Remember when profiling Node.js meant wrestling with perf, sed scripts, and mysterious V8 internals? Traditional flame graph generation has been like performing surgery with a rusty spoon, requiring kernel-level tools and arcane command-line incantations. The barrier to entry is sky high. The time to insight is glacial.
We've completely reimagined this at Platformatic with @platformatic/flame - a zero-config profiling tool that works instantly. Just run flame run server.js and get production-grade flame graphs. Combined with our WebGL-accelerated React component library (react-pprof), we handle massive datasets with buttery-smooth 60fps interactions. This isn't just another tool - it's about democratizing performance analysis.
When your Auth Service hits 96% Event Loop Utilization, you need answers NOW. I'll show you our ecosystem-compatible architecture, how we profile microservices in-memory with Watt, and real production cases where this saved millions in infrastructure costs. Performance is everybody's responsibility, but the tools have been nobody's friend until now.

We love building new features, but what about the other side of frontend development? Keeping your codebase healthy, managing tech debt, and optimizing performance are just as important. How do you start deleting code, tracking the right metrics, and collaborating with other teams to keep things fast and clean?In this talk, I’ll share practical tips and stories from working on a long-standing website layered with years of web history and various technologies. If you're ready to dive into the essential work of maintaining a frontend, this one’s for you!
