pH7Builder (formerly pH7CMS) is a free, open-source PHP 8 dating CMS available on GitHub and actively maintained. It ships with over 40 modules covering profiles, matchmaking, messaging, video chat, a blog, and affiliate integration, with a low server footprint by design. Being fully open source with no license fee makes it accessible for operators who want to self-host without upfront cost and have the technical team to customize the stack. The code is clean and structured around a custom MVC framework.

Being community-driven, paid commercial support is limited - operators without in-house PHP skills should budget for a developer, not lean on vendor hand-holding.
