• One API for web and native mobile, which is rare and genuinely useful if you ship both.
• Vendor-neutral: swap between local, grid and any device cloud by changing config.
• Mature plugin ecosystem for reporting, visual testing and accessibility.

• 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.

• Configuration-heavy compared to Playwright; the wdio.conf.js file becomes a project of its own.
• Inherits WebDriver's flakiness characteristics when used in WebDriver mode.
• Smaller community than Playwright or Cypress, so obscure problems take longer to solve.

• 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.

JavaScript teams that need one framework covering both web and native mobile.

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