The short version

  • Each has a real cost: HTTPie the desktop application is in public beta rather than a finished release; 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.
  • They diverge on capability: HTTPie covers REST Client, Kotlin Multiplatform covers Shared Kotlin logic.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

  • Sending and inspecting HTTP requests from the terminalnot Kotlin Multiplatform
  • A readable alternative to curl for API debuggingnot Kotlin Multiplatform
  • Testing APIs through a graphical clientnot Kotlin Multiplatform
  • Installing through apt, brew or pip in a development environmentnot Kotlin Multiplatform

Kotlin Multiplatform

  • A company with existing separate native iOS and Android codebases wanting to stop duplicating business logic and networking codenot HTTPie
  • A team that wants shared logic but is not willing to compromise on fully native UI per platformnot HTTPie
  • An organisation already using Kotlin on the backend that wants to reuse the same models and validation on mobile clientsnot HTTPie
  • A team evaluating Compose Multiplatform for UI sharing but wanting the option to fall back to native UI per screennot HTTPie

Where each one falls short

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

HTTPie

  • The desktop application is in public beta rather than a finished release
  • Pricing for the desktop and web products is not published, while the terminal client is free and open source
  • The graphical versions are newer than the CLI, so parity between them is not guaranteed

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.
