Where it sits in the data

fabu.dev's $3.1K MRR is higher than 86% of the 5,602 projects with payment-verified revenue in our dataset; the median across them is $150. Within the “Analytics” category (646 projects) it is higher than 87% (category median $135). Snapshot: 2026-09-02 to 2026-09-30. The dataset only covers founders who chose to publish their numbers, so it leans toward businesses that work; use it for scale, not as an average.

Currency

All figures are in US dollars as published. A rough yuan or euro conversion is not applied here because prices, taxes and acquisition costs differ by country.

Could you build something like this?

My view is that this needs real work. The buyer would be SaaS founders and developers managing multiple products, and distribution would have to come through the Chrome extension and the workflow surface around it. The hard parts are browser-based execution, integrations, account permissions, policy-aware workflows, and support when users manage multiple products.

Verdict: Needs real work.

One thing to take from it

Fabu.dev pairs SaaS product analytics with browser workflows, a free tier, and a $9/mo pro tier for founders managing more products.
