🤩 Bruno: An IDE for Exploring and Testing HTTP APIs
An open source (though a commercial version is available) Node and Electron-based desktop app for crafting and testing HTTP requests, complex and simple. Think of it as a lightweight alternative to something like Postman.

✌️ jsonrepair: Repair Invalid JSON Documents
This has lots of possible use cases, including dealing with weird JSON coming back from LLMs or non-compliant JSON spat out by poorly built software. You can use it from Node, as a CLI tool, or try a basic version online.
