How AI is used

Checkly is an application monitoring platform designed for developers and engineering teams to monitor service availability. It combines uptime checks with synthetic monitoring, which supports simulating user interactions to identify functional errors before they impact users.

The platform supports a 'Monitoring as Code' workflow via its own CLI, Terraform, and Pulumi, allowing monitors and alerts to be versioned and managed as code. It also includes observability tools such as distributed tracing and AI-supported root cause analysis through Rocky AI.

Buyers should confirm if their team has the technical capacity to manage monitoring via code and if they require specific global check locations, as the platform supports deployment to over 20 locations.

Key Features

  • Synthetic Monitoring

    Uses Playwright to simulate user flows, such as logins and checkout processes, to identify functional errors.

  • Uptime Monitoring

    Tracks the availability of URLs, TCP ports, DNS, and database backups from multiple global locations.

  • API Checks

    Supports HTTP requests with assertions for status codes and JSON properties, including multi-step flow scripting.

  • Monitoring as Code

    Supports the creation and versioning of monitors using Checkly CLI, Terraform, or Pulumi.

  • Rocky AI Analysis

    Provides automated root cause analysis of check runs to help identify why a failure occurred.

  • Status Pages

    Provides branded pages to communicate application availability and status updates to customers.

Use Cases

  • API Availability Tracking

    Monitoring specific API routes and endpoints to ensure they return the correct status codes and response times.

  • Critical User Path Testing

    Using browser checks to verify that essential flows, such as a checkout process, are functioning correctly in production.

  • Infrastructure Health Checks

    Using TCP checks to monitor the availability of services like SSH or SMTP.

  • ETL Pipeline Monitoring

    Setting up heartbeat checks to ensure nightly data pipelines complete as expected.
