Why FreeUnit

PHP 8.4 + 8.5

First-class support for modern PHP runtimes. The primary motivation for this fork.

Security Backports

Active security maintenance. No more unaddressed CVEs in archived repositories.

Stable Releases

Predictable LTS release cycle. Production deployments need guarantees.

Community Governed

No corporate control. Decisions made by active contributors.

Installation

      # Build from source

      git clone https://github.com/freeunitorg/freeunit

      cd freeunit

      ./configure --openssl --otel

      make

      sudo make unitd-install

Official packages and Docker images are coming soon.
PHP 8.5 support requires FreeUnit — not available in the archived upstream.
