• 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 edition is unusual in the low-code segment and removes lock-in anxiety.
• 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.

• Natural-language authoring is only approximately natural; you still learn a grammar.
• Smaller community than the established low-code vendors, so troubleshooting is slower.
• The self-hosted edition trails the cloud on features.

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

Teams that want low-code authoring but refuse to put their entire suite in a proprietary cloud.
