## What it is
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
