The Manychat Story: Scaling Facebook webhooks from zero to 25,000 requests per second with PHP

Every great platform starts with a small idea and grows into something extraordinary. In this talk, I'll share the inspiring journey of Manychat and how we scaled Facebook webhook handling from very humble numbers to a system processing 25,000 requests per second — all powered by PHP, all while operating on minimal resources. Whether you're working on a startup or managing a high-traffic system, this session will inspire you to see the full potential of PHP in scaling your own projects.
