JetBrains-funded technology for sharing Kotlin business logic across iOS, Android, web, desktop and server

The short version
- Each has a real cost: Bitrise pricing varies by location ($89-99 for Starter, $200-225 for Pro); 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.

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
Bitrise: Does Bitrise have a free plan?
Yes, Bitrise's Hobby plan is perpetually free for solo developers and includes limited build credits for testing.
SourceKotlin 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.
Bitrise: What is Bitrise's Starter plan price and concurrent build limit?
Bitrise Starter costs $89 per month (or up to $99 depending on location) and includes up to 3 concurrent macOS builds and 10 Linux builds.
SourceKotlin Multiplatform: Is there a paid version?
No. It is Apache 2.0 licensed and free, funded by JetBrains as part of the Kotlin project.
Bitrise: What are Bitrise's per-minute build machine rates?
macOS M4 and M2 Pro Large machines cost $0.0096 per minute; Linux Medium costs $0.0044 per minute; Linux Large costs $0.0089 per minute.
SourceKotlin 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.
Bitrise: How much does Bitrise Build Cache cost?
Bitrise Build Cache starts at $600 per month and includes 200 monthly cache invocations per seat for Enterprise plans.
