What it does
SigNoz is an open-source alternative to DataDog. We help developers find issues in the software they run on cloud and solve them quickly. Run SigNoz in your infrastructure and get your application monitoring setup at 10x lower cost
SigNoz Cloud is a one-stop observability tool built on top of OpenTelemetry. Get APM, logs, traces, metrics, exceptions, AI observability & alerts in a single tool.
SigNoz Cloud brings your traces, metrics, and logs into one OpenTelemetry-native platform. Simple usage-based pricing, and the freedom to run on your infrastructure with Self-Hosted SigNoz. See how teams use SigNoz to resolve issues faster and build with confidence. Move from symptoms to evidence across APM, logs, traces, infra, LLM telemetry, alerts, and dashboards. Use the SigNoz MCP server to bring telemetry into coding agents, or use Noz, your AI teammate inside SigNoz Cloud, to investigate incidents, tune alerts, and build dashboards with the same production context your team sees. I can help you understand and be the all-seeing eye over your entire infrastructure. What do you need?…from signoz.io
