Checkly

Checkly is a reliability platform for developers that combines testing, synthetic monitoring, alerting, status pages and tracing. The founding year is not stated on the fetched pages; its terms list Checkly Inc. with a Boston, Massachusetts address.

Teams define checks as code (JavaScript or TypeScript, Terraform, Pulumi) and deploy them with a CLI to more than 20 global locations. Monitors cover uptime, API, Playwright browser, heartbeat, DNS, SSL and gRPC checks, with AI root-cause analysis and OpenTelemetry traces. Customers shown include Vercel, Airbus, CrowdStrike and 1Password.

• Synthetic monitoring: Playwright browser checks, API, heartbeat, DNS, SSL and gRPC monitors.
• Monitoring as code: CLI, TypeScript constructs, Terraform and Pulumi support.
• Alerting: routing to Slack, PagerDuty, OpsGenie, Teams and Telegram.
• Status pages: component-based pages with RSS, Atom and Slack feeds.
• AI root-cause analysis: Rocky AI and OpenTelemetry traces for failed checks.
• MCP server: AI agents can create and manage checks and monitors.

A Vietnamese e-commerce site can run Playwright checkout checks every few minutes and alert on failures. A banking app team can monitor API endpoints and SSL certificates from multiple regions. A SaaS company can publish a status page for customers.

Monitoring as code keeps checks in version control and CI pipelines. Playwright-based checks test real user flows from 20+ locations. Alerts route to Slack, PagerDuty, Teams and others, and status pages inform customers during incidents. SOC 2 compliance and AWS Marketplace availability ease procurement.

Engineering teams are moving end-to-end tests into production monitoring and treating monitoring configuration as code. Playwright has become a common browser testing standard. Vietnamese e-commerce, banking app and SaaS teams with strict uptime expectations can use synthetic checks from global locations to catch regional failures.

Checkly Inc., Boston, Massachusetts per its terms; founding year not stated. SOC 2 badge, Gartner Cool Vendor recognition (undated) and AWS Marketplace listing. Changelog shows monthly releases from May to September 2026, including the MCP server launch in June 2026.
