# What's new in April 2026

Published Apr 29, 2026

## Get started with the Checkly CLI using your agent

The new `checkly init` command sets up Checkly Skills, provides a prompt tailored to your project, and one-shots your monitoring suite with Claude Code, Codex, Cursor, or any other agent of your choosing.

```
# From ~/path/to/my-unmonitored-project/
npx checkly init
```

## Runtime 2026-04 is here

The new runtime is available for Browser and Multistep checks, with upgraded Node.js and Playwright versions and updated built-in dependencies. Upgrade from your account settings; Private Location support starts with agent v7.

## Playwright Check Suites: Bun support and smarter dependency caching

Run suites on Bun from CLI 7.11.0 onwards. Custom package manager versions are respected down to the patch version, dependency caches upload only on successful runs and invalidate automatically when your lockfile changes, and all four package managers show detailed install logs.
