Our latest runtime, 2024.09 is now available in beta.

2024.09 uses Playwright 1.47.1 and includes new dependencies:

• @clerk/testing 1.3.0

• mailosaur 8.6.1

• gaxios 6.7.1

• @kubernetes/client-node 0.22.0

• mysql 2.18.1

The following dependencies have been removed:

• chai

• chai-json-schema

• chai-string

If you use any of the above packages, we recommend refactoring your checks to use @playwright/test instead.

Performance

We have noticed a performance impact on some fast-running checks when using 2024.09, affecting check duration.

If your browser or multistep checks typically complete within 10 seconds, you might see a slowdown in check duration. Current data indicates a slowdown between 5% and 15%, depending on check configuration.

We are actively investigating performance further during the beta period.

Enabling beta runtimes

To enable beta runtimes on your account, go to https://app.checklyhq.com/settings/account/labs and toggle Beta runtimes to Enabled. You can then select beta runtimes as usual in the account, group, or check settings.
