Best use cases
Implementation considerations
- Requires PHP 8.1+, Apache/Nginx with mod_rewrite, and standard PHP extensions (gd, mbstring, fileinfo, session, iconv); verify host support before deployment.
- Five writable folders (/cache, /content, /data, /media, /settings) must be configured correctly; incorrect permissions block functionality.
- Composer dependency management required; consider containerization (Docker image available on DockerHub) to standardize environments.
- No built-in backup strategy; implement file-based backup procedures for /content and /data directories outside the CMS.
- Plugin and theme ecosystem present but maturity unknown; audit custom code for security before production deployment.
When to avoid it — and what to weigh
- High-Concurrency Editorial Workflows — Flat-file architecture does not scale to large teams with simultaneous edits or require sophisticated access control beyond basic authentication.
- Content Requiring Complex Relational Data — No database means querying, joining, or managing interconnected content types is difficult; not suited for CMS-driven ecommerce or multi-tenant platforms.
- Mission-Critical Systems with SLA Requirements — Community-driven project with 606 stars and 51 open issues; no commercial support contracts or guaranteed response times are apparent.
- Dynamic Real-Time Content or Search at Scale — Flat-file indexing and search performance become bottlenecks at large document counts; not designed for real-time dynamic content.

Project provides a dedicated security contact ([email protected]) for vulnerability reporting, indicating some security awareness. No third-party security audits or CVE history visible in provided data. As with any self-hosted PHP CMS, server configuration, dependency updates, and folder permissions critically affect security posture. Review dependencies and keep PHP updated.
Alternatives to consider
Hugo
Static site generator; no server-side PHP required, better for high-traffic documentation and Git-native workflows, but lacks visual editor.
Sphinx + Read the Docs
Industry standard for technical documentation; stronger community, theming, and SEO support, but steeper learning curve and more complex deployment.
GitBook
Cloud-hosted markdown CMS with built-in eBook export; lower operational burden and team collaboration, but vendor lock-in and subscription costs.
