FastSchema review
An open-source, self-hosted backend for relational CRUD APIs and realtime data.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
FastSchema is an open-source Backend as a Service and Go web framework for developers building dynamic web applications. It centers backend development on schemas, then generates database tables, CRUD REST APIs, OpenAPI documentation, and an administrative dashboard. The product can run as a standalone self-hosted backend or be embedded in a Go application, making it a fit for teams that want control over deployment and a relational data model rather than a purely hosted backend service.
Its main strength is the breadth of backend capabilities connected to the schema layer. FastSchema supports realtime record updates over WebSockets, JWT authentication with local, social OAuth, and OTP options, role-based access control, file uploads, and storage integrations. The published integration options include S3-compatible storage, GitHub OAuth, and Google OAuth. The admin dashboard covers content and user management, while JavaScript and Go plugins provide extension points for teams working in those ecosystems. A JavaScript SDK is also included for application integration.
FastSchema is most appropriate when generated CRUD APIs, relational modeling, authentication, permissions, storage, and realtime updates need to sit in one self-hosted backend. Its open-source model and free self-hosting make it accessible without a paid entry tier, while its Go framework support suits projects already using Go. Choose an alternative if your application needs a different database model, a broader plugin language range, or a hosted service rather than a self-managed deployment. For schema-driven web applications that value generated APIs and direct control of the backend environment, FastSchema offers a focused set of connected building blocks.
