Open Source Performance Monitoring (APM) Software
Performance Monitoring (APM) software tracks the health and speed of web applications and servers. These tools correlate logs, metrics, and distributed traces to identify the root cause of software errors and latency. This type of software is for developers and system administrators who need to debug microservices or optimize LLM prompts. Self-hosting these apps ensures that sensitive session replays and server logs remain on private infrastructure. This approach allows teams to manage high volumes of observability data without paying based on the amount of ingested telemetry.
This page lists 13 open source tools in the Performance Monitoring (APM) category. The most popular are Sentry, SigNoz and OpenObserve. Most use the AGPL-3.0 or Apache-2.0 license, and 11 offer an official Docker image.
Sentry
An error tracking and performance monitoring platform that helps developers detect and resolve software issues through debugging.
SigNoz
Collects and correlates logs, metrics, and traces in a single interface for microservices observability and troubleshooting.
OpenObserve
Manage logs, metrics, and traces within a single observability platform using SQL and PromQL queries.
OpenReplay
A self-hosted session replay and product analytics suite for troubleshooting web application issues and monitoring performance.
Arize Phoenix
Trace, evaluate, and optimize LLM applications with an observability platform featuring prompt management and dataset versioning.
HyperDX
An observability platform that unifies logs, traces, metrics, and session replays on top of ClickHouse clusters.
Highlight
