Thunder Client

Lightweight REST API client inside VS Code and JetBrains IDEs

About Thunder Client

Thunder Client is a REST API client that runs inside VS Code and JetBrains IDEs so developers can build, test and share API collections without leaving their editor. Collections are stored as local files for Git-based collaboration, data stays on the user's machine, and it also works in editors such as Cursor and VSCodium, with enterprise options like SSO and secrets-manager integration.
