Pico

Pico is a lightweight, file-based CMS written in PHP that requires no database setup. Development has been abandoned; the README explicitly recommends against new projects and suggests alternatives like Grav CMS, HTMLy, Automad, or Typemill.

What Pico is

Pico renders Markdown files to HTML via Twig templating, stores content and configuration in YAML, and runs on PHP 5.3.6+ with dom and mbstring extensions. The project is end-of-life with no active maintenance; compatibility with modern PHP versions is not guaranteed.

Quickstart

Get the Pico source

Clone the repository and explore it locally.

terminalbash
git clone https://github.com/picocms/Pico.gitcd Pico# follow the project's README for install & configuration

Best use cases

Legacy site maintenance

Keeping existing Pico sites running where no new features are needed and the hosting environment remains stable on compatible PHP versions.

Simple static documentation sites

Small documentation or knowledge-base projects with minimal interactivity, where flat-file storage and Markdown authoring reduce operational overhead.

Educational or proof-of-concept projects

Learning flat-file CMS architecture or demonstrating Markdown-to-HTML workflows in low-stakes environments without production requirements.

Implementation considerations

  • Verify PHP version compatibility on target server (5.3.6+ minimum, but modern PHP 7.x+ support is unknown—test thoroughly).
  • Confirm dom and mbstring PHP extensions are enabled; setup is manual and not validated by an installer.
  • Plan migration or contingency if hosting environment upgrades PHP versions; no upgrade path documented for Pico itself.
  • Flat-file storage means no built-in backup, version control, or concurrent editing—implement external versioning (Git) if needed.
  • Review existing site for custom plugins or themes; these may not be maintained or compatible with future PHP upgrades.

When to avoid it — and what to weigh

  • Starting a new production site — Project maintainers explicitly warn against using Pico for new websites. No active development, security patches, or modern PHP compatibility roadmap.
  • Requiring modern PHP (7.x+) — Designed for PHP 5.3.6+; compatibility with current PHP versions (8.0+) is unclear and untested. Upgrading existing infrastructure may break the installation.
  • Need for active support or community — Development has stopped; no maintainers actively respond to issues. Community support is minimal. An abandoned project carries technical debt and security risk over time.
  • Scalability or enterprise features — Flat-file architecture and lack of indexing make it unsuitable for large content libraries, multi-user workflows, or complex permission models.

License & commercial use

MIT License (OSI-approved, permissive). Allows commercial use, modification, and distribution with minimal restrictions, provided the license and copyright notice are retained.

MIT is a permissive OSI license that permits commercial use. However, given the project's end-of-life status and lack of active maintenance, commercial reliance is not recommended. Liability for security issues, compatibility failures, or performance problems rests entirely with the deployer. Requires independent risk assessment and support planning.

Security considerations

README states "no known security issues" but provides no detail on threat model, penetration testing, or vulnerability disclosure process. Given end-of-life status, no security patches are planned. Projects depending on Pico should conduct independent code review and supply-chain risk assessment. Flat-file storage reduces certain database-attack vectors but introduces file-system and PHP execution risks. Regular backups and access controls are operator responsibility.

Alternatives to consider

Grav CMS

Active flat-file CMS with modern PHP support, plugin ecosystem, and ongoing development. Recommended by Pico maintainers as a direct upgrade path.

Hugo

Fast, compiled static site generator with Markdown support. No runtime PHP requirements, lower operational overhead, and strong community.

11ty (Eleventy)

Modern JavaScript-based static site generator with flexible templating and active maintenance. Better suited for new projects prioritizing ease of use and extensibility.

Pico FAQ

Is Pico still secure for production use?
Pico has no known reported security issues, but is no longer maintained. Security patches are not planned. Independent code review and ongoing monitoring are required if deployed in production.
Will Pico work on modern PHP versions (7.x, 8.x)?
Unknown. Pico was designed for PHP 5.3.6+. Compatibility with PHP 7.x and 8.x is not clearly documented or tested. A v3.0.0-alpha.2 release exists but was abandoned mid-cycle.
Can I contribute to Pico or take over maintenance?
Possibly. The README invites new maintainers via GitHub Issues. Interested parties should provide commitment extent, motivation, and experience with Pico, PHP, and Open Source development.
What is the upgrade path from Pico 2.x?
Limited. v3.0.0-alpha.2 and the pico-3.0 branch exist as development versions but are unstable and did not reach stable release. No official migration guide. Evaluating alternatives (Grav, Hugo, 11ty) is recommended for new projects.
