Supabase’s Pro plan is a single $25/month entry that bundles database, auth, storage and edge functions. Firebase, by contrast, offers a collection of services that bill separately, with the Blaze calculator kicking off at $300/month for a fully loaded stack.

The table shows that Supabase keeps the bill simple: a flat fee plus a few predictable overage rates. Firebase’s model splits costs across individual services, so the final invoice depends on which features you actually use.
When you need a Postgres database, Supabase’s $25/month gives you a ready‑made backend. If you require real‑time data sync for a mobile app, Firebase’s $5/month Realtime Database may be attractive, but you’ll also pay for hosting, SQL Connect, and any additional services you add. The Blaze calculator’s $300/month figure is a worst‑case scenario for a production app that uses many of Firebase’s services.
Supabase’s Team tier jumps to $599/month, adding SSO, backup control and industry certifications, targeting enterprises that need compliance. Firebase scales linearly with usage; there is no sudden jump to a higher tier, but the invoice can grow as you add more services.
In short, if you want a predictable, all‑in‑one backend at a low entry cost, Supabase is the clear pick. If your architecture relies heavily on [Google](/entry/playwright-vs-cypress-vs-puppeteer-end-to-end-testing-and-where-cypress-charges)’s ecosystem and you anticipate using multiple Firebase services, the granular, pay‑per‑feature model may suit you better, even if the baseline price is higher.
