This Is How We Made Postman Launch Twice as Fast

React Summit US

React Summit US 2025

We Made Postman Launch in Half the Time!Postman used to take 30 seconds to launch on some machines which felt like an eternity in the world of developer tools. Our engineers refused to accept that, so we went deep: profiling bottlenecks, re‑evaluating assumptions, and reshaping how the app loads and initializes.In this talk, you’ll learn the six concrete strategies we used to cut launch times in half, from code-splitting and deferring bundles to caching smarter and making Electron work for us, not against us. We’ll walk through how we identified hotspots, experimented with alternatives, and measured wins. You’ll come away with actionable ideas and a roadmap for making any large‑scale React or Electron app launch faster, making your users (and your team) a lot happier.
