Overview
FlatPress is a free, open-source blogging engine built in PHP that stores all content in flat files instead of a database. First released in 2006, it was designed for hosting environments without reliable database access and has been maintained by a volunteer community ever since, released under the GNU GPLv2 license.
The project borrows conceptually from WordPress in its plugin and hook system, while keeping its own footprint intentionally small: no database server to install or maintain, and a backup process that amounts to copying a single directory.
Key Features
Core capabilities include flat-file content storage with no database dependency, Smarty-based theming for separating design from application logic, a plugin and widget system for extending functionality, and a web-based admin panel for writing posts and managing comments and pages.
FlatPress supports PHP 7.2 through 8.5, ships with translations in more than twenty languages, and includes built-in comment spam mitigation, making it usable on minimal shared-hosting plans.
Pricing
FlatPress is entirely free and open source under GPLv2, with no paid tiers, subscriptions, or official managed hosting offering. The only ongoing cost is whatever web hosting the operator chooses to run it on.
Support comes from the project's documentation wiki, GitHub issue tracker, and community forums rather than a commercial vendor support desk.
Key Features
Flat-file content storage — Posts, comments, and configuration are stored as files on disk instead of in a database, simplifying hosting and backups.
Smarty templating — Themes are built with the Smarty templating engine, cleanly separating design from application code.
Plugin and widget system — A WordPress-inspired hook architecture lets developers extend posting, commenting, and rendering behavior.
Web-based admin panel — Write posts, manage pages, and moderate comments entirely through a browser-based dashboard, no SQL required.
Multi-language interface — Ships with community-contributed translations covering more than twenty languages.
Built-in comment spam protection — Includes native tooling to reduce spam on blog comments without third-party services.
Simple backup and migration — Because all data lives in one directory, backing up or moving a site is as simple as copying files.
Broad PHP compatibility — Runs on Apache, Nginx, or IIS with support for PHP versions from 7.2 through 8.5.

Frequently Asked Questions
Is FlatPress free to use?
Yes. FlatPress is fully open source under the GNU GPLv2 license, with no paid tiers or subscription fees.
Does FlatPress require a database?
No. FlatPress stores all posts, comments, and settings as flat files, so no MySQL or other database server is needed.
What server requirements does FlatPress have?
FlatPress runs on Apache, Nginx, or IIS with PHP 7.2 through 8.5, and needs no separate database service.
Is FlatPress still actively maintained?
Yes. The project continues to release updates on GitHub, with version 1.5.1 as its most recent stable release.
How do I back up a FlatPress site?
Because all content lives in files rather than a database, a full backup is as simple as copying the site's directory.
Is FlatPress a good choice for large, high-traffic websites?
FlatPress works best for personal or small blogs; the flat-file model is well tested at moderate content volumes but is not optimized for very large, high-traffic publications the way a database-backed CMS is.
