TrailBase

TrailBase is a modern, open-source backend-as-a-service that combines a realtime SQLite database, type-safe REST APIs, authentication, a WebAssembly runtime, and an admin dashboard into a single Rust executable. Positioned as a self-hosted alternative to Firebase and Supabase, TrailBase emphasizes raw performance — its maintainers report it is roughly 11x faster than PocketBase and nearly 40x faster than Supabase for typical CRUD workloads — and operational simplicity, since the entire backend ships as one process with no external database to manage. The project is actively developed on GitHub and licensed under OSL-3.0.

Common Use Cases

Indie developers and small teams use TrailBase to ship web and mobile applications without standing up a separate Postgres or MySQL instance, relying on auto-generated REST and realtime APIs to power their frontends. Mobile developers integrate it as the backend for Flutter, Swift, or Kotlin apps using the official client SDKs, getting authentication, data sync, and push-style realtime updates without writing custom endpoints. Backend engineers extend TrailBase with custom logic by writing WebAssembly components in JavaScript, Rust, or Go, embedding business rules close to the data without restarting the server. Platform teams adopt TrailBase as a prototyping layer for internal tools and admin dashboards, taking advantage of the bundled admin UI to model collections and configure access policies through a browser.

Key Features

• Type-safe REST APIs auto-generated from SQLite collections, with JSON Schema for every record type
• Realtime subscriptions that push record changes to connected clients without polling
• Built-in WebAssembly runtime (Wasmtime) for sandboxed custom server-side logic
• JWT-based authentication with refresh tokens and email/password sign-up
• OAuth2 login support for Google, Discord, and other providers
• Admin dashboard for managing tables, records, auth providers, and access rules
• SQLite-backed storage with sub-millisecond query latency and no external database service
• Client SDKs for TypeScript, Dart/Flutter, Python, C#/.NET, Rust, Go, Swift, and Kotlin
• TanStack/db integration for synchronized client-side state
• Single-binary deployment with a minimal Alpine-based container image
• Schema migrations and JSON Schema export for integrating with code generators
• CLI for managing users, admins, components, and migrations from the terminal

Why deploy TrailBase on Hostinger VPS

Deploying TrailBase on a Hostinger VPS gives you dedicated CPU and memory for a Rust backend that thrives on consistent low-latency performance, with no cold starts and no per-request fees from a commercial BaaS. Because TrailBase stores data in SQLite on the local disk, VPS storage performance translates directly into faster API responses, while the named Docker volume keeps your database, configuration, and auth state safe across container updates. Full root access lets you tune resource limits, attach external backups, and integrate TrailBase with the rest of your VPS stack — from reverse proxies to monitoring tools. Self-hosting also means user records, refresh tokens, and application data never leave infrastructure you control, an important property for teams subject to data residency or compliance requirements.
