New here? Everything on this page is designed for you — but the fastest next step depends on what you need to accomplish. Pick your role and see the options that are most relevant.

You write PHP, work with Symfony, or build for eZ Publish / Exponential Platform. You want to ship faster, fix less, and build on a stack that stays alive.

What you can do:

You manage content, publish articles, run editorial workflows, and keep websites current. You want an administration interface that works the way you think.

What you can do:

You build themes, front-ends, page layouts, and visual experiences on top of Exponential Platform. You want a design system that stays current and a layout engine that gives you real control.

What you can do:

You run a website or digital product built on eZ Publish or Exponential Platform. You need it secure, fast, and well-supported — and you need results, not roadmaps.

The bottom line: This is a 24-year-old platform maintained by a single North American company as free, open-source software. Every dollar of sponsorship or service revenue directly extends the platform's life and the quality of the tooling your site depends on.

What you can do:

The Exponential Platform ecosystem is maintained by a small team. Every release, every security fix, and every PHP compatibility update is funded by the community. We have two sponsorship streams — one for the company, one for the open-source project. Both matter. Both need your support.

The Exponential Foundation funds the open-source project: the core libraries, the documentation, the community tooling, and the long-term survival of the platform as free software. Your sponsorship funds:

• Core library maintenance — exponential, exponential-platform, exponential-platform-legacy
• API documentation at api.exponential.earth
• Core documentation at doc.core.exponential.earth
• GraphQL, REST, and Solr — modern integration layers for headless and API-first builds
• Community infrastructure — Slack, mirrors, wikis, and developer resources
• zetacomponents security hardening — 14 upstream security PRs submitted in April 2026 alone

Sponsor now → github.com/sponsors/exponentialcms

Foundation sponsors are listed in the project's CONTRIBUTORS file and on exponential.earth. Foundation sponsors at higher tiers receive roadmap input and co-marketing opportunities.

💡 Can't sponsor monthly? A one-time contribution at either link goes directly toward the work described above. Every dollar extends the runway. If your business runs on this platform, sponsorship is maintenance budget, not charity.

The platform originally known as eZ Publish reached end-of-life in 2021. We kept going. We maintain Exponential Platform — 100% source-compatible with the original eZ Publish stack (trademark usage removed) — through PHP 8.2, 8.3, 8.4, 8.5 and actively preparing for PHP 9.

Active work in progress:

• 🔒 Security hardening across the full Zeta Components library — 14 security PRs submitted upstream to zetacomponents covering session fixation, SSRF, SQL injection, path traversal, predictable lock tokens, shell injection, and RCE via eval(). All changes verified against live source before any PR was opened.
• 🐘 PHP 8.5+ compatibility — active fork of Symfony maintained at se7enxweb/symfony for General Public Use (GPL)
• 🔁 Database translator — sevenx_exponential_platform_v5_database_translator intercepts every SQL query before it hits the wire and translates MySQL syntax to PostgreSQL in real-time, giving users a genuine choice of database
• 📦 Distribution packages — Exponential Platform DXP and Exponential Platform Nexus deliver the full stack (modern Platform + Legacy Bridge) as ready-to-install Composer packages
• 📚 Free training book mirror — three original developer training books (700+ pages combined) mirrored at mirror.exponential.se7enx.com so they are never lost

7x has been in business supporting this platform and its community for 24+ years. Previously known as Brookins Consulting, we took over leadership of the open-source project in 2023. Everything we do is GPL-licensed and freely available.

The bridge between the modern Symfony/DXP stack and Exponential Platform Legacy. Without this, legacy extensions and templates cannot co-exist with the new kernel. Co-maintained with the community. If you run a mixed stack, this is not optional.

The complete integrated distribution: Platform (Ibexa v2/3/4/5 OSS) + Exponential Legacy — in one Composer meta-package. The fastest path from zero to a running full-stack installation.

Intercepts every SQL query before execution and transparently rewrites MySQL syntax to PostgreSQL. Run a MySQL-written CMS on Postgres with no query changes. Underserved and genuinely unique.

Forms, data collection, submissions — the feature that's always missing from CMS platforms. Build contact forms, surveys, and data capture workflows directly inside the content model.

A field type that builds dynamic content listings by querying the repository — no custom PHP required. Define a query in the content model and get a rendered list. Massively underused.

Content and schema migrations as version-controlled YAML files. Run migrate on deploy the same way you run database migrations. Essential for any professional deployment pipeline.

Copy entire content subtrees (including NG Layouts page configuration and section assignments) in one operation. Solves a genuinely hard problem for multi-site and content staging workflows.

An alternative administration UI that implements a cleaner, more modern editorial experience on top of the Platform kernel. If the default admin UI doesn't fit your editorial workflow, this does.

Adds a UI control to the Online Editor (AlloyEditor) for setting element width directly — a small but constantly-requested editorial capability that the base editor omits.

The Twig template engine, maintained for use with Exponential Platform. Kept current with PHP compatibility fixes.

Full metadata management for Exponential / eZ Platform content — titles, descriptions, Open Graph, Twitter Cards. Based on xrowmetadata. The most complete SEO metadata solution available for this stack.

SEO bundle for Exponential / eZ Platform. Handles sitemap generation, robots.txt, canonical URLs, and SEO field configuration per content type. Based on Novactive's work, maintained by 7x.

A video datatype with automatic transcoding into multiple formats and bitrates, plus a built-in video player. Handles upload → encode → serve without leaving the CMS.

SVG editor and datatype for Exponential Platform Legacy. Edit SVG content inline in the CMS.

A Legacy extension that provides a way to include Twig templates inside eZ Publish Legacy template code. Bridges the template worlds so you don't have to maintain two separate UI stacks.

Extra search capabilities for Exponential / eZ Platform — additional criteria, sort clauses, and field-level search features not available in the standard search layer.

System information and diagnostics bundle. Shows PHP version, extension status, database connectivity, and configuration health at a glance. Essential for auditing deployments.

Symfony Flex recipes for Exponential Platform DXP. Automate configuration file setup and bundle registration when installing packages. Pairs with exponential-platform-dxp.

A standard editorial publishing workflow for Exponential Platform Legacy — draft, review, approve, publish. The most complete open-source workflow solution for this stack.

Questionnaires, polls, and quizzes built directly into the content model. Collect structured responses from visitors without a third-party tool.

A complete, production-grade media website built on Exponential Platform + Netgen Layouts. This is the reference implementation that shows best practices for content modelling, theming, and layout management. Start here if you're building a content-heavy site.

The Legacy variant of the media site — Ibexa v4 OSS + Exponential Legacy together. A working reference for mixed-stack deployments.

Three original developer training books — 700+ pages — free to download:

These books describe the architecture that Exponential Platform is built on. Everything in them applies directly to development work on the platform today.
