Axomaly vs ObservabilityOS

Axomaly is a cloud service that learns patterns in SaaS product and business metrics and flags meaningful changes without fixed thresholds. It accepts timestamped time-series values, with optional metadata, for business, operational, and application metrics. Before creation, Smart Metric Creation prepares a detection configuration and baseline requirements for review. Values are submitted through a REST API, one timestamped value per POST request. Detection begins once the required history is available; the amount depends on metric cadence and detector configuration. Results include an anomaly decision, confidence, expected range, direction of change, and detector evidence, which can feed existing workflows alongside logs, traces, dashboards, and alerting. The alpha starts with one metric and includes guided onboarding and direct support. It is free during alpha with no credit card required. During that period, data and results are hosted in the EU, isolated by organisation, encrypted in transit using HTTPS/TLS, and kept for up to 12 months before rolling deletion.

ObservabilityOS collects structured logs and supports observability workflows across logs, metrics, and traces. It uses rolling statistical Z-score baselines to flag changes in error rates, latency, and CPU usage, then can use GPT-4 or Claude for incident analysis that describes what happened, why, and a suggested hotfix. Log collection options include a JavaScript/TypeScript SDK and a Docker sidecar for local logs or container output. The ingestion API supports native OTLP HTTP/JSON for existing collectors. Listed integrations include OpenTelemetry, GitHub, Slack, Discord, Microsoft Teams, Docker, Kubernetes, PostgreSQL, and Redis. Incident tools include threaded comments, runbooks, health dashboards, SLOs, and live SSE monitoring. The maker says telemetry is scrubbed before storage and sensitive client data is not sent to external LLMs. Plans include a free developer option, a free source-available self-hosted option, and Pro Cloud at $29/mo. The developer plan allows one service, 500MB of logs monthly, and seven-day retention; Pro Cloud lists 10 services, 10GB monthly, and 30-day retention.
