Small Project is a website development organization.
This site regroup it's open source developments.

OSmall Project open source developments are focused on improving the PHP ecosystem. I strive to develop generic libraries that can be integrated into any framework, but I primarily focus on integrating them into Symfony bundles, as it is the framework I use most often. Feel free to develop plugins for your favorite framework and share them with the community.

OMany of the small project libraries are dependent on Swoole and OpenSwoole. Swoole provides access to coroutines, along with WebSockets and an embedded HTTP server. PHP with the Swoole HTTP server benchmarks similarly to Go benchmarks.
