Checkly is a code‑first reliability platform that lets developers write, version, and deploy synthetic browser checks, API and uptime monitors as JavaScript/TypeScript, Terraform, or Pulumi. Monitors run from over 20 global locations and integrate with alerting tools and status pages, while private agents and AI‑enhanced skills enable monitoring of internal services and natural‑language check creation.

Problem
Developers and SRE teams often need separate tools for testing, uptime monitoring, alerting, and status communication, leading to fragmented workflows, high maintenance overhead, and delayed detection of issues in production.
Solution
Checkly offers a unified, code‑first reliability platform that combines synthetic browser checks, API and uptime monitoring, alerting, and status page publishing. Users write monitors in JavaScript/TypeScript, Terraform, or Pulumi and deploy them from the CLI to more than 20 global locations in seconds. The platform supports HTTP, HTTPS, TCP, DNS, ICMP, and heartbeat checks, as well as Playwright‑based end‑to‑end browser tests that capture traces, screenshots, and videos for rapid debugging. Integrated alert channels (e.g., Slack, PagerDuty) and customizable status pages provide clear, real‑time incident communication. Private agents enable monitoring of internal services behind firewalls, while AI‑enhanced skills let agents generate or update checks via natural‑language prompts.
Target Audience
Checkly targets engineering teams, SREs, and DevOps professionals who need integrated testing, monitoring, and incident communication for web applications, APIs, and infrastructure.
