API Client Desktop
api-client-desktop.exe is safe. The official desktop API client from the vendor manages and tests HTTP requests locally, with environment handling, authentication, and response logging.
api-client-desktop.exe is the desktop companion for API development, enabling you to build, send, and test HTTP requests against REST, GraphQL, and other API endpoints directly from a dedicated app. It manages environments, authentication credentials, request histories, and response logs, providing a local toolkit to design, debug, and automate API workflows.
api-client-desktop uses a modular core with a request runner and UI thread. Requests execute in isolated workers, with responses parsed, cached, and shown in a structured panel. It supports OAuth, API keys, and token refresh within a secure local environment.
Quick Fact: api-client-desktop supports environments, collections, and code snippets for multiple languages, helping developers prototype requests faster.
