The short version
- Only Kotlin Multiplatform has a free tier, so it costs nothing to try first.
- 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.; Sencha it is the only commercially licensed framework in this category; a per-developer fee applies where Ionic, Capacitor, NativeScript, MAUI and Kotlin Multiplatform all cost nothing.
- They diverge on capability: Kotlin Multiplatform covers Shared Kotlin logic, Sencha covers Enterprise grid components.
- Prices and features above were last checked on 1 September 2026.

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.
Sencha
- It is the only commercially licensed framework in this category; a per-developer fee applies where Ionic, Capacitor, NativeScript, MAUI and Kotlin Multiplatform all cost nothing.
- Its mobile story is secondary to its web-grid heritage, so teams primarily building consumer mobile apps get less mobile-specific benefit than from a purpose-built mobile framework.
- Idera has acquired numerous developer tool brands, and product investment across a large portfolio company is not guaranteed to prioritise any single acquired product indefinitely.
- The developer hiring pool for Ext JS specifically has shrunk as React and Angular dominate new development, making it harder to staff new projects.
- Community plugins, tutorials and Stack Overflow activity are far thinner than for any free, widely adopted framework in this category, so troubleshooting relies more on paid support than public resources.

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.
Sencha: Is any part of Sencha free?
A 30-day evaluation trial is available; production use requires a purchased per-developer licence.
Kotlin Multiplatform: Is there a paid version?
No. It is Apache 2.0 licensed and free, funded by JetBrains as part of the Kotlin project.
Sencha: Who owns Sencha?
Idera, Inc., a private software holding company that also owns Xray and Xporter, two other Atlassian ecosystem products.
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.
Sencha: Is Sencha mainly a mobile framework?
No. Its core strength is data-heavy enterprise web UI, particularly grids; mobile packaging is a secondary capability.
