### World-class engineering and SRE teams depend on Checkly to deliver reliable digital experiences

### Clear signal over noise

Focus on what matters to your users, not drowning in telemetry. Outside-in monitoring validates critical journeys and delivers actionable alerts—not data overload.

### Built for developers & agents

Monitoring that feels like writing application code. CLI, Git, and API-first workflows meet you where you already work—VS Code, GitHub, and your terminal.

### Unified reliability across the SDLC

From staging to production in one platform. Write a test, monitor it in production, trace failures, alert teams—continuity across your entire workflow.

## Three layers of detection. Complete coverage.

From infrastructure health to API reliability to user experience—each layer builds on the last to give you full-stack visibility.

#### Uptime Monitoring

Foundation Layer

Fast, reliable health checks for your infrastructure. Monitor endpoints, ports, DNS, and scheduled jobs with sub-second precision from 20+ global locations.

URL Checks TCP Checks DNS Checks Heartbeat Checks

#### API Monitoring

Service Layer

Validate your APIs are returning correct data with programmable assertions. Test authentication, response schemas, and chain multi-step workflows.

REST & GraphQL Schema Validation Multi-step Flows Auth Testing

#### Browser Monitoring

Experience Layer

Monitor complete user journeys with real Chromium browsers. Catch client-side errors, visual regressions, and performance issues your users would experience.

## Alert the right people, at the right time, with all the right context.

When failures happen, get exact details: which flow failed, which step, which location—plus screenshots and traces. Route alerts to Slack, PagerDuty, OpsGenie, or any webhook.

## Resolve issues faster with deep debugging tools.

Every failure comes with the full picture: screenshots, video replays, traces, and AI-powered analysis to pinpoint root cause.

## Proactive monitoring built for modern teams

Join 40,000+ developers using Checkly to catch issues before users do.
