Exponential Platform DXP Project Notice

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

This is an independent, 7x + community-driven continuation of the platform. The Exponential Platform DXP 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 DXP Project Status

Exponential Platform DXP has made it beyond its end of life in 2021 and survived. Current releases are primarily aimed at easing the requirements to support current versions of the PHP language like PHP 8.2, 8.3, 8.4, 8.5, 8.6 and beyond.

The platform is under active maintenance and targeted improvement. The 4.6.x (Platform v4) release line is the current stable version series of the Platform v4 Distribution. This is a standard single-kernel release running Exponential Platform v4 OSS on Symfony 5.4 LTS 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)
Exponential Platform v4 kernel patches for PHP 8.x runtime compatibility
Symfony 5.4 LTS alignment and dependency upgrades
Dependency upgrades across Composer and Yarn package ecosystems
Security patches and vulnerability triage
Documentation and developer experience improvements

Who is 7x

7x is the North American corporation driving the continued general use, support, development, hosting, and design of Exponential Platform DXP Enterprise Open Source Content Management System.

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 represents a serious company leading the open source community-based effort to improve Exponential Platform and its available community resources to help users continue to adopt and use the platform to deliver the very best in web applications, websites and headless applications in the cloud.

Previously before 2022, 7x was called Brookins Consulting — the outspoken leader in the active Exponential Platform Community and its portals for over 24 years.

7x offers:

Commercial support subscriptions for Exponential Platform DXP deployments
Hosting on the Exponential Platform cloud infrastructure (exponential.earth)
Custom development, migrations, upgrades, and training
Community stewardship via share.exponential.earth

What is Exponential Platform DXP?

Exponential Platform DXP runs a single, modern Symfony-native content kernel — Exponential Platform v4 OSS (Symfony 5.4 LTS). This is the standard release for new projects or projects that do not require the classic legacy kernel.

Recent Improvements to Exponential Platform DXP

Exponential Platform DXP 4.6.x (Platform v4) releases run Exponential Platform v4 OSS + Symfony 5.4 LTS — providing the modern eZ / Ibexa-lineage CMS experience with full PHP 8.x runtime support.

What Does Exponential Platform DXP Provide for End Users Building Websites?

Exponential Platform DXP is a professional PHP application framework with advanced CMS (content management system) functionality. As a CMS, its most notable feature is its fully customizable and extendable content model. It is also suitable as a platform for general PHP development, allowing you to develop professional Internet applications, fast.

Standard CMS functionality, like news publishing and forums, is built in and ready for you to use. Its stand-alone libraries can be used for cross-platform, secure, database independent PHP projects.

Exponential Platform DXP is database, platform and browser independent. Because it is browser based it can be used and updated from anywhere as long as you have access to the Internet.

Quick Start

# 1. Create project
composer create-project se7enxweb/exponential-platform-v4x-dxp-skeleton exponential_website
cd exponential_website

# 2. Configure environment
cp .env .env.local
# MySQL/MariaDB: edit DATABASE_HOST, DATABASE_NAME, DATABASE_USER, DATABASE_PASSWORD, APP_SECRET, APP_ENV
# SQLite (zero-config): set DATABASE_URL="sqlite:///%kernel.project_dir%/var/data_%kernel.environment%.db"
#                       and MESSENGER_TRANSPORT_DSN=sync://

# 3. Create database and import demo data
# MySQL/MariaDB first:
mysql -u root -p -e "CREATE DATABASE exponential CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_520_ci;"
# Then install:
php bin/console exponential:install --no-interaction

# 4. Set permissions
setfacl -R -m u:www-data:rwX -m g:www-data:rwX var public/var
setfacl -dR -m u:www-data:rwX -m g:www-data:rwX var public/var

# 5. Build frontend assets
source ~/.nvm/nvm.sh && nvm use 20 && corepack enable
yarn install && yarn build

# 6. Build Admin UI assets
php bin/console assets:install --symlink --relative public
yarn ibexa:build

# 7. Generate JWT keypair
php bin/console lexik:jwt:generate-keypair

# 8. Generate GraphQL schema
php bin/console ibexa:graphql:generate-schema

# 9. Clear all caches
php bin/console cache:clear

# 10. Start
symfony server:start
# → https://127.0.0.1:8000           (site frontend)
# → https://127.0.0.1:8000/adminui/  (Platform v4 Admin UI — admin / publish)
# → https://127.0.0.1:8000/api/ezp/v2/  (REST API v2)
# → https://127.0.0.1:8000/graphql   (GraphQL endpoint)
