Summary
ObserveOne API Monitoring runs saved HTTP requests on demand or on a schedule and checks their results against assertions. A check can validate status codes, response times, JSON path values, headers and text in a response body. Checks can retry on a schedule, use configurable timeouts and run from selected regions. Authentication options include Bearer, Basic, API-key and OAuth2 client-credentials methods using vault references. The per-check secrets vault is write-only, and stored monitoring secrets are encrypted with authenticated AES-256-GCM; results remain readable. Alerts can go to email, Slack, Discord, Microsoft Teams, Telegram, SMS or webhooks. Users can manage the service through its web dashboard, CLI, MCP server or REST API. GitHub can trigger runs on pushes and post pull-request statuses and comments; the Netlify extension runs selected suites after successful deploys. An open-source engine supports self-hosting with Docker Compose. A free plan is available; paid plans start at $6/mo (annual).
