Runtime specification

By default, all our runners have their timezone set to UTC, regardless of their location.

Each Browser and Multistep check can use up to 2.9 GiB of memory and 2 CPU cores. This limit applies to all processes spawned by the check, including the browser, the test framework, and the test code itself. The limit is enforced by the runner and is not configurable.

When the memory limit is exceeded, the check will automatically fail with a relevant error message, for example: Your check has reached the maximum memory usage of 2.9 GiB.

These are the currently available runtimes and the included external NPM dependencies.

The packages below are included for setup and teardown scripts as well, with the exclusion of Puppeteer, Playwright and Mocha.

We are planning to deprecate mocha in the future. Please use @playwright/test as a test framework instead.
