Hanami review
A focused Ruby framework for teams that want explicit, slice-based application structure.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Hanami is an open-source, full-stack Ruby web framework for building modular web applications and APIs. It combines application bootstrapping and command-line tooling with HTTP routing, action handlers, server-rendered views, templates, request validation, and parameter handling. Its slice-based organization is aimed at Ruby developers who want explicit boundaries between application components, whether working solo or across small, mid-market, or enterprise teams.
The framework’s architecture centers on isolated slices and the Hanami system’s dependency management and auto-injection. This gives teams a defined structure for composing application code while retaining server-side rendering through views and templates. Persistence is handled through integration with the ROM ecosystem rather than an included ORM, so teams evaluating Hanami should be comfortable selecting and configuring that persistence layer. The feature set stays focused on core web application concerns instead of bundling authentication or a broad collection of integrations.
Hanami is distributed free and open-source, with self-hosted deployment on infrastructure the team controls. The published support channel is documentation, making the available guidance centered on docs rather than a commercial support plan. Choose Hanami when modular Ruby architecture, built-in request handling, and server-rendered applications align with your project. Teams seeking bundled authentication, an included ORM, or deployment options beyond self-hosting should consider a framework whose core package covers those needs directly.

- Includes routing, views, validation, and dependency injection
