Appium vs Kobiton

Free and open source

From $50 per month (indicative entry plan)

Free. The real cost is the device lab or device-cloud subscription you run it against.

Priced by device minutes and concurrent sessions; the on-premise hybrid option is licensed separately.

• One API and one test suite for both platforms, in the language you already use.
• Every device cloud supports it, so you stay portable.
• No modification to the app under test — you test the same binary you ship.

• Hybrid model lets you keep sensitive devices in-house while using one interface.
• Manual session recording converts into Appium scripts, shortening authoring.
• Cheaper than the top-tier enterprise clouds.

• Notoriously slow and flaky compared to the native frameworks it wraps.
• Setup is a genuine project: drivers, Xcode, provisioning, Android SDK, versions.
• Debugging failures across the Appium/driver/device layers takes real expertise.

• Smaller device catalogue than BrowserStack or Sauce Labs.
• Generated Appium scripts still need substantial cleanup.
• Mobile only.

Teams that must cover iOS and Android from a single suite and can absorb the setup cost.

Mobile teams that want a device cloud but must keep some devices on premises.
