HTTPYAC

Active

Overview

httpYac is a lightweight, open-source tool for API testing and development that allows developers to create and execute HTTP requests as code stored in simple text files (.http or .rest formats). It functions both as a CLI tool and as a VS Code extension, enabling users to send REST, SOAP, GraphQL, and gRPC requests from either environment. The tool is designed to break free from walled-garden API clients by treating requests as shareable, version-controllable text files that integrate seamlessly with standard development workflows.

Key Features

  • Multi-protocol support - Supports HTTP, REST, SOAP, GraphQL, WebSocket, and gRPC requests
  • Text-based request files - Requests stored in .http and .rest files that can be shared, diffed, and version-controlled like regular code
  • VS Code integration - Native VS Code extension allowing request execution directly within the editor
  • CLI tool - Command-line interface for executing single files or entire folders of request files
  • Authentication support - Built-in support for OAuth2, AWS, Basic, Digest, and SSL Client Certificates
  • Variables and environments - Environment configuration with inheritance from global settings, supporting dotenv and IntelliJ variable formats
  • Response caching - OAuth 2.0 sessions cached in VS Code for streamlined authentication workflows
  • Extensibility - Plugin system allowing community contributions and custom extensions
  • Response reuse - Named request responses automatically added as variables for use in subsequent requests

Alternatives

AppDifference
PostmanCommercial tool with cloud-based collections and team collaboration features, versus httpYac's file-based, version-controlled approach
InsomniaStandalone application with GUI-first design, whereas httpYac emphasizes text-based requests and CLI integration
REST Client (VS Code extension)Simpler VS Code extension with fewer protocol options, lacking httpYac's CLI capabilities and plugin system
Thunder ClientVS Code extension focused on UI-driven request building, contrasting with httpYac's code-first methodology

Reputation

httpYac is recognized as a developer-friendly alternative to traditional API clients, praised for its lightweight design, open-source nature, and seamless integration with version control systems. The tool appeals to developers who prefer working with text-based configurations and CLI workflows. Strengths include extensibility through plugins and support for multiple protocols; potential limitations include smaller community compared to established tools like Postman and less extensive documentation for advanced use cases.
