• 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.

• Smart locators handle everyday UI churn well.
• The escape hatch to real JavaScript keeps complex cases possible.
• Reusable shared steps keep large recorded suites maintainable.

• 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.

• Test logic lives in the vendor's cloud rather than your repository, which complicates review and branching.
• Run-based pricing punishes running the full suite on every commit.
• Post-acquisition roadmap is bound to the wider Tricentis strategy.

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

Teams with fast-changing UIs that need maintenance to stay low.
