Seaside is a free and open source web application framework for developing sophisticated web applications in Smalltalk.

Seaside provides a layered set of abstractions over HTTP and HTML that let you build highly interactive web applications quickly, reusably and maintainably. It is based on Smalltalk, a proven and robust language that is implemented by different vendors. Seaside includes:

  • Programmatic HTML generation
  • Callback-based request handling
  • Embedded components
  • Modal session management

Seaside also has good support for CSS and JavaScript, excellent web-based development tools and debugging support, a rich configuration and preferences framework, and more.

There are two free online books available that provide answers to most common questions:

Furthermore, the Seaside mailing-list is useful for more specific questions. Also check the mailing-list archive. Finally the website of Seaside itself is an excellent hub of links and other resources.
