Free and open source. The real cost is grid infrastructure or a device-cloud subscription.

Enterprise licensing only, negotiated annually. Six-figure contracts are normal at scale.

• The widest language and browser support of anything in the category, including legacy browser versions.
• A W3C standard, so it will outlive any single vendor. Skills transfer between employers.
• Every device cloud speaks Selenium, which keeps you portable between vendors.

• Unmatched coverage of enterprise packaged software, especially SAP end-to-end processes.
• Model-based design means one change updates every affected test case.
• Risk-based prioritisation is a real answer to eight-hour regression packs.

• No built-in waiting strategy, reporting, parallelism or assertions — expect to assemble and maintain a framework around it.
• Explicit waits are your problem, and getting them wrong is the number one source of flake in real Selenium suites.
• Out-of-process communication makes it slower than Playwright or Cypress.

• Expensive, and priced for organisations with a procurement department.
• Steep learning curve; most customers buy consulting alongside the licence.
• Heavy and slow compared to modern code-first tools for plain web applications.

Enterprises with polyglot teams, legacy browser requirements, or an existing grid investment.

Large enterprises running SAP or similar packaged systems where no open-source tool reaches.
