Checkly

Active reliability platform combining uptime monitoring, API testing, and incident response

Overview

What Checkly does

Checkly is an active reliability layer for developers and AI agents that combines testing, monitoring, alerting, and incident communication into one platform. The platform operates on monitoring-as-code principles, enabling teams to define checks in TypeScript/JavaScript and deploy them to 20+ global monitoring locations. Checkly supports multiple monitoring types including uptime monitoring (for URLs, TCP, DNS, databases), synthetic browser testing using Playwright, heartbeat monitoring for cron jobs and background tasks, and API monitoring with assertions. The platform integrates with incident management tools like PagerDuty, OpsGenie, and Slack for alerting, provides branded status pages with automated updates, and includes Rocky AI for automated root cause analysis using OpenTelemetry tracing data. Notable users include Vercel, CrowdStrike, Airbus, Mistral, 1Password, and Fastly.

What people use it for

Monitor API endpoints with custom assertions
Test user journeys with browser automation
Detect performance degradation across regions
Verify DNS and TCP connectivity
Ensure cron jobs and background tasks complete

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Checkly.

Free tier has limited check allocations per month
Overage charges can add up with high-volume workloads
Status pages require separate paid tier
Root cause analysis is separate billing component

Softwr does not host reviews and shows no star rating for Checkly, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
