Zope

Zope is a long-established open-source web application server written in Python, first released in 1998 as the Z Object Publishing Environment. Its key strength is object publishing: URLs map directly to Python objects stored in the transactional ZODB object database, simplifying development of dynamic, content-rich sites with built-in persistence, fine-grained security, acquisition, and a through-the-web management interface. It serves site managers building quick content sites, developers creating custom reusable components, and administrators handling deployments. Still actively maintained by the Zope Foundation (with the 5.x series current and Zope 6 in progress as of 2025–2026), Zope remains a mature, reliable option for complex, maintainable web applications that prioritize data integrity and security over lightweight modern frameworks.
