Oddmuse

Oddmuse is a compact wiki engine implemented as a Perl script that stores pages directly on the filesystem rather than in a database. It is designed for small to medium wikis, provides built-in versioning and a simple, extensible architecture, and can run under traditional CGI or as a Mojolicious-based server.

Key Features

• Single-file core: the wiki is delivered as one primary Perl script with optional extension scripts and configuration files
• Filesystem storage: pages and revisions are stored on the local filesystem; no database required
• Built-in versioning and history for pages, including simple restore capabilities
• Runs under CGI (e.g., Apache) or as a Mojolicious server (including Hypnotoad for production)
• Extensible via Perl modules, themes (CSS) and configuration scripts; supports translations
• Small footprint and cross-platform compatibility (Unix-like systems, Windows, many hosting providers)

Use Cases

• Internal team or project documentation hosted on inexpensive/shared hosting
• Lightweight public or community wikis where simplicity and small resource usage are priorities
• Quick knowledge bases or help sites that require versioned pages without a database backend

Limitations and Considerations

• Older, Perl-centric codebase; maintaining or extending core features typically requires Perl knowledge
• Lacks many modern integrated features (real-time collaboration, built-in WYSIWYG editor, advanced plugin ecosystem)
• Filesystem storage can limit scalability and advanced querying compared to database-backed wikis

Oddmuse is a minimal, pragmatic choice for sites that prioritize simplicity, low resource usage, and filesystem-based versioning. It is best suited for users comfortable with Perl and simple CGI or Mojolicious deployment models.
