SPIP

SPIP Review: Features, Installation and Benefits

SPIP, standing for “System for Publishing on the Internet”, is a free, open‑source content‑management software designed to publish and manage websites. The project places special emphasis on collaborative operation, multilingualism, and ease of use. Distributed under the GNU GPL license, SPIP can be used for personal, association, institutional, or commercial sites.

For developers, system administrators, and professional users seeking a controllable and customizable open‑source CMS, SPIP remains an interesting solution. Its design is based on skeletons, loops, and a plugin system that allows the site’s functioning to be adapted to specific needs. In this approach, it can also be regarded as an open‑source solution suitable for organisations that wish to retain control over their web environment.

What problems does SPIP solve?

Choosing a CMS is not only about publishing articles. An organisation must also manage users, permissions, editorial structure, languages, visual customisation, and site evolution.

SPIP meets these needs with a collaborative‑publishing‑oriented approach. The official project highlights collective work and multilingualism as key platform characteristics . This orientation can satisfy the requirements of an open‑source service intended to support an organisation in managing its digital content.

SPIP can therefore be particularly relevant when a team wants to:

• publish content by multiple users;
• organise a site with a custom editorial structure;
• manage a multilingual site;
• customise the output through skeletons;
• extend functionality with plugins;
• retain control of the code and hosting;
• use software distributed under a free license.

A major benefit lies in the absence of a mandatory dependency on a proprietary platform. The software can be installed on the organisation’s own hosting, allowing it to control its infrastructure and data. This philosophy aligns with that of an open‑source project where the software and its infrastructure remain under organisational control.

Key Features and Capabilities

Editorial Management

SPIP is primarily built as a publishing system. Its admin interface allows management of content and the various participants of a site. 

The project philosophy favours separating content from presentation. Skeletons determine how content is displayed on the public site, enabling developers to heavily customise the rendering.

Customisation with Skeletons

Skeletons are one of SPIP’s distinctive technical elements. They define page structure and query site data via loops and tags.

This approach offers great freedom to developers but requires more technical knowledge than a fully drag‑and‑drop visual editor.

For an IT team, this architecture is valuable when the site needs a particular editorial structure or when the design must be fully controlled.

Plugins and extensions

The SPIP ecosystem allows adding functionality through plugins. The SVP plugin, for example, provides an admin interface for plugins and manages their dependencies.

he official catalogue contains extensions for various uses, including content, rendering, administration, forms, interactivity, and development.

Examples include plugins that generate PDF versions of content or add OAuth2 authentication features.

Multilingualism

Multilingual support is another historic strength of SPIP. The system handles content in multiple languages and can build skeletons that adapt to the current language.

Official documentation also describes how to create multilingual skeletons using language strings.

This feature benefits international organisations, associations, institutions, and companies with several language versions of their site.

Security and Maintenance

Security should be seen as a maintenance process, not a permanent property of a CMS.

SPIP regularly publishes security patches. Several updates of the 4.4 branch released in 2026 fixed various vulnerabilities, such as SQL injection, XSS flaws, remote code execution, and privilege escalation.

This means a professional SPIP installation must stay up‑to‑date, along with its plugins and server environment. For organisations that do not wish to handle this themselves, technical support adapted to their environment can be an important part of the operational setup.

Recommended practices

• Use a currently maintained version;
• Apply security updates promptly;
• Verify plugin compatibility before major upgrades;
• Secure the web server and database;
• Perform regular backups;
• Limit extensions to truly needed functionalities.

It would be inaccurate to present SPIP as inherently secure without conditions. As with any CMS on a server, its security level also depends on the version used, server configuration, installed plugins, and administration practices.

Performance and Technical Environment

SPIP 4.4 runs on PHP 7.4 to PHP 8.5. Official documentation lists required PHP extensions and compatibility with SQLite, MySQL, and MariaDB as specified by the project.

The officially stated minimum configuration for SPIP 4.4 includes roughly 150 MiB of disk space (excluding the database) and 128 MiB of RAM. These are minimum requirements, not recommendations for a high‑traffic professional site.

How to Install and Configure SPIP?

Step 1, Verify the Environment

Before installation, ensure the hosting meets SPIP 4.4 requirements: compatible PHP version and necessary extensions.

Step 2, Download SPIP

The official download page currently lists SPIP 4.4.23, released on 2 September 2026. Installation can be performed by downloading the archive and uploading the files to the host.

An alternative is using spip_loader.php, which launches the installation of the latest stable version directly from a browser.

Step 3, Complete the Installation

After placing the files on the server, the installation proceeds via the browser. Depending on the hosting environment, permission adjustments may be needed so that SPIP can create or modify certain data directories.

Step 4, Configure the Site

Once installation finishes, the administrator can set site parameters, create users, and install required plugins. 

For a professional environment, it is advisable to perform these steps on a test instance before applying them to the production site.

Use Cases for SPIP

SPIP can be used for a variety of web projects.

Institutional sites

Regularly publishing news, dossiers, and structured information.

Association sites

Collaborative publishing while retaining control over hosting and software..

Multilingual sites

Built‑in multilingual capabilities support organisations publishing in several languages.

Projects needing heavy customisation

Developers can leverage skeletons and plugins to create specific presentation models.

It is important not to attribute undocumented monetary gains to SPIP. No official source confirms, for example, that a given company reduced costs by 30 % using SPIP.

Comparison with Alternatives

SPIP is not the only open-source CMS available. In particular, it offers an open-source alternative for organisations seeking a free publishing solution, whilst retaining the ability to customise their environment. WordPress emphasises simplicity, flexibility and a vast ecosystem of plugins and themes. Drupal stands out in particular for its API-first architecture, its content structuring capabilities, its multilingual focus and its suitability for complex projects. Joomla also offers an extensible open-source approach, with a large ecosystem of extensions and templates.

The table offers a general comparison, not an absolute ranking. Drupal documents its API‑first architecture, multilingual functions, and scalability. WordPress highlights its thousands of plugins and theme system. Joomla also provides multilingual functions, permission levels, and a large extension ecosystem.

Advantages and disadvantages

Is SPIP Worth Using?

SPIP remains a serious option for organisations seeking an open‑source CMS with a strong editorial orientation, collaborative workflow, and extensive customisation possibilities.

Its primary interest is not to replace WordPress, Drupal, or Joomla systematically. The choice depends on the project, available skills, content structure, multilingual needs, and the desired level of customisation.

For developers or system administrators, SPIP is especially attractive when control over code, hosting, and editorial model matters more than having the largest possible ecosystem.

Conversely, an organisation aiming to minimise technical intervention should carefully evaluate the complexity of skeletons, plugins, and maintenance.

Conclusion

SPIP remains a relevant open‑source CMS for editorial, institutional, association, and multilingual sites. Its free licence, skeleton system, plugins, and collaborative publishing focus provide a flexible foundation for projects requiring strong control over the site. 

The main vigilance point is maintenance: numerous 2026 security updates demonstrate that a professional SPIP site must stay regularly updated.

In summary, SPIP should be considered when the priority lies in software freedom, customisation, multilingualism, technical control of the infrastructure, and support from an open‑source community. To decide between SPIP, WordPress, Drupal, and Joomla, it is preferable to start from the concrete requirements of the project rather than seeking a universally “best” CMS.
