It provides a complete environment for executing RESTful requests, as well as specialized support for SOAP, GraphQL, WebSockets, and Server-Sent Events (SSE). Whether you are debugging a simple endpoint or monitoring a live data stream, RePost offers the tools to interact with any backend architecture seamlessly. Organize your workspace with intuitive collections and nested folders, allowing for logical grouping of complex API landscapes. The built-in Network Interceptor enables you to capture real-time traffic directly from your browser, which can then be imported into your collections with a single click. Support for importing industry-standard formats like Swagger, OpenAPI, and Postman ensures you can get started in seconds without manual setup. Take your testing further with a powerful scripting engine. Write pre-request and test scripts to automate workflows, validate responses, and handle dynamic data. Manage multiple environments and global variables to switch between development, staging, and production contexts effortlessly. RePost also features robust cookie management and native support for various authentication methods, including Basic, Bearer, and API Keys. Gain deep visibility into your API performance with detailed timing waterfalls and interactive JSON trees. RePost is built with a "local-first" philosophy; all your collections, environments, and sensitive data stay within your local environment, ensuring maximum privacy and security. With its clean, focused interface and support for five languages, it is the ideal companion for Developers, QA, and Requirements Engineers alike. ⚠️ DISCLAIMER RePost is an independent API testing tool.
