REST Client

REST Client is a Visual Studio Code extension developed by Huachao Mao that enables developers to send HTTP requests and view responses directly within the VS Code editor. It supports RFC 2616 HTTP request format using .http and .rest files, GraphQL queries, cURL commands, multiple authentication schemes (Basic, Digest, SSL Client Certificates, Azure AD, AWS Signature v4, AWS Cognito), environment and file variables, request chaining, cookie management, code generation to multiple languages, and response saving. The extension is installed via the VS Code Marketplace under the identifier humao.rest-client and is widely used as a lightweight alternative to dedicated API clients like Postman and Insomnia.
