Deoptigate is a CLI tool that investigates V8/Node.js function deoptimizations by processing v8 logs and presenting them in a visual viewer. It helps developers track down and fix performance bottlenecks caused by deoptimized functions.

Use cases

  • investigate why my node.js function got deoptimized
  • analyze v8 log for deoptimizations
  • find performance bottlenecks in node app
  • visualize v8 optimization and deoptimization events
  • debug slow javascript functions in node

When to choose

  • you're profiling node.js apps and need to see deoptimizations inline with source code
  • you have existing *-v8.log files you want to analyze visually

When to avoid

  • you need general CPU profiling rather than deoptimization analysis
  • you're targeting browsers or non-V8 runtimes
