HTMLy is a free, open-source, databaseless PHP blogging platform. See 2026 features, pricing, pros, cons, and alternatives for flat-file CMS users.
HTMLy is a free, open-source blogging platform that stores every post as a flat text file rather than relying on a database, giving it a lightweight footprint that runs comfortably on inexpensive shared hosting. It is built in PHP by a developer known as DanPros and distributed under the GPL v2 or later license through a public GitHub repository.
The platform's databaseless design is its defining characteristic: there is no MySQL or PostgreSQL instance to install, configure, or secure, which simplifies both setup and ongoing maintenance for site owners who don't want to manage a separate database server.
Because there is no company or funding history behind HTMLy, it operates purely as a community-maintained open-source project, with development activity, releases, and support happening through GitHub issues and the project's own site rather than a commercial support organization.
HTMLy supports the core features expected of a blogging platform, including archives, categories, tags, automatic sitemap generation, and full-text search, all built on top of a custom file-indexing algorithm designed to stay fast even as a site grows to tens of thousands of posts.
Security and workflow features include two-factor authentication for the admin panel, scheduled post publishing, custom fields for extending content metadata, and a menu editor that updates site navigation with a single click.
Because HTMLy requires no database, backups are as simple as copying the site's files, and the platform includes built-in backup functionality via the PHP ZIP extension, further reducing the operational overhead compared to database-driven CMS platforms.
HTMLy is entirely free and open source under the GPL v2 or later license, with no paid tiers, subscriptions, or premium feature gates. Anyone can download the source code from GitHub or use the online installer at no cost.
The only ongoing expense is web hosting, and because HTMLy has minimal server requirements, running only PHP 7.2 or higher without a database, it can operate on very inexpensive shared hosting plans or even free hosting tiers that support basic PHP, making the total cost of ownership close to zero for most users.
