Boop

Boop is a macOS‑only utility that provides developers with a simple, scriptable scratchpad for handling plain‑text data. Users can paste snippets such as JSON, XML, JWTs, or other strings and apply transformations without leaving the desktop, avoiding the need to copy sensitive information into external web tools.

The application ships with a collection of built‑in JavaScript actions for common tasks—formatting, decoding, hashing, and more—while also allowing users to add their own scripts to perform custom processing. Scripts run inside a native Swift shell that embeds a JavaScript engine, giving the tool a lightweight, native feel while leveraging the flexibility of JavaScript.

Boop is released under an open‑source license, is free to use, and targets developers who need a quick, local workspace for ad‑hoc text manipulation and automation.
