SigNoz
Open-source observability platform providing unified collection and analysis of metrics, traces, logs, and LLM-specific monitoring data.
Pros
- Unified telemetry in single pane
- LLM-specific dashboards for token cost and latency monitoring
- self-hosted option eliminates vendor lock-in
Cons
- Setup complexity for self-hosting
- cloud platform (SigNoz Cloud) pricing less transparent than competitors
- smaller ecosystem of third-party integrations
Cost
The Community Edition is free and self-hosted; SigNoz Cloud Teams starts at $49/month including $49 of usage, after which logs and traces are $0.30/GB ingested with 15-day retention and metrics are $0.10 per million samples with one-month retention; a Startup Program cuts that to $19/month for the first 12 months for companies under three years old with fewer than 30 employees that have raised under $6 million; Enterprise is custom and starts at $4,000/month, with volume discounts on annual contracts.
Verdict
Best for AI/ML teams needing cost-effective observability with LLM-specific metrics and the flexibility to self-host.
