- Setup involves drivers, versions and grid infrastructure that Playwright and Cypress bundle away
- Slower to run than tools that talk to browsers over a debugging protocol rather than WebDriver

Answered from the vendors’ own pages
Keil MDK: Does Keil MDK have a free version?
Yes, Keil MDK Community Edition is free for non-commercial projects. Essential and Professional editions are available as monthly or annual subscriptions.
SourceSelenium: Is Selenium free?
Yes, open source with no licence fee. Paid costs come from grid infrastructure or services like BrowserStack.
Keil MDK: How much do Keil MDK paid editions cost?
Specific pricing for Essential and Professional editions is not published on the main site. Rates are available from the Arm Developer Tools store or by contacting Arm sales.
SourceSelenium: Selenium or Playwright?
Playwright handles waiting automatically and is faster to set up, which removes most flakiness complaints. Selenium wins on language breadth, browser coverage including Safari, and existing suites you already have.
Selenium: Is Selenium still relevant?
Yes. Its WebDriver protocol is a W3C standard implemented by every major browser, and very large existing suites are not rewritten cheaply.
