The short version

  • Each has a real cost: Kotlin Multiplatform it shares logic, not UI, by default, so a team expecting a Flutter-style single UI codebase has to also adopt Compose Multiplatform, which is newer and less proven on iOS than on Android.; PyCharm exact pricing for Pro edition not available on homepage
  • They diverge on capability: Kotlin Multiplatform covers Shared Kotlin logic, PyCharm covers Intelligent code editor.

Where each one falls short

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

Kotlin Multiplatform

  • It shares logic, not UI, by default, so a team expecting a Flutter-style single UI codebase has to also adopt Compose Multiplatform, which is newer and less proven on iOS than on Android.
  • iOS interop relies on Kotlin/Native compiling to a framework consumed from Swift, and debugging across that boundary is more friction than debugging pure Swift or pure Kotlin.
  • Because logic-sharing is the whole premise, teams still need genuine iOS and Android UI expertise on staff; it does not reduce the native skills bar the way a full cross-platform UI framework aims to.
  • Build times and tooling maturity for multiplatform Gradle projects lag behind single-platform Kotlin or Swift projects, and multiplatform-specific build errors are less well documented.
  • JetBrains funds it as part of the broader Kotlin investment, so its roadmap priority competes internally with IntelliJ, Android Studio and other JetBrains commitments rather than having dedicated headcount the way Flutter has at Google.

Answered from the vendors’ own pages

Kotlin Multiplatform: Does Kotlin Multiplatform replace my native UI code?

Not by default. It shares business logic and data layers; UI stays native per platform unless you separately adopt Compose Multiplatform.

PyCharm: How much does PyCharm cost?

PyCharm offers a free Community edition plus a Professional edition with a one-month free trial of Pro features included. Exact Pro pricing is available on JetBrains' buy page.

Kotlin Multiplatform: Is there a paid version?

PyCharm: Is there a free version of PyCharm?

Yes, PyCharm Community Edition is completely free. All new downloads also include one month of PyCharm Professional included free.

Source
Kotlin Multiplatform: Do I need Compose Multiplatform to use it?

No, they are separate. You can share only logic and keep fully native UI on each platform indefinitely.
