About Perfbase

Perfbase is a purpose-built application performance monitoring platform for PHP. We believe PHP deserves profiling tools as good as what Go, Rust, and Python developers have.

Why we built this

PHP powers 77% of the web, yet performance monitoring for PHP is either outdated, overly complex, or built as afterthoughts on top of general-purpose APM platforms.

How it works

At the core is a native PHP extension written in Rust and C. It hooks into the Zend engine to instrument every function call with minimal overhead. Profiling data is serialized as MessagePack, compressed with Brotli, and sent to the Perfbase platform.
