• 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.

• An open-source community edition adds a self-hosted option alongside the managed cloud.
• Natural-language steps are readable by product owners.
• Web, mobile and API in one authoring model.

• 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.

• Structured natural-language steps use a defined syntax; plan time to learn it during onboarding.
• The community and cloud editions differ in feature coverage; check the edition against your requirements.

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

QA teams that want readable web, mobile and API automation, with a choice of managed cloud or self-hosted deployment.
