# The 7 Best Firebase Alternatives in 2026

- Tool: Tool Comparisons
- Last updated: August 2026

## TL;DR

Supabase is the best Firebase alternative for most people — open-source Postgres with auth, storage and functions, and no uncapped billing surprise. Appwrite is the pick if you want to fully self-host, Neon if you only need serverless Postgres, and AWS Amplify if you're already on AWS. Nhost, PocketBase and Convex cover open-source and lightweight needs. Pricing is as of 2026.

## Frequently asked questions

### What is the best alternative to Firebase?

Supabase is the most popular choice — it gives you open-source Postgres (real SQL) with auth, storage, functions and realtime, and avoids Firebase's uncapped billing model. Appwrite is the best fully self-hostable option, and Neon is ideal if you only need a serverless Postgres database.

### Is Supabase or Firebase cheaper?

Supabase uses a predictable flat tier (free, then $25/mo Pro), which many find easier to budget than Firebase's Blaze plan, which is pay-as-you-go with no default spending cap. Firebase's free Spark tier is generous for small apps, but costs can climb quickly and quietly at scale without budget alerts set.

### Why do people move off Firebase?

Common reasons are wanting relational SQL instead of NoSQL, concern about the Blaze plan having no default spending cap, hitting NoSQL query limitations, and wanting an open-source backend they can self-host. Cold starts and permission-denied security-rules errors also frustrate some teams.

### Which Firebase alternative supports real-time data?

Supabase offers Realtime over Postgres, Convex is built around reactive queries that update the UI live, and PocketBase and Appwrite include realtime too. If real-time sync was your main reason for choosing Firebase, Convex and Supabase are the closest in spirit.

### Can I self-host a Firebase alternative?

Yes. Supabase, Appwrite, Nhost and PocketBase are all open-source and self-hostable, so you can run your backend on your own infrastructure instead of Google's cloud. Appwrite and PocketBase are especially popular for self-hosting because they bundle everything into a single deployable unit.

### Is it hard to migrate from Firebase?

Moving from Firestore's NoSQL model to a SQL backend like Supabase means redesigning your data schema, so it's more than a copy-paste. Auth and storage usually map over more cleanly. If you'd rather not handle the migration yourself, RapidDev can move and secure your backend for you.
