The short version

  • Only Langwatch has a free tier, so it costs nothing to try first.
  • Each has a real cost: AppDynamics appdynamics.com/pricing returns a 301 redirect to Splunk's observability pricing page; the product is now sold as Splunk AppDynamics; Langwatch free plan limited to 50k events per month, restricting larger deployments
  • They diverge on capability: AppDynamics covers Application performance monitoring, Langwatch covers Agent simulation testing.
