What htmly is
A PHP 7.2+ CMS using file-based storage with custom indexing algorithms for content discovery by date, type, category, tag, and author. Requires PHP-Mbstring, PHP-XML, PHP-INTL, PHP-GD, and PHP-ZIP extensions; caching and content directories need write permissions.

Best use cases
Implementation considerations
- Requires manual deletion of install.php and online-installer.php post-setup; verify web root is not exposing these files.
- Write permissions required for cache and content directories; review file system permissions and ownership to avoid data loss or unauthorized access.
- PHP extension dependencies (Mbstring, XML, INTL, GD, ZIP) must be pre-installed on host; verify hosting provider supports all required modules.
- No built-in backup mechanism beyond ZIP extension; implement external backups for content and config.ini files.
- Admin access via /login endpoint; consider reverse proxy or WAF rules to protect admin panel from enumeration and brute-force attacks.
When to avoid it — and what to weigh
- High-Traffic Production Environment — No indication of caching layer, CDN integration, or horizontal scaling support. File-based indexing may bottleneck under heavy concurrent load.
- Complex Multi-Tenant or Enterprise Requirements — Flat-file architecture and role-based access (admin/user only) not designed for enterprise user hierarchies, audit trails, or compliance workflows.
- Team Collaboration at Scale — File locking, concurrent editing, and versioning controls are not addressed in documentation. Multiple simultaneous authors risk data conflicts.
- E-commerce or Transaction-Heavy Use Cases — No payment integration, inventory management, or transactional guarantees evident. Not suitable for shopping carts, subscriptions, or financial workflows.

Install and online-installer files require manual deletion post-setup; lingering files create admin panel exposure. Role-based access limited to admin/user; no granular permission model. File-based storage exposes content and config to file-system attacks if permissions misconfigured. No mention of input sanitization, CSRF protection, SQL injection (N/A for flat-file), XSS mitigations, or security audit history. Consider security review before production deployment.
Alternatives to consider
Statamic
Flat-file CMS with modern PHP (Laravel) stack, stronger API, better team collaboration features, and commercial support available.
Grav
Flat-file CMS with plugin ecosystem, better plugin architecture, and active maintenance; supports larger deployments and extensibility.
WordPress (lightweight config)
Database-driven but with caching layers (Redis, Memcached), mature security ecosystem, vast theme/plugin library, and large community support.
