OpenRev vs Umami

Umami describes itself as “Open-source web and product analytics”

The short answer

Umami is open-source (MIT), cookieless web and product analytics that you can self-host for free or use on Umami Cloud. Like OpenRev, it is MIT-licensed and has funnels, journeys and an MCP server. The main difference is revenue: Umami reports revenue from events your site sends with an amount, while OpenRev connects your payment provider and attributes every payment, renewals included, to the visitor's source.

The main differences

Revenue

Umami's revenue report adds up events that your site sends with revenue and currency properties. It doesn't connect to payment providers. OpenRev receives payments, renewals and refunds from 11 providers by signed webhook, so no purchase code is needed on your site.

Where it runs

A self-hosted Umami needs Node.js and a PostgreSQL database. OpenRev runs on Cloudflare Workers with D1, which fits Cloudflare's free plan for small sites, or in Docker or on Node.js with SQLite or PostgreSQL.

Product analytics

Umami also offers retention reports, session replays and heatmaps (on Cloud, replays and heatmaps need the $200/month Business plan). OpenRev doesn't have session replays or heatmaps.

Cookies

Umami is cookieless by default. OpenRev stores a first-party visitor ID by default, for attribution across days, and offers a cookieless mode per site.

Alerts

Umami sends scheduled email reports on Cloud Pro and above. OpenRev sends payment, goal, traffic-spike and digest alerts to Slack, Discord, Telegram, email or webhooks.

Which one fits you

Choose Umami if

You want session replays, heatmaps or retention reports in the same tool.
You want cookieless tracking by default.
You want the option of a managed cloud with a free tier.

Choose OpenRev if

You want revenue from Stripe, Lemon Squeezy, Paddle or eight other providers without adding purchase events to your site.
You want to run on Cloudflare's free plan, without a PostgreSQL server.
You want sale and traffic alerts in Slack, Discord or Telegram.

Switching from Umami

Run both side by side while you compare. Umami's custom events become OpenRev goals, and revenue no longer needs a client-side event once your payment provider is connected. Umami history isn't imported.

OpenRev and Umami: questions

Is Umami open source like OpenRev?

Yes. Both are MIT-licensed and free to self-host. Umami self-hosts on Node.js with PostgreSQL; OpenRev runs on Cloudflare Workers with D1, in Docker, or on Node.js with SQLite or PostgreSQL.

Does Umami track revenue?

Yes, from events your site sends with revenue and currency properties, and it has an attribution report for them. It doesn't connect to payment providers. OpenRev gets payments straight from the provider through signed webhooks, so renewals and refunds count without extra code.

Yes, an official read-only one, on Umami Cloud's Pro plan and above or self-hosted from version 3.4. OpenRev's MCP server is built into every install.
