What does Thunder Client do?
Thunder Client is a lightweight REST API client that runs directly within your development environment. It lets you test APIs without leaving VS Code or JetBrains IDEs, eliminating the need to switch between applications. You can send HTTP requests, inspect responses, and organize your API collections right where you write your code.
The tool stores all your API data locally, which improves privacy and security compared to cloud-based alternatives. It supports Git synchronization, allowing teams to share API collections through version control. The interface is designed for simplicity with GUI-based testing that requires no scripting knowledge, making it accessible for developers at all levels.
Thunder Client works best for software developers and teams who regularly work with APIs and want to maintain their workflow within their coding environment. It's particularly useful for testing backend services, debugging API integrations, and maintaining shared API documentation through Git repositories. The tool has been adopted by enterprises across various industries for its efficiency and security-focused approach.
