Exponential Platform Project Notice

"Please Note: This project is not associated with the original eZ Publish software or its original developer, eZ Systems or Ibexa."

This is an independent, 7x + community-driven continuation of the platform. The Exponential Platform codebase is stewarded and evolved by 7x (se7enx.com) and the open-source community of developers and integrators who have relied on it for decades.

Exponential Platform Project Status

Exponential Platform 3.2.9 is the current stable release on the 3.2 branch. It runs the Exponential Platform kernel on Symfony 5.1/5.4 LTS (full-stack, single kernel — no LegacyBridge) with full PHP 8.x support. Ongoing work focuses on:

Continued PHP 8.x compatibility (8.2, 8.3, 8.4, 8.5 tested and supported)
Dependency upgrades across Composer and Yarn package ecosystems
Security patches and vulnerability triage
Documentation and developer experience improvements

Who is 7x

7x has been in business supporting Exponential Platform website customers and projects for over 24 years. 7x took over leadership of the project and its development, support, adoption and community growth in 2023.

7x offers:

Commercial support subscriptions for Exponential Platform deployments

Custom development, migrations, upgrades, and training
Community stewardship via share.exponential.earth

What is Exponential Platform?

Exponential Platform is a fully open source professional CMS (Content Management System) developed by 7x and the Exponential Platform community.

The 3.2.x release runs on the Symfony 5 framework (Full Stack) — a single-kernel architecture using the Exponential Platform content repository, REST API v2, GraphQL, JWT authentication, and Webpack Encore asset pipeline.

Very extensible — Extend the application and content model in many ways.
Future and backwards compatible — Strong backward compatibility policy on data as well as code.
Multi-channel by design — Strong focus on separation between ^semantic content and design.
Scalable — Easily scale across multiple servers out of the box.
Future proof — Architecture designed to allow even more content scalability and performance.
Stable — Built on experience in building CMS gathered since early 2000.
Integration friendly — Numerous events and signals to hook into for advanced needs.

Exponential Platform is fully open source and is the foundation for the commercial Exponential Digital Experience Platform software, which adds advanced features for editorial teams, entirely built on top of Exponential Platform APIs.
