Visit TrailBase

TrailBase is a single-executable backend built on Rust, Wasmtime, and SQLite, with experimental Postgres support. It provides type-safe REST and realtime APIs, a WebAssembly runtime for custom endpoints, geospatial support, SSR, built-in authentication, and an admin dashboard UI, designed for straightforward self-hosting across development, testing, and production environments.

It includes a built-in auth system supporting password-based and Social/OAuth sign-ups, realtime push-based data subscriptions, and access control via ACLs and SQL access rules. Clients and code-generation examples are provided for TypeScript, Dart/Flutter, Python, C#/.NET, and Rust, with JSON Schema used for type-safety. The admin dashboard UI is optional, allowing a config and migration-based setup instead.

TrailBase targets mobile, web, and desktop application developers who want a lightweight backend with minimal moving parts. It is packaged as a single executable available for Linux, MacOS, Windows, and Docker, with no separate editions or pricing tiers described.
