# Script Node

> Run custom code in a secure, high-performance sandbox.

Executes JavaScript or Python code in a sandboxed environment. The script receives inputs as variables and returns a string output.

Scripts run in an isolated sandbox powered by WebAssembly, with access to the language’s standard library. No network access and no persistent filesystem – scripts are purely computational – **for now**. Designed for data transformation, validation, formatting, and computation that goes beyond what the transform nodes offer.
