SigNoz is an open-source, OpenTelemetry-native observability platform for your team and their AI agents. Get logs, metrics, and traces in one tool with features like APM, distributed tracing, log management, infra monitoring, etc. Combined with SigNoz MCP and a native AI teammate (in SigNoz Cloud) it helps you build more resilient apps.
Metrics, logs and traces in one app, built on OpenTelemetry and ClickHouse.
The fastest path to AI-powered full stack observability, even for lean teams.
Per-second infrastructure metrics and alerts; the agent is GPL, its dashboard UI is closed source.
The open and composable observability and data visualization platform. Visualize metrics, logs, and traces from multiple sources like Prometheus, Loki, Elasticsearch, InfluxDB, Postgres and many more.
Dashboards and alerting over metrics, logs and traces stored in your own backends.
The Prometheus monitoring system and time series database.
Metrics and alerting you run yourself; logs and traces need other tools.
Like Prometheus, but for logs.
Covers log management, usually paired with Grafana for dashboards and alerts.
Open source observability platform for logs, metrics, traces, RUM (web, android, ios), Session replay, pipelines, SLO and LLM observability. A sophisticated, simple and highly performant alternative to Datadog, Splunk, and Elasticsearch with 140x lower storage costs and single binary deployment.
Logs, metrics, traces and dashboards in one service you run yourself.
VictoriaMetrics: fast, cost-effective monitoring solution and time series database
Metrics storage and alerting you run yourself; logs and traces need other tools.
Highly available Prometheus setup with long term storage capabilities. A CNCF Incubating project.
Long-term metrics storage only.
Continuous Profiling Platform. Debug performance issues down to a single line of code
Continuous profiling only, the part Datadog sells as its Continuous Profiler.
Resolve production issues, fast. An open source observability platform unifying session replays, logs, metrics, traces and errors powered by ClickHouse and OpenTelemetry.
Search and chart logs, metrics, traces and session replays stored in ClickHouse, with alerts.
Coroot is an open-source observability and APM tool with AI-powered Root Cause Analysis. It combines metrics, logs, traces, continuous profiling, and SLO-based alerting with predefined dashboards and inspections.
eBPF-based service maps, metrics, logs, traces and profiles, with no code changes needed.
Real-time monitoring of IT components and services, such as networks, servers, VMs, applications and the cloud.
Infrastructure and network monitoring with agents, templates and alerting; no APM.
Grafana Mimir provides horizontally scalable, highly available, multi-tenant, long-term storage for Prometheus.
Metrics storage only, usually paired with Grafana.
Continuous profiling for analysis of CPU and memory usage, down to the line number and throughout time. Saving infrastructure cost, improving performance, and increasing reliability.
Continuous profiling only, with an eBPF agent that needs no code changes.
Open source APM: OpenTelemetry traces, metrics, and logs
APM, logs and metrics from OpenTelemetry data, without Datadog's agents and integrations.
