What ObservabilityOS is
ObservabilityOS is an observability platform that ingests structured logs, scrubs sensitive data, detects anomalies, and creates AI-assisted incident post-mortems. Its rolling statistical Z-score baselines look for unusual error rates, latency, and CPU usage. Incident analysis uses GPT-4 or Claude to describe what happened and why, and suggest a hotfix. Logs can come through a JavaScript/TypeScript SDK or a Docker sidecar that collects local logs and container output. The platform also supports native OTLP HTTP/JSON ingestion and lists integrations including OpenTelemetry, GitHub, Slack, Discord, Microsoft Teams, Docker, Kubernetes, PostgreSQL, and Redis. Incident tools include threaded comments, runbooks, service health dashboards, SLOs, and live SSE monitoring. The site says telemetry is scrubbed before database storage and sensitive client data is not sent to external LLMs. A free source-available self-hosted plan uses Docker/Compose. The Free Developer plan includes one service, 500MB of logs per month, and seven-day retention. Pro Cloud is $29/mo, with 10 services, 10GB monthly logs, and 30-day retention.
