Our review
Pros
  • Memcheck detects memory errors and leaks in existing executables
  • Specialized tools cover CPU, cache, call graphs, heaps, and threads
  • Free, open-source, command-line workflow for native compiled programs
  • Continuous CPU and latency sampling in production
  • Flame graphs, heap summaries, and thread-state visualization
  • Integrates with Lambda, EC2, ECS, EKS, and Fargate
Cons
  • Instrumentation overhead can reduce suitability for general-purpose profiling
  • Primarily targets Unix-like environments, with Linux as its main development target
  • Local command-line workflows may require specialist developer knowledge
  • Supported languages are limited to JVM languages and Python 3.6 or later
  • Usage-based pricing requires monitoring sampling-hour consumption
  • The strongest platform coverage centers on AWS services
