Top Supabase Alternatives in 2026

Firebase is Google's answer to the same problem Supabase solves: bundling a database, auth, storage, and serverless functions so you don't stand up each piece yourself. The big difference is the data model. Firestore is NoSQL, so teams used to Supabase's real Postgres and SQL joins have to denormalize data instead. Pricing works differently too. There's no flat plan fee, just a free Spark tier with fixed daily quotas and a pay-as-you-go Blaze plan that bills per read, write, and byte of bandwidth once you cross them. That makes Firebase the strongest pick for mobile-first teams, since its Android, iOS, and Flutter tooling is more mature than Supabase's, and Cloud Messaging push notifications stay free at any volume. The tradeoff is that Firebase only runs on Google Cloud, with no self-hosted option and no path to move your backend elsewhere later.

Appwrite covers the same bundle as Supabase: auth with MFA and OAuth, a database, file storage, serverless functions, and realtime subscriptions, all under one SDK set. Where it splits from Supabase is the data model and the deployment story. Appwrite's database is document-based rather than SQL, and like Supabase its core server is open source and free to self-host in full. The real difference is what happens if you move off self-hosting later: Appwrite Cloud uses the same SDKs, so you can start on your own server and switch to managed hosting without a rewrite. Cloud pricing is also transparent below Enterprise. Free covers 2 shared projects, and Pro is $25 a month per project for dedicated resources, with published overage rates for bandwidth, storage, executions, and active users instead of a sales call. The catch is that every one of those resource types bills separately, so a busy app can rack up several overage lines on one invoice, much like Supabase's own bill has many moving parts.

Nhost is the closest architectural match to Supabase on this list: a managed Postgres database, built-in auth, file storage, and serverless functions, with a Hasura-compatible GraphQL API as the primary interface. Supabase auto-generates a GraphQL API too, through its pg_graphql extension, but that's a bolt-on layer sitting on top of RLS-first REST, not a first-class engine with the permissions and relationships tooling Nhost's Hasura layer gives you. Billing runs per organization rather than per project, so several small apps can share one Pro plan's pool of database, storage, egress, and compute, which suits teams running multiple projects under one account, unlike Supabase's per-project billing. The tradeoff is a steep jump to Team at $599 a month for SOC 2 and support SLAs, mirroring Supabase's own Free-to-Team gap, and Nhost's newer Constellation GraphQL engine only shipped in alpha in mid-2026, still missing some Hasura features like event triggers.

Convex trades Supabase's SQL-first model for a TypeScript-first one. Instead of writing queries against Postgres, you write server-side functions against Convex's own reactive database, and the frontend updates automatically when underlying data changes with no subscription code to write. Its free tier has no time limit, covering 1M function calls and half a gigabyte of database storage a month, generous in the same spirit as Supabase's own free plan. Professional pricing is $25 per developer per month plus metered usage past included quotas, a per-seat model rather than Supabase's per-project fee. Convex fits teams building fresh rather than migrating an existing SQL schema, since there's no direct Postgres access to fall back on. Business plans start at a steep $2,500-a-month minimum, and Enterprise pricing stays a custom quote, similar to how Supabase's own top tier needs a sales conversation.

PocketBase strips the Supabase idea down to its smallest possible footprint: one Go binary that runs an embedded SQLite database, built-in auth with OAuth2 providers, file storage, realtime subscriptions, and an admin UI, with no external services to wire up. It is free and MIT licensed with no paid tier at all, unlike Supabase's flat-fee-plus-usage billing, since you only pay for whatever server you run it on. That makes it the pick for solo developers and small projects that want to skip building auth and storage from scratch without taking on any platform bill. The tradeoffs are real. It runs as a single instance on one SQLite file with no horizontal scaling path, the project is maintained largely by one person, and its own docs say it isn't recommended yet for production-critical apps without care around migrations between versions.
