The short version

  • Each has a real cost: Selenium flaky tests are the standing complaint: explicit waits and synchronisation are the tester’s job, where newer tools handle it automatically; Spring Cloud Gateway released under the Apache 2.0 license, free and open source with no commercial tier
  • They diverge on capability: Selenium covers W3C WebDriver, Spring Cloud Gateway covers Routing.

  • 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

Selenium: Is Selenium free?

Yes, open source with no licence fee. Paid costs come from grid infrastructure or services like BrowserStack.

Spring Cloud Gateway: Is Spring Cloud Gateway free?

Yes, Spring Cloud Gateway is free and open-source software. It is part of the Spring ecosystem and available through GitHub repositories with open-source dependencies like spring-cloud-starter-gateway-server-webflux and spring-cloud-starter-gateway-server-webmvc.

Selenium: 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.

Spring Cloud Gateway: What enterprise support is available for Spring Cloud Gateway?

Tanzu Spring provides optional enterprise support including Day 0 access to security patches for organizations requiring guaranteed support, but specific pricing is not published on the Spring Cloud Gateway project page.

Source
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.
