Summary
ObserveOne API Monitoring runs saved HTTP requests on demand or on a schedule and checks them against assertions for status codes, response times, JSON path values, headers, and response-body text. Checks can use scheduled retries, configurable timeouts, and selected execution regions. Authentication options include Bearer, Basic, API-key, and OAuth2 client-credentials methods through vault references. Each check has a write-only secrets vault; stored monitoring secrets are encrypted with authenticated AES-256-GCM, while results remain readable. Alert destinations include email, Slack, Discord, Microsoft Teams, Telegram, SMS, and webhooks. The product offers a web dashboard, CLI, MCP server, and REST API. GitHub integration can trigger runs on pushes and post statuses and comments on pull requests; the Netlify extension runs selected suites after successful deployments. An open-source engine can be self-hosted with Docker Compose. The free plan is free and has a two-hour minimum URL-monitor interval. Starter costs $6.00 USD per month, billed annually. Cloud TCP, UDP, and database checks need publicly reachable targets.
Who it is for
ObserveOne suits engineering teams that need scheduled API checks, response assertions, and alerting. It may also fit teams wanting GitHub or Netlify automation or a self-hosted worker engine.
