The short version

Each has a real cost: Appium appium provides no device infrastructure at all, so a serious testing programme needs a separate device cloud subscription or an in-house device lab, both real ongoing costs beyond the free framework.; Kong the Plus plan includes 1M API requests a month and charges $200 a month for each additional million
They diverge on capability: Appium covers WebDriver protocol automation, Kong covers API Gateway.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Appium

Appium provides no device infrastructure at all, so a serious testing programme needs a separate device cloud subscription or an in-house device lab, both real ongoing costs beyond the free framework.
Test flakiness and platform-specific quirks between UiAutomator2 and XCUITest drivers are common, and diagnosing whether a failure is a real bug or a driver timing issue takes real automation expertise.
Setup and environment configuration, especially for iOS with Xcode and provisioning profile requirements, has a steeper initial learning curve than most web automation tools.
Being foundation-governed and community-maintained, there is no vendor SLA or support contract for the framework itself, only for the commercial device clouds built on top of it.
Version upgrades between major Appium releases have historically required driver and client library updates in lockstep, which can break existing test suites if not planned for.

Kong

The Plus plan includes 1M API requests a month and charges $200 a month for each additional million
Plus is capped at 10M requests a month, so growth past that forces an Enterprise contract
Plus limits published APIs to 20 and includes one Developer Portal, with a second at $200 a month
SSO and audit logging are Enterprise only
Enterprise pricing is custom and billed annually
