Typemill

Typemill is a lightweight, open-source flat-file CMS designed for documentation, manuals, knowledge bases and eBook publishing. It stores content as Markdown/YAML files, provides an author-friendly editor and a plugin/theme system for extensions and custom layouts.

Key Features

• Flat-file content storage using Markdown and YAML (no database required).
• Author-friendly visual block editor plus raw Markdown editing and versioning tools.
• eBook generation (PDF and EPUB) via an eBook plugin and customizable layouts.
• Built with Slim PHP core, Vue.js frontend components and Tailwind CSS; Twig templates and Symfony event dispatcher are used for theming and extensibility.
• Media library, user management, access control and an optional REST API for integrations.
• Kixote: a conversational/command-style AI interface for authoring and admin commands; supports external AI providers via API keys.
• Plugin and theme ecosystem (free and paid), plus a demo installation for testing.

Use Cases

• Producing and publishing product manuals, technical documentation, and company handbooks.
• Building knowledge bases or help centers for small to mid-sized teams and organizations.
• Creating publication projects or small eBook catalogs with single-source publishing (website + PDF/EPUB).

Limitations and Considerations

• Requires PHP 8.1 or higher and typical PHP extensions (gd, mbstring, fileinfo, session, iconv); some plugins (e.g., eBook features) may require extra extensions like php-xml or php-zip.
• Advanced full-text search and certain theme/plugin features may require paid MAKER/BUSINESS licenses or installing specific plugins (e.g., Bettersearch for full-text search).

Typemill provides a focused, extensible platform for structured documentation and publishing workflows, balancing a small footprint with plugin-driven capabilities. It is suitable for teams that prefer Markdown-first content and want self-hosted control with optional premium plugins for advanced features.
