description Seaside Overview

Seaside is an open-source web development framework primarily written in Ruby that emphasizes convention over configuration and promotes clean, maintainable code through its Model-View-Controller architecture.

help Seaside FAQ

Is Seaside a Ruby framework like Ruby on Rails?

No, Seaside is a web framework written in Smalltalk, not Ruby. Unlike Rails and its conventional MVC request flow, Seaside is known for stateful components and continuation-based handling of user interactions.

Which Smalltalk environments can run Seaside?

Seaside has been used with Smalltalk systems including Pharo, Squeak, and GemStone/S. The exact installation process and available packages depend on the selected Smalltalk image.

What do continuations do in a Seaside application?

Continuations let application code suspend a workflow, display a page or component, and later resume with the user's response. Seaside's call-and-answer pattern can therefore express a multi-page interaction more like ordinary sequential Smalltalk code.

How does Seaside prevent broken browser back-button behavior?

Seaside tracks component and session state and generates callbacks tied to rendered pages. Developers still need to understand session lifetime and external side effects, but the framework was explicitly designed around stateful web interactions.
