After weeks of writing, researching and hopefully enough proofreading, we just launched a living collection of practical guides on leveraging headless browser tools (starting with Puppeteer and Playwright) for testing, monitoring, scraping, performance measuring and more.

You hear about APIs (application program interfaces) everywhere now, and even if you don’t know what one is, you’ve probably heard the term more than once. In this article, we cover a few API basics, and we talk a bit about why you should use API monitoring if you publish or have an API that is critical to your business.
