The simple, flexible and reliable website application engine
Exponential is the world's most flexible and reliable open-source CMS — a GPL-licensed continuation of the eZ Publish lineage, stewarded by 7x (se7enxweb) since 1998 and rebranded in August 2025. It provides an Office-like content editing interface that's easy to learn yet powerful enough for enterprise-scale deployments.
Backed by the Exponential Foundation (501(c)(3), approved May 2026), the platform offers multi-database support (MySQL, SQLite, and experimental MongoDB), deep Symfony integration, full legacy bridge compatibility with eZ Publish 4.x, and a growing forge of 3,900+ open-source extensions and projects. No vendor lock-in. No proprietary pivot. Free forever.
