PmWiki

PmWiki is a wiki-based content management system focused on collaboratively creating and maintaining websites. It provides page editing through a simple markup syntax, with optional restrictions for who can read, edit, or upload content.

Key Features

• In-page editing workflow with simple markup (no need to write HTML for typical edits)
• Skins and templates to change site look-and-feel
• Granular, page/group/site-level password protection for reading, editing, and attachments
• File attachments and uploads with configurable permissions
• Extensible architecture with a large collection of community extensions ("recipes")
• Can integrate with external authentication sources (e.g., web server auth, LDAP, databases)

Use Cases

• Team or project documentation wiki with role-based access
• Lightweight intranet knowledge base with per-page permissions
• Public community site where trusted editors maintain pages

PmWiki is a mature, lightweight option for organizations that want a customizable wiki-style CMS with strong built-in access control and a flexible extension ecosystem.
