8 Best Firebase Alternatives (2026)
The closest alternatives to Firebase are Appwrite, Convex, ElectricSQL and InstantDB, with 4 more below. Each shares a comparison category with it, so every rationale here names both tools' real values. Firebase is 11th of 11 on Exit cost (5) — usually where a switch starts.
Why do people look for Firebase alternatives?
Most people searching for Firebase alternatives are not shopping — they already run it and something has stopped fitting. That something is usually a specific number rather than a feeling, so this page starts from the fields where Firebase genuinely trails the rosters it appears in, and only then covers the reasons that never show up in a table.
The measured reasons.
- Exit cost — 5, the weakest of the 11 here. Neon + Drizzle records 1.
- TS inference — No. Convex records Yes.
- Self-hostable — No. Convex records Yes.
- Full-text search — No. Convex records Yes.
- Agent fit — 2, 10th of 11. Convex records 5.
Any one of those is enough on its own if you sized your architecture around it. None of them is enough if you didn't — which is why the list is short and specific rather than a general case against Firebase.
The reasons that never make it into a table. A price rise after a funding round. A licence change that turns a self-host into a subscription. A region you now need and they do not have. An acquisition. A support experience that quietly degrades. None of those are fields, and all of them move teams — which is why every entry below links back to Convex alternatives, where the full field set and its sources live. The ones we catch get logged on the Firebase timeline.
How the shortlist is ordered. Every tool below shares at least one comparison category with Firebase, sorted by how many categories the two overlap in. There is no editorial ranking, no sponsorship and no affiliate link — the order is the overlap count, and the rationale under each is generated from the two tools' own cells, so it names real values rather than adjectives.
1.
Appwrite
Appwrite — Open-source backend platform: databases, auth, storage, functions, self-hostable. It meets Firebase in Convex alternatives. It is ahead on Self-hostable (Yes against No), Exit cost (3 against 5) and TS inference (Partial against No). What you give up: Optimistic writes (No, where Firebase records Yes) and Vector search (No, where Firebase records Yes). Best for teams that must run the whole backend on their own infrastructure. The most complete self-hostable batteries-included option, with the widest OAuth and SDK coverage here. Held back by a console-first model that keeps your schema out of your repo, and by the weakest transaction story on the page.

2.
Convex
Convex — Reactive TypeScript backend: database, functions and live queries in one project. It meets Firebase in Convex alternatives. It is ahead on TS inference (Yes against No), Self-hostable (Yes against No) and Full-text search (Yes against No). What you give up: Entry price ($25 /mo, where Firebase records $0 /mo) and Function timeout (10 min, where Firebase records 60 min). Best for small teams shipping realtime-shaped product fast. The fastest path from empty repo to working realtime feature, and the clearest thinking about transactions on this page. It is also a 4 on exit cost with no SQL escape hatch — a bet worth making deliberately rather than by default.

3.
ElectricSQL
ElectricSQL — Postgres read-path sync: stream subsets of your own database to clients over HTTP. It meets Firebase in Convex alternatives. It is ahead on Self-hostable (Yes against No), Exit cost (2 against 5) and Raw SQL (Yes against No). What you give up: Cron & scheduling (No, where Firebase records Yes) and Auth (bring-your-own, where Firebase records built-in). Best for existing Postgres apps that need live read data without a rewrite. The narrowest tool here and the best-behaved: read-path sync over a Postgres you already own, with an exit close to free. It solves a quarter of what Convex solves, and it is honest about which quarter.

InstantDB
InstantDB — Client-side reactive database with a relational graph model and instant sync. It meets Firebase in Convex alternatives. It is ahead on TS inference (Yes against No), Self-hostable (Partial against No) and Agent fit (4 against 2). What you give up: Entry price ($30 /mo, where Firebase records $0 /mo) and Cron & scheduling (No, where Firebase records Yes). Best for multiplayer or collaborative UIs where every interaction must feel local. The most pleasant developer experience here for collaborative, instant-feeling UIs, and the smallest API surface. The absence of any server-side function runtime is the constraint people hit, usually around the third feature.

5.
Neon + Drizzle
Neon + Drizzle — The DIY baseline: serverless Postgres, a typed SQL query builder, nothing else. It meets Firebase in Convex alternatives. It is ahead on Exit cost (1 against 5), TS inference (Yes against No) and Raw SQL (Yes against No). What you give up: Reactivity (manual, where Firebase records push) and Optimistic writes (No, where Firebase records Yes). Best for teams that already know what backend they want to build. Not a competitor — the yardstick. You write the realtime layer, the auth, the file handling and the scheduler yourself, and in exchange nothing you build is owned by anyone else. Every exit-cost score here is measured against this row. Note that we carry Neon + Drizzle as the do-it-yourself baseline in that roster — the "what if we just ran this ourselves" reference point. The honest answer is usually that it is cheaper and considerably more work.

6.
Nhost
Nhost — Postgres plus Hasura GraphQL, auth, storage and serverless functions. It meets Firebase in Convex alternatives. It is ahead on Self-hostable (Yes against No), Exit cost (2 against 5) and Raw SQL (Yes against No). What you give up: Optimistic writes (No, where Firebase records Yes) and Entry price ($25 /mo, where Firebase records $0 /mo). Best for teams already committed to GraphQL and Hasura. An underrated exit: Postgres plus open-source Hasura means both halves of the stack survive leaving. It is also the quietest project here, which you should weigh against how much you like GraphQL.

PocketBase
PocketBase — One Go binary: SQLite database, auth, file storage, realtime and an admin UI. It meets Firebase in Convex alternatives. It is ahead on Self-hostable (Yes against No), Raw SQL (Yes against No) and Exit cost (3 against 5). What you give up: Optimistic writes (No, where Firebase records Yes) and MCP server (No, where Firebase records Yes). Best for internal tools and side projects where one VPS is plenty. Absurdly good value for single-machine workloads, and the easiest data extraction here — the store is a file you own. The ceiling is real: one writer, one box, and a bus factor of roughly one.

8.
Zero
Zero — Sync engine that puts a queryable client cache in front of your own Postgres. It meets Firebase in Convex alternatives. It is ahead on TS inference (Yes against No), Self-hostable (Yes against No) and Raw SQL (Yes against No). What you give up: Cron & scheduling (No, where Firebase records Yes) and Auth (bring-your-own, where Firebase records built-in). Best for teams with an existing Postgres who want a UI that feels local. The most interesting shape on this page: instant local reads without surrendering the database. You still operate zero-cache and Postgres yourself, and you get no auth, storage or cron — this is a layer, not a platform.

How this list was built
There is no editorial ranking on this page and no sponsorship behind it. The order is mechanical: every tool that shares a comparison category with Firebase, sorted by how many categories the two overlap in. A tool that meets Firebase in three rosters sits above one that meets it in a single roster, because more overlap means the comparison is more like-for-like.
The rationale under each entry is composed from the two tools' own cells. Where they differ on a field we score, the sentence names both values and the unit. Where they don't differ, it says so instead of manufacturing a distinction — which is why some entries are short.
Values, sources and verification dates all live on the category tables: Convex alternatives. If a figure here disagrees with a vendor's current pricing page, the vendor is right and we are stale.
Still deciding whether to move at all? The Firebase profile has the when-to-use and when-not-to-use blocks, and the Firebase timeline has the dated changes that usually trigger a migration.
