Appium vs WebdriverIO: open-source mobile automation tools compared

Metrics as of , from the GitHub or GitLab API of each repository. Refreshed monthly.

Summary

Appium: WebDriver-based automation framework for mobile, desktop and IoT apps, extended through platform drivers, client libraries and plugins.

WebdriverIO: Node.js framework for browser and mobile test automation over WebDriver, WebDriver BiDi and Appium.

Both are listed under Mobile automation. The table gives repository metrics from the GitHub API with their fetch date, then the documented facts used for every comparison in this category, each linked to the README or docs page it comes from. A cell reads "not documented" when the fact was not found in the project's documentation (2 of 14 fact cells here); that does not mean the feature is absent.
