About Thunder Client

Thunder Client is a commercial REST API client delivered as an extension for Visual Studio Code, with a newer plugin for JetBrains IDEs. It lets developers send requests and inspect responses without leaving their editor, and it positions itself as a lightweight alternative to larger API clients such as Postman. It also supports GraphQL queries.

API client data is stored locally for privacy, and collections can be saved to a Git repository so teams can share them. Responses can be tested through a GUI without writing scripts, and a command line interface is available. The company is based in Ireland and says the service is built and hosted in the EU. Thunder Client is proprietary software, with documentation, a pricing page and account sign-up on its site.
