What apps are built with Firebase?

Our index tracks 13 revenue-backed businesses that run on Firebase. Examples include Joinable, an Android-first calorie counter at about $80K MRR that runs almost entirely on Google; Waitly, a solo restaurant waitlist SaaS at $40K a month; and Harpagia, a text-based RPG at about $13K a month built by a former Meta engineering manager.

How much does Firebase cost?

Firebase has a no-cost Spark plan that needs no payment method and a pay-as-you-go Blaze plan for more services and usage. Real bills in our index range from about $25 a month for a yoga app to about $700 a month for Waitly, a SaaS doing over $40K a month, so cost scales with usage rather than plan.

Is Firebase good for a startup?

For mobile apps, the businesses in our index say yes: 7 of the 13 report $10K a month or more on it. Founders cite built-in sign-in for Google, email and Apple, and no servers to run. It suits teams already living in Google's tools; web apps built with AI coding tools lean to Supabase instead.

Firebase or Supabase: which do profitable apps use?

Both, but rarely together: 0 businesses in our index name both at the latest count. Supabase appears in 36 businesses and Firebase in 13. Firebase skews to mobile apps and Google-centric stacks; Supabase skews to web SaaS built with Claude Code, Cursor or Lovable. Our Supabase vs Firebase comparison goes deeper.

Can you build a Firebase app without coding?

Partly. App Alchemy's founder built an MVP with Next.js, React and Firebase in two weeks using Cursor, and Stoppr's founder, a former quant trader with no developer background, recommends Firebase precisely because sign-in comes ready-made. You still have to understand your data rules and costs.

What Founders Build on Firebase: 13 Revenue-Backed Apps, Costs and Stacks

13 businesses built on Firebase, from an $80K MRR Android app to a solo restaurant SaaS paying $700 a month for it: what Firebase costs and when it fits.

ProvenStartups·Published 2026-10-17·Updated 2026-10-21·Live list

Firebase is the backend of choice for mobile-first founders and teams that live in Google's tools. The ProvenStartups index holds 13 revenue-backed businesses that run on Firebase; 77% are run by one person, and 7 report $10K a month or more. Its users look different from the Supabase crowd: more mobile apps, more former big-tech engineers, and more founders who also buy from Google for analytics and ads.

How we count: a business is listed only if its own interview names Firebase in its stack. On October 17, 2026 we removed entries that named Firebase only as one of two options or in a list of suggested analytics tools.
