Zippedscript -

The most native implementation of ZippedScript is found in Python. Since Python 2.3, the interpreter has supported zipimport.

ZippedScripts allow developers to ship a "single-file" application. Instead of asking the end-user to install Python, pip, and various libraries, the developer can bundle the interpreter logic and dependencies into one zip file. This is the logic behind tools like PyInstaller (which creates a self-extracting archive) and Shiv (which creates self-contained Python zipapps). zippedscript

Because the entire script and its environment are timestamped in one archive, you can archive old ZippedScripts and roll back instantly. No more "it works on my machine" arguments—the machine is inside the zip. The most native implementation of ZippedScript is found

On the target machine (which may have no internet access), the user runs: The zsc runtime does the following in milliseconds:

zsc run app.zipscript --arg1 value1

The zsc runtime does the following in milliseconds:

If the target machine lacks the required runtime (e.g., Python 3.11), the ZippedScript can include a static runtime shim—a tiny, self-contained binary that bootstraps the interpreter via WASM (WebAssembly). This makes ZippedScript truly universal.

On resource-constrained devices (IoT, Raspberry Pi, CDN edge nodes), installing Python or Node.js is often impractical. ZippedScripts compiled to WebAssembly run directly in Wasm runtimes like Wasmtime or Wasmer, consuming less than 10MB of RAM.
