Ultimo combines the raw performance of Rust with the developer experience of modern full-stack frameworks. Type safety, automatic client generation, and production-ready features out of the box.
Ultimo matches Axum's performance with 152k+ requests per second and sub-millisecond latency. Built on proven foundations like Hyper and Tokio, you get raw Rust speed without compromise.
Define your API once in Rust and get fully typed TypeScript clients automatically. No more manual type syncing, API drift, or runtime errors from mismatched types.
Generate OpenAPI 3.0 specifications directly from your Rust code. Integrate with Swagger UI, Postman, and any OpenAPI-compatible tool ecosystem.
Support both traditional REST endpoints and efficient JSON-RPC procedures in the same application. Choose the right paradigm for each use case without architectural compromises.
Authentication, authorization, CORS, rate limiting, and request validation are included out of the box. Focus on building features, not security infrastructure.
Ergonomic APIs, helpful error messages, comprehensive CLI tools, and excellent documentation. Designed to make you productive from day one.
Works seamlessly with SQLx, Diesel, SeaORM, or any Rust database library. Use your preferred ORM or go with raw SQL—Ultimo doesn't lock you in.
Deploy anywhere Rust runs: traditional servers, containers, edge computing, or serverless. Compile to a single binary with no runtime dependencies.
Compose behavior with a powerful, type-safe middleware system. Built-in middleware for common tasks, easy to write custom middleware.
CLI tools for project scaffolding, development server with hot reload, built-in testing utilities, and deployment helpers.
Plugin system for extending functionality. Works with the entire Rust ecosystem. Add any crate without fighting the framework.
Built to handle everything from prototypes to high-traffic production systems. Efficient memory usage, connection pooling, and request pipelining.
Join developers building faster, safer, and more maintainable applications with Ultimo.
