• 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.

• Non-developers can read and often write the tests, which matters in QA-led organisations.
• Extends far beyond browsers: databases, SSH, serial, network equipment.
• Extremely stable and well-supported in regulated and telecom environments.

• 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.

• The keyword abstraction fights you once logic gets complex; you end up writing Python behind the keywords anyway.
• Verbose syntax and whitespace-sensitive files that are awkward to review in a diff.
• Feels dated next to modern JavaScript tooling, and hiring is harder.

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

QA-led and regulated organisations where readability by non-programmers is a requirement.
