As a small note, Swift is a compiled language. It uses LLVM as a backend, same as Rust and Clang (C/C++/ObjC). It's currently listed under "Web & typed scripting".

I designed it to support both interpreted languages (Python, JS, Ruby, etc.) and compiled languages (Rust, Go, C/C++). It detects languages from flags or file extensions, can compile temporary files for compiled languages, and exposes a unified REPL experience with commands like :help, :lang, and :quit.
Install: cargo install run-kit (or use the platform downloads on GitHub). Source & releases: https://github.com/Esubaalew/run
I used Rust while following the official learning resources and used AI to speed up development, so I expect there are bugs and rough edges. I’d love feedback on: usability and UX of the REPL, edge cases for piping input to language runtimes, security considerations (sandboxing/resource limits), packaging and cross-platform distribution.
Thanks — I’ll try to answer questions and share design notes.
As for Kotlin, it could reasonably be placed under either "Web & scripting" or "Compiled," depending on how it's used. Since Kotlin can also compile to JavaScript, its classification depends on the context. If we're talking about Android development, then Kotlin is clearly a compiled systems language.
To clarify: Swift is a compiled, statically typed systems language, much like Rust, C++, or Go. Its core toolchain (swiftc) compiles code into native binaries.
