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; WSO2 API Manager the free open source distribution does not include a subscription to the WSO2 Update service, so continuous improvements and security patches require a paid subscription
  • They diverge on capability: Selenium covers W3C WebDriver, WSO2 API Manager covers API Gateway.
  • Prices and features above were last checked on 30 August 2026.

Selenium

  • Flaky tests are the standing complaint: explicit waits and synchronisation are the tester’s job, where newer tools handle it automatically
  • 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

  • The free open source distribution does not include a subscription to the WSO2 Update service, so continuous improvements and security patches require a paid subscription
  • A commercial production licence is not part of the free download and comes only with a subscription
  • No subscription price is published; Basic Support and Enterprise Support both require contacting sales for a quote
  • 24x7x365 coverage requires Enterprise Support; the general query SLA is one business day
  • A Customer Success Manager is a paid optional add on covering business hours only
  • Consulting services and WSO2 Private Cloud hosting are quoted separately

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.

WSO2 API Manager: How is WSO2 API Manager priced?

WSO2 API Manager pricing is not published on their website. As an enterprise API management platform, pricing is custom-quoted based on deployment model and organizational requirements.

Source
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.

WSO2 API Manager: Does WSO2 API Manager offer different pricing for on-premises versus cloud deployments?

WSO2 API Manager supports multiple deployment options including on-premises and cloud, but pricing structures for different deployment models are not publicly disclosed.

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.

WSO2 API Manager: What deployment flexibility does WSO2 API Manager provide?

WSO2 API Manager enables flexible deployment on-premises or in cloud environments, but specific pricing tiers for each deployment model require contacting WSO2 sales.

Source
WSO2 API Manager: How would I request a WSO2 API Manager pricing quote?

Organizations can request pricing quotes by contacting WSO2 sales through their website. Custom quotes depend on API volume, deployment model, and feature requirements.
