• Shared vocabulary between product, QA and engineering when the practice is actually followed.
• Scenarios double as living documentation that stays honest because it executes.
• Available in every major language.

• Self-healing genuinely reduces maintenance on UIs that change often.
• Auto-captured visual, performance and accessibility signals on every run without extra setup.
• Very little infrastructure to own — no grid, no runners.

• Almost always adopted as a syntax rather than a collaboration practice, at which point it is pure overhead on top of your real tests.
• The step-definition layer is a second codebase to maintain and refactor.
• Gherkin obscures technical detail that developers need when a test fails.

• Cloud-only. If your application is not reachable from mabl's infrastructure, the setup gets complicated.
• Complex conditional logic hits the ceiling of the low-code model.
• Opaque pricing and a substantial minimum commitment.

Teams genuinely practising BDD with three-amigos sessions, not teams who just want prettier test names.

Mid-market teams that want broad automated coverage without hiring an automation team.
