TrailBase is an open-source, single-executable Firebase alternative built on Rust, SQLite (with experimental Postgres support), and Wasmtime. It provides type-safe REST and realtime APIs, built-in authentication, an admin UI, a WebAssembly runtime for custom endpoints, geospatial support, and MCP integration with sub-millisecond latencies.

Use cases

• self-host a Firebase or Supabase alternative backend
• add auth and REST APIs to a mobile or web app without building a backend
• run a fast SQLite-backed backend as a single executable
• get realtime data subscriptions for a client-side app
• extend a backend with custom endpoints via WebAssembly
• replace a multi-service stack with one small deployable binary
• manage app data through an admin dashboard UI

When to choose

• you want a lightweight, self-hosted BaaS with relational SQL access
• you need sub-millisecond API latency without a separate cache layer
• you prefer a single binary that is easy to deploy and test
• you want built-in auth, file uploads, realtime, and admin UI out of the box
• you want full SQL access to the underlying database

When to avoid

• you need a battle-tested backend with years of production mileage
• you require managed hosting and vendor support
• you depend heavily on Postgres features (still experimental)
• you need a document store or serverless functions ecosystem like Firebase's
• your license requirements are incompatible with OSL-3.0
