THUNDER CLIENT LIMITED

Thunder Client Limited is the creator of the popular Thunder Client extension for Visual Studio Code, a lightweight yet powerful REST client designed to make API testing fast and intuitive. Since its launch in 2021, the tool has amassed over five million downloads across more than a hundred countries and is trusted by Fortune 500 firms, banks, financial services, technology companies and retail giants for everyday API development work.

The extension offers a full suite of features that streamline the testing workflow: users can organise requests into collections, manage multiple environments, and store all data locally on their device. Built‑in Git sync lets teams version‑control their request libraries, while the scriptless GUI enables rapid validation of responses without writing code. For organisations that require automation, Thunder Client’s CLI integrates with CI/CD pipelines and produces detailed reports. An upcoming AI integration, powered by the MCP Server, promises AI‑generated tests to further accelerate development.

By focusing on simplicity, speed and collaboration, Thunder Client equips developers, QA engineers and DevOps professionals with a reliable, easy‑to‑use solution for testing APIs directly within their favourite editor.
