appwrite vs spacetimedb
Two of the top projects in Backends and databases, side by side: who leads on each score part and who each one suits, then setup, license, activity and what each review found.
appwrite
Self-hostable backend with auth, databases, storage, functions, messaging and hosting
spacetimedb
Relational database that runs your app logic as modules and syncs clients live
Verdict
appwrite ranks higher, 93 to 66. Of the 5 score parts we measure for both, appwrite leads on 4, spacetimedb on none and 1 is even.
- Adoptionappwrite leads by 30 points, 87 to 57: a wide gap.

Pick appwrite if you are
Developers who want a self-hosted or managed backend for web and mobile apps
- One Docker-based installer sets up the full stack, with Compose and env files also published
- SDKs for 6 client and 10 server platforms, plus REST, GraphQL and Realtime APIs
Pick spacetimedb if you are
Developers building realtime web apps or multiplayer games, no separate server
- Replaces the API server and pub/sub layer: clients subscribe to tables and get pushed updates
- Module languages: Rust, C#, TypeScript, C++; client SDKs include React hooks, Unity and Unreal

appwrite
Appwrite is a backend platform that bundles Auth, Databases, Storage, Functions, Sites, Messaging, Realtime and a Firewall behind REST, GraphQL and WebSocket APIs. It runs as a managed cloud or self-hosted via a Docker installer, and offers a hosted MCP server so coding agents can operate on a live project. Client and server SDKs cover Web, Flutter, Apple, Android, React Native, Unity, Node.js, Python, PHP, Go, Rust and others.
Who it is for: Developers who want a self-hosted or managed backend for web and mobile apps
Strengths
- One Docker-based installer sets up the full stack, with Compose and env files also published
- SDKs for 6 client and 10 server platforms, plus REST, GraphQL and Realtime APIs
- Hosted MCP server uses OAuth, so no API keys are needed on Cloud
- Same product runs on managed Cloud or on your own infrastructure
Weaknesses
- Installer needs access to the Docker socket on the host
- Self-hosted instances must use a separate local MCP server, not the hosted one
- Hybrid monolith-plus-workers architecture means many services to operate
- RAM and CPU requirements are not stated in the README
- no GPU
- Docker + Compose
- Needs Docker
- port 20080
spacetimedb
SpacetimeDB is a relational database that doubles as the application server. You write tables and reducers as a module in Rust, C#, TypeScript or C++, upload it, and clients connect directly, subscribe to tables and receive committed changes automatically. State is held in memory with an on-disk commit log for durability, and reducers run as ACID transactions.
Who it is for: Developers building realtime web apps or multiplayer games, no separate server
Strengths
- Replaces the API server and pub/sub layer: clients subscribe to tables and get pushed updates
- Module languages: Rust, C#, TypeScript, C++; client SDKs include React hooks, Unity and Unreal
- Reducers are ACID transactions; confirmed reads wait for commit log durability by default
- Used for the full backend of the MMORPG BitCraft Online
Weaknesses
- BSL 1.1 license, converting to AGPL v3.0 with linking exception after a few years
- Aimed at low-latency transactional workloads, not batch or analytical queries
- Application logic lives inside the database, tying the app to its module model
- RAM requirements are unknown, though all application state is held in memory
- no GPU
- Docker + Compose
- port 3000
