Checkly CLI 10: see what a deploy will change before it happens — permalink

Before checkly deploy applies anything, it now shows you exactly what will change. If someone edited a check in the web app, the CLI can copy those edits back into your code, so you don't overwrite them by accident. Want to be strict about it? Add --fail-on-drift and the deploy stops if it would overwrite web app edits.

CLI 10 also brings a few quality-of-life updates. checkly login now works over SSH and for AI agents. Cancelling a test session also skips queued checks of every type. Checks that are already running finish. With CLI 10.1.0 and GitHub Action v1.2.0, the Re-run button on a Checkly GitHub Check re-runs your CI job.

Before you upgrade: CLI 10 has breaking changes. Deploys no longer start check runs unless you add --schedule-on-deploy. AgenticCheck and other deprecated APIs are removed. The release notes have the full list. Your first deploy after upgrading may show many updates. That's expected.

Upgrade with npm install -D checkly@latest.

A checkly deploy preview with a line-by-line diff for one Playwright check: a tag that is live in Checkly and would be removed, the tag the code adds, and a changed code bundle

Save your filters as views — permalink

Save any set of filters as a view. Views show up as tabs above Monitors and Test sessions, and you can keep them private or share them with your team. They replace the traffic-light tiles on the home dashboard, so the counts you see always follow your filters.

Finding the right checks is easier too. Monitors, Heartbeats and Test sessions get a new filter builder with and/or conditions. Reporting gets the same filters and views, plus a Chart view that compares up to 12 checks side by side.

Building a Monitors filter for Playwright checks with two tags and saving it as a Playwright Promo view, which then appears as a tab next to All, Passing, Degraded and Failing

AI Assistant on all paid plans and trials — permalink

The AI Assistant is now available on every paid plan and during trials. Describe what you want to monitor, and it tests the check before it creates it, so you go from a prompt to a working check.

Each new conversation uses one AI invocation. Trials now include 20 invocations, up from 10.

Automatic check repair (Beta) got smarter too. You can now start a repair yourself, Rocky won't make a repair that would weaken a check, and every repair shows up in the check's timeline.

The AI Assistant planning monitoring for three Acme sites: the prompt asks for 200 responses and TLS expiry warnings every 5 minutes from US East and Frankfurt, and Rocky AI replies that it will check the sites and come back with a plan

Also shipped — permalink

  • New IP addresses for us-west-1: from November 16, checks in us-west-1 (N. California) also run from new IP addresses. If you allowlist Checkly IPs, add the new ones and keep the old ones. If you sync from the static IPs API or allow Cloudflare verified bots, you don't need to do anything.
  • Account security: a new Security page lets you change your password, sign out other sessions and set up MFA.
  • Team admin: owners can turn off SSO auto-join, remove members or change roles in bulk, and see pending invites. Invites now show the one sign-in option that fits the invited person, with their email already filled in.
  • Service API keys on Starter and Team: account-level API keys are no longer Enterprise only. Starter gets up to 3 and Team up to 20, so your CI and agents don't need a personal key.
  • Autocomplete for any package: the code editor now knows the types of any package your check imports, at the version it runs with.
  • Playwright reporter 1.14 and 1.15: support for Playwright 1.64, Core Web Vitals collected from your own CI, and no more npm audit warnings.
  • Usage for contract customers: the Usage tab now covers limit-based and credit-based contracts, breaks usage down by uptime monitors, status pages and alerts, and can show several accounts at once. Usage API v2 (Beta) gives you the same data.
  • Terraform, Pulumi and Bun: Terraform and Pulumi can now manage v3 status pages, maintenance windows and FlatBuffers gRPC monitors. Playwright Check Suites can run on Bun 1.4.
