Everything New in Checkly CLI v8 (8 Features in 4 Minutes)

Checkly

Jun 18, 2026

We at Checkly shipped a major CLI v8 release. Here's everything new, and why it's built for your agent.

The CLI v8 expands Monitoring as Code and streamlines your everyday workflows:

Runs TypeScript check.ts files out of the box — no separate Jiti or ts-node setup needed
Auto-loads your.env file for auth via CHECKLY_API_KEY and CHECKLY_ACCOUNT_ID (alongside persistent npx checkly login)
Records test sessions by default on npx checkly test, with a shareable link every run (pass --no-record to opt out)
Ctrl+C now cancels running sessions instead of leaving them burning resources in the background
A new test sessions command to list, inspect, fetch by ID, and watch runs from the terminal
A new npx checkly api command for any of Checkly's ~130 API endpoints, with auth and base URL handled automatically
Engine selection for Playwright Check Suites — Node 22, 24, 26, or Bun 1.3, configurable in code
A new SlackAppAlertChannel construct to define Slack app alerting in code and deploy via the CLI

Upgrade and try it:
npm install checkly@latest
