  • Service mapping
  • Business workflows
  • Smart dynamic alerting
  • Trace ingestion and retention

6. Datadog

datadog (1) If you require an application performance monitoring platform that is able to provide end to end distributed tracing then Datadog may be the right tool to fulfil this particular use case.

Datadog’s APM platform is said to have twice as many features as New Relic so may provide users with more value if they need extensive configuration and additional monitoring features.

In recent years users have noted that the feature gap between Datadog and competitors such as Instana, Dynatrace & Appdynamics is quickly closing so you may wish to trial a few APM platforms side by side to see which service performs the best for your particular use case.

The majority of New Relic’s closest competitors are included in this list already but a few more that haven’t previously been mentioned include Microsoft Azure Application Insights, Nexthink and Aternity APM.

Key Features:

  • Unlimited alerts
  • Anomaly detection
  • Unlimited incident events

9. Loupe

loupe (1) If you require an APM solution specifically for Java & .NET monitoring, then look no further than Loupe. The Loupe platform was created back in 2009 by Gibraltar Software Inc. In addition to APM, Loupe also offers a centralised logging platform that supports both real-time remote log viewing and active directory integration.

Key Features:

  • Unlimited users
  • Unlimited errors
  • Unlimited applications

10. Appoptics

appoptics (1) Solarwinds backed solution Appoptics provides users with the ability to monitor not only applications but also infrastructure and server monitoring in one centralised platform. Appoptics has been the APM tool of choice by companies such as Traxco and TechValidate according to their recent case studies.

Key Features:

  • Distributed tracing
  • Exception tracking
  • Root cause summary

11. Scouter

scouter (1) Scouter’s application performance management tool provides an open-source alternative to proprietary services such as Appdynamics and New Relic. Open source tools can offer a more affordable alternative to using closed source platforms and these also benefit the user additionally by often offering more community support as well as simplified license management.

12. AppDynamics

appdynamics (1) AppDynamics offers a performance monitoring tool that is well suited for alleviating silos in visibility by offering full-stack observability. It is worth bearing in mind that Appdymanics has previously received criticism based on their support or lack thereof, as well as the high cost associated with the deployment and configuration of their tool. This is yet another tool that is highly rated for its extensive amount of third-party integrations.

13. StageMonitor

stagemonitor (1) Stagemonitor’s open-source APM has been especially built with the monitoring of Java applications as its primary objective. As is the case with a number of tools in this roundup, Stagemonitor is often used in association with other open-source tools as part of a wider observability stack. This means that users of Stagemonitor may only use it for its APM capabilities and may decide to keep log aggregation confined to ELK (Elasticsearch, Logstash & Kibana).

Some users who wish to formulate a suitable alternative to New Relic may also add InfluxDB to this mix of different technologies. This setup will have overheads and costs associated with its upkeep due to the employees who are required to host, configure and maintain this stack.

14. ManageEngine

ManageEngine’s applications manager gives users the opportunity to improve their application performance and troubleshoot with ease. Unfortunately, the platform has faced criticism based on its dated user interface and its lack of ability to offer seamless platform upgrades.

17. Apache Skywalking

skywalking (1) Apache Skywalking is an open-source application monitoring tool that sports framework support and core features that may satisfy many users' open-source APM requirements.

While the platform UI still leaves much to be desired, this is going to be more affordable as a solution than many proprietary platforms (such as Datadog or Splunk). It is noted by some users that Skywalking may be used in isolation or as part of a wider technology stack (with some users opting to manage logging in a separate ELK Stack).

Key Features:

  • Support for Java, .Net Core, PHP, NodeJS and Golang agents
  • Customizable dashboard
  • Envoy service mesh support
  • Trace and profile explorer
  • Topology map

The platform's automation features extend to the discovery, mapping and configuration of cloud-native applications.

Key Features:

  • Service dependency map
  • Distributed tracing
  • Custom metrics
  • Analyzed traces
  • No sampling

20. SigNoz

signoz (1) SigNoz is an open-source application performance monitoring solution that was developed as an alternative to Datadog. The platform was initially built using Prometheus and Grafana but creator Pranay Prateek didn't believe that this was a comprehensive enough solution which inspired him to build his own end to end APM solution that was fully open source.

Unfortunately, when last checked SigNoz did not have real user monitoring on their planned features roadmap, this isn't to say that this won't be added in the future but users may have to express more interest before this feature is planned.

Due to its widespread adoption SigNoz benefits from offering a wealth of user stories from industry-leading organisations including its use as an APM solution by Netflix, Groupon and Uber Eats.

Key Features:

  • Custom aggregates on filtered traces
  • Slowest application endpoints
  • Application overview metrics
