Appwrite alternatives (2026)
Appwrite: A complete Firebase-style backend you can actually self-host — worth it if you want one SDK for auth, data and files.
Its Catch: Self-hosted Appwrite is a stack of many Docker containers, so plan for upgrades, backups and monitoring yourself; major-version upgrades have migration steps.
Below: 8 free or free-tier tools from the same category (Next.js app platform tools), free and open source first, then the closest match by shared tags. Each keeps its own Catch.

VerdictPick it over Supabase if you want GraphQL-first Postgres.
CatchThe GraphQL API runs on Hasura, so you inherit Hasura's permission model. Self-hosting the whole stack in production is possible but the hosted Nhost platform (free tier plus paid plans) is the main path. Smaller community than Supabase.
Free / OSS · OSS/MIT · 35.9k GitHub stars
VerdictA strong code-first base for React internal tools.
CatchThe company now also promotes an AI agent product, and core releases have slowed since April. The abstractions take time to learn, and you still write all the UI code.
Free / OSS · OSS/MIT · 608 GitHub stars
VerdictMIT Rust React builder. Reach for it when parallel agent/CI builds make Vite’s memory cost the bottleneck.
CatchVs Vite (default SPA/library toolchain) and Rolldown/Oxc-adjacent Rust tooling: OJ is the agent/CI-memory-oriented React builder, not the ecosystem default yet. Young Lovable Labs surface — verify plugin compatibility before you rip Vite out of a production app.
Free / OSS · Apache-2.0 · 14.7k GitHub stars
VerdictThe default way to use IndexedDB without pain — add your own sync or Dexie Cloud.
CatchSync, auth and collaboration come from Dexie Cloud, a separate commercial service; the library itself is local only. IndexedDB storage can be evicted by the browser under storage pressure unless you request persistence. Queries are index-based, not SQL.
Free / OSS · OSS/MIT · 36.7k GitHub stars
VerdictStill a solid pick for NestJS-style apps — newer projects often prefer Drizzle.
CatchDecorators and reflection metadata feel heavy next to schema-first tools like Drizzle or Prisma, and type safety for complex queries is weaker. Maintenance went through quiet years before the 1.x releases, so some old issues linger. Lazy relations and migrations need discipline.
Free / OSS · Apache-2.0 · 10.6k GitHub stars
VerdictA great zero-server search library for docs and small catalogs.
CatchThe index lives in memory in your process, so it fits small to medium datasets, not millions of large documents. The last release was December 2025 and the last code change July 2026, so the open-source library moves slowly while the company focuses on Orama Cloud. GitHub does not detect the license; the LICENSE.md text is Apache-2.0.
Free / OSS · OSS/MIT · 4.1k GitHub stars
VerdictThe simplest secure session layer for a Next.js app.
Catchv9 requires Node 22.13+ and is ESM-only, so upgrading from v8 needs code changes. Cookies cap out at about 4 KB, so store IDs, not big objects. Stateless sessions cannot be revoked server-side without extra bookkeeping. It manages sessions; login, OAuth and passwords are up to you.
Free / OSS · OSS/MIT · 13.1k GitHub stars
VerdictThe default toast choice for modern React apps.
CatchOpinionated by design: heavy visual customization means fighting the defaults. React only. Releases are occasional.
