API checks are monitors that do POST, GET, and other typical HTTP requests. You have full control over the payload, headers, etc. You can also create assertions to check if the response from your API is valid and performant. For billing, we count any HTTP request as a check run. API check runs have a timeout threshold of 30 seconds.

Browser checks are monitors based on Node.js scripts using frameworks like Mocha, Puppeteer, and Playwright. Each browser check uses an actual Chrome browser to execute clicks, fill out forms and validate if these interactions have the correct results. This is also commonly called “synthetic monitoring”. For billing we count every executed script as a check run. Browser check runs have a timeout threshold of 120 seconds.

By signing up for the hobby plan, you get access to almost all of Checkly’s features. You do not need a credit card to get started. You can execute up to 10,000 API and 1,500 browser check runs per month.

The hobby plan is hard-capped at 10k API and 1.5k browser check runs. If you need more, upgrade to the team plan. The team plan includes 50k API and 6k browser check runs with the possibility of prepaying for additional check runs ($0,005 for each browser and $0,0002 for each API check). If you still need more, consider the enterprise plan—the sky is the limit!

Overages apply at $6 for 1k browser and $2.5 for 1k API checks if no prepaid check runs are left.

If there are no prepaid checks left, we bill $0.00025 for every API and $0.006 for every additionally run browser check.
