Plone

Plone is a mature, security-focused content management system (CMS) for building websites, intranets, and content-rich applications. It emphasizes structured content, fine-grained permissions, editorial workflows, and long-term maintainability, and can be used as a traditional CMS or as a headless backend.

Key Features

• Granular role-based access control and per-object permissions
• Editorial workflows (review/publish), versioning, and audit-friendly content governance
• Structured content types with schema-driven fields and validation
• Rich text editing, media handling, and reusable content components
• Search and navigation features for large content collections
• Headless delivery options (REST/JSON APIs) alongside classic server-rendered UI
• Extensible add-on ecosystem and theming for custom sites
• Security track record with coordinated security releases and hardening guidance

Use Cases

• Public-facing websites for organizations needing strong governance and permissions
• Intranets/extranets with departmental content ownership and review processes
• Headless CMS backend for custom frontends while retaining editorial tooling

Plone is well-suited for teams that need robust permissions and workflows, predictable upgrades, and an extensible Python-based platform for managing structured content at scale.
