Our review
Pros
  • Free plan includes 50 GB monthly ingestion and 14-day retention
  • Supports CPU, memory, and thread profiling across many languages
  • Grafana, eBPF, APIs, multi-tenancy, and horizontal scaling
  • 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
Cons
  • Pro adds usage-based charges for processed, written, and retained data
  • Free plan support is limited to the community
  • Advanced deployments may require instrumentation or platform configuration
  • 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
