Agile software development values individuals and interactions over processes, working software over comprehensive documentation, customer collaboration over contract negotiation, and responding to change over following a plan. Seaside is an agile web framework that values these principles by having motivated individuals interact through mailing lists and meetings, releasing working software in short iterative cycles, collaborating directly with customers on its open source mailing list, and evolving its features, libraries, and platforms over time in response to changes.
