Runscope vs Tallwatch

Runscope provides API testing and monitoring for development and QA teams. It helps teams check uptime, correctness, and performance from the API consumer's point of view, automate tests in CI/CD pipelines, and monitor live APIs. A test runs one or more HTTP requests in sequence, with assertions and variables for checking responses and passing data between steps. Assertions can cover response time, JSON or XML content, headers, status codes, and response bodies. Tests can run in the cloud or behind a firewall against public or private APIs. Teams can chain requests, use dynamic data, reuse checks across local, staging, and production environments, and import API definitions from Swagger or OpenAPI; the Small plan also lists Postman import. Notifications for completed or failed runs include email, webhook, PagerDuty, and Slack. An on-premises agent supports private API monitoring on macOS, Linux, and Windows. The Free Starter plan includes 1,000 API Monitoring and API Functional Testing runs per month. Small costs $79 a month; the homepage says API Monitoring (Runscope) is now available through BlazeMeter.

Tallwatch monitors websites and APIs from multiple regions and opens an incident when at least two regions report the same failure in a check round. Check types include HTTP, keyword, ping, TCP, DNS, SSL, and heartbeat, with probes in Virginia, Frankfurt, Singapore, Sydney, São Paulo, and Oregon. Alerts can be routed to email, Slack, Microsoft Teams, Telegram, Discord, PagerDuty, and signed webhooks. On-call rotations and escalation policies direct incidents to responders until acknowledgment. Public or private status pages can use a custom domain and include incident history and email or RSS subscribers. Developers can manage monitors and triage incidents using a REST API, CLI, or hosted MCP endpoint. The CLI runs on macOS, Linux, and Windows and can import monitors from UptimeRobot. The free plan includes 10 monitors and 60-second checks from three regions. Pro costs $11.99 a month billed annually, or $14.99 a month billed monthly; Business is $19.99 a month billed annually, or $24.99 a month billed monthly. Tallwatch says it does not publish a formal customer uptime SLA with automatic credits.
