscription service. If you need to self-host revenue analytics, OpenRev runs on Cloudflare Workers, Docker or Node.js.

Do I need to change my DataFast tracking code to use OpenRev?

Usually only the script tag. OpenRev's tracker accepts DataFast's window.datafast() calls, data-fast-goal attributes and datafast_visitor_id checkout metadata, and its API has DataFast-compatible endpoints.

Try OpenRev on your own site

One command sets it up on Cloudflare, Docker or Node.js. It's free.
