What SigNoz is
SigNoz is an open-source observability tool driven by OpenTelemetry. It brings application performance monitoring, distributed tracing, log management, metrics and dashboards, alerting, and LLM observability into one platform. A free community edition can be self-hosted on your own infrastructure, while the cloud version uses usage-based pricing. The product positions itself as an open-source alternative to tools such as Datadog or New Relic.
What you can do with it
- Monitor application performance and troubleshoot slow endpoints.
- Trace requests across services to find bottlenecks.
- Ingest, search, and analyze large volumes of logs.
- Build custom metrics and dashboards.
- Track LLM calls, performance, and usage for AI apps.
- Send actionable alerts to your preferred channels.
Who it is for
- Developers debugging application performance.
- Operations teams monitoring logs, metrics, and alerts.
- Enterprises consolidating observability into one stack.
What to watch out for
The cloud version is usage-based, so costs rise with data volume and retention. Self-hosting is free but shifts infrastructure, upgrade, and storage responsibility onto you. The feature breadth can be a lot for a small team, so start with traces or logs rather than enabling everything at once. Name and archive exported files consistently so you can find and reuse them, and keep a backup copy of key data. When quality matters, export a small draft first to confirm the result before producing the final file. Behavior may vary across browsers and devices, so test before production use and consult the help docs if errors appear. Features and interface details may change between versions, so review the latest notes on the page before you start. For team use, agree on naming and editing conventions in advance to avoid version conflicts or duplicated work.
