Laravel Octane in Production: What Docs Don't Tell You
An in-depth look at running Laravel Octane in production, comparing FrankenPHP, Swoole, and RoadRunner engines while managing memory leaks.

- Laravel Octane delivers massive performance boosts for Laravel applications but introduces state management challenges.
- Engine choices include FrankenPHP, RoadRunner, and Swoole, each with distinct operational trade-offs.
- Developers must audit singletons and cap worker lifecycles to prevent memory leaks in production.
Laravel Octane promises speeds that make traditional PHP-FPM look sluggish, handling thousands of requests per second with single-digit millisecond response times. However, the gap between marketing claims and production reality is often filled with memory leaks, stateful traps, and unexpected 3 AM server restarts.

Octane offers three engines: FrankenPHP, Swoole, and RoadRunner. While official documentation treats them as interchangeable options, they differ significantly. FrankenPHP is a Caddy-based server that installs smoothly for most teams. RoadRunner, written in Go, offers robust process management. Swoole is the fastest on paper but the hardest to debug when issues arise.
Moving from PHP-FPM to Octane is a fundamental architectural shift. Instead of destroying application state at the end of every request, Octane keeps the application booted in memory across requests, requiring a disciplined approach to variable scoping and dependency injection.
Under PHP-FPM, every request isolates execution, destroying singletons and static properties automatically. Octane preserves application state in memory across requests. The fix requires auditing your singletons, favoring bind() over singleton() for request-scoped bindings, and utilizing Octane lifecycle hooks like Octane::tick() and flush callbacks.

Even clean codebases experience minor memory leakage over long-lived worker lifecycles. To mitigate this, configure worker recycling in config/octane.php by setting max_requests to 500. Monitor memory consumption steadily to ensure workers recycle properly during deployments using octane:reload.
Additional production considerations include sizing workers to match actual CPU cores, maintaining optimized OPcache settings, and warming up caches prior to routing live traffic to prevent initial latency spikes on fresh workers.
