Supabase alternatives for developers who want options

By Gerald · 11 June 2026

Connected network nodes representing backend platform options

Supabase is not the only way to get a modern backend with auth, database, and realtime features. It is a strong option, especially if you want Postgres. But if you are evaluating it, you should also know what you are giving up by not looking elsewhere. The right backend depends on what your product actually does, not on which platform has the most GitHub stars.

There is no best backend for every app. There is only the backend whose tradeoffs match the product you are building and the team you have.

Why developers look beyond Supabase

Some teams leave Supabase because they need a more opinionated platform that makes decisions for them. Others leave because they want a different database model, a reactive query system, or a backend that stays in TypeScript from client to server. Some simply outgrow the free tier and discover that another platform handles their traffic shape more cheaply.

The honest reason to evaluate alternatives is not that Supabase is flawed. It is that your app may have needs that another backend serves better.

The alternatives at a glance

Multiple server paths branching from a central hub — Each backend alternative solves a different problem. The right one depends on what you actually need.

	Database	Best for	Lock-in level	Self-hosting
Convex	Document-relational	Reactive TypeScript apps	Medium	Open source backend
Firebase	NoSQL document store	Mature ecosystem, mobile apps	High	No
PlanetScale	Serverless MySQL	SQL with branching deploys	Low	No
Appwrite	Multiple backends	Open-source all-in-one backend	Medium	Docker
Neon	Serverless Postgres	Standard Postgres, scale to zero	Low	No

Convex: reactive TypeScript backend

Convex is the alternative closest to Supabase in ambition but farthest in approach. It offers a document-relational database, reactive queries, TypeScript functions, and built-in realtime behavior. Queries automatically update when data changes. Mutations are transactional by default.

Convex suits React and TypeScript teams building live products where screens must stay current without manual refresh logic. I built Flow on Convex because notes, tasks, and captures need to sync across devices instantly. Convex made that behavior part of the query model rather than a feature I had to wire up.

The tradeoff is that Convex is not SQL, not Postgres, and not as broadly known. Ecosystem size and hiring pool are smaller. Pricing at scale requires careful modeling. The free tier is generous and does not pause projects for inactivity, which matters for side projects.

Firebase: the mature ecosystem

Firebase has been around longer than almost every alternative on this list. It offers a NoSQL document database, authentication, hosting, cloud functions, analytics, and a massive ecosystem of integrations and documentation.

Firebase suits teams that want a proven platform with broad platform support, especially for mobile apps. The realtime sync is powerful, though less typed than Convex. The ecosystem is hard to beat. If you need crash reporting, push notifications, A/B testing, and analytics in one place, Firebase is still the standard.

The tradeoff is vendor lock-in. Firebase is deeply Google. There is no self-hosting path, and migrating away means rewriting around a different data model. The free tier is generous, but costs can climb quickly at scale. The NoSQL structure also means you must design your data model carefully to avoid expensive queries.

PlanetScale: serverless MySQL

PlanetScale offers serverless MySQL with branching deploys, deploy requests, and a developer-focused workflow. It is a database service rather than a full backend platform, but it pairs well with frameworks like Next.js or separate auth providers.

PlanetScale suits teams that want SQL, branches for schema changes, and a modern database workflow without managing servers. The branching model is genuinely useful for teams that deploy frequently. You can branch your database schema, test changes, and merge them into production through a deploy request.

The tradeoff is that PlanetScale is only the database. You still need to build or buy auth, storage, realtime, and serverless functions elsewhere. It is a strong piece of infrastructure, not a complete backend.

Appwrite: open-source all-in-one

Appwrite is an open-source backend platform that offers auth, database, storage, and functions. It is designed to be self-hosted through Docker and gives you full control over your infrastructure.

Appwrite suits teams that want an open-source, self-hosted backend without paying per-seat or per-request fees to a cloud provider. The community is active and the feature set is broad. You get auth, databases, storage, and functions under one open-source roof.

The tradeoff is operational effort. Self-hosting means you are responsible for updates, scaling, and reliability. The ecosystem is smaller than Firebase or Supabase. You also need to manage the server or cluster that runs Appwrite, which adds DevOps work that managed platforms handle for you.

Neon: serverless Postgres

Neon is serverless PostgreSQL with scale-to-zero, branching, and a modern developer experience. It is closer to PlanetScale in shape than to Supabase: it is a database service, not a full backend platform.

Neon suits teams that want standard Postgres with automatic scaling and cost efficiency for low-traffic periods. The scale-to-zero model can save money for apps with irregular usage patterns. When no one is using the app, the database scales down and stops billing for compute.

The tradeoff is the same as PlanetScale. Neon is the database layer. Auth, storage, and application logic live elsewhere. If you want a complete backend in one platform, Neon is only part of the answer.

Pricing at a glance

Pricing models differ enough that a direct comparison is tricky, but the patterns matter.

Platform	Free tier strength	Paid model	Best for budgets
Convex	Generous, no pause	Per developer plus usage	Small teams, dev-heavy
Firebase	Generous	Usage-based, can spike	Variable traffic
PlanetScale	Limited	Per compute and storage	Predictable SQL workloads
Appwrite	Self-hosted is free	Infrastructure you manage	Teams with ops capacity
Neon	Generous	Scale-to-zero compute	Irregular traffic
Supabase	Generous, may pause	Per org plus compute	Standard Postgres needs

The cheapest option depends on your traffic shape, not the headline price. A side project with zero users is free on almost every platform. A product with 10,000 daily active users and heavy database writes will see real bills on all of them.

How lock-in differs across platforms

Lock-in is not binary. It is a spectrum.

Firebase has the highest lock-in. Your data, auth, and functions live in a Google-owned platform with no self-hosting path. Moving away is a migration project.

Convex has medium lock-in. The backend is open source and self-hostable, but your app logic is written in Convex functions with Convex client libraries. Exporting data is possible. Moving the app is a rewrite.

Supabase, PlanetScale, and Neon have lower lock-in because your data is in standard SQL databases. You can export a Postgres or MySQL dump and import it elsewhere. The platform tooling is proprietary, but the data is portable.

Appwrite has medium lock-in on features but low lock-in on hosting because you control the infrastructure. Moving away means replacing features, but you own the deployment.

How to choose

Pick Convex if you are building a reactive TypeScript app and want live updates, typed functions, and fewer backend decisions.

Pick Firebase if you need a mature ecosystem, broad mobile support, and you are comfortable with Google Cloud lock-in.

Pick PlanetScale if you want serverless MySQL with branching deploys and you are happy to assemble the rest of your backend separately.

Pick Appwrite if you want an open-source, self-hosted all-in-one backend and you have the operational capacity to run it.

Pick Neon if you want serverless Postgres with scale-to-zero and you will handle auth and application logic through other tools.

Pick Supabase if none of those specific strengths outweigh your need for standard Postgres, row level security, and the widest database ecosystem.

Frequently asked questions

What is the best Supabase alternative? There is no single best alternative. Convex is better for reactive TypeScript apps. Firebase is better for mature mobile ecosystems. PlanetScale and Neon are better for serverless SQL. Appwrite is better for self-hosted open-source backends.

Is Convex better than Supabase? Convex is better for reactive TypeScript products where live screen updates are central. Supabase is better when you need Postgres, SQL, row level security, and standard database tooling.

Should I use Firebase instead of Supabase? Use Firebase if you value ecosystem maturity and broad platform support over SQL and data portability. Use Supabase if you want a relational database with modern APIs.
