"Easy, Fast API Testing in VS Code with a User-Friendly UI"

4.5/5

What do you like best about Thunder Client?

What I like most is how easy it makes API testing. I no longer have to switch between multiple tabs; I can run simple API tests directly in Visual Studio Code, which keeps my development workflow smoother and more efficient.

It is integrated with Vs code which reduces my efforts.

The setup is straightforward, and features like headers, authentication, query parameters, and the request body are clearly organized and easy to manage. Creating and testing APIs also feels more approachable, even for someone who’s just getting started with backend development. I started my journey with Thunder Client, and it genuinely made my work easier when I was first getting into backend development. Review collected by and hosted on G2.com.

What do you dislike about Thunder Client?

Thunder client is a fast and convenient API testing tool, but there are a few areas where it could improve. It’s good enough for completing simple tasks, but for larger API testing work—like handling complex automation and advanced scripting—it starts to feel limited. I started my journey with Thunder client last year, but when I moved into automation, I had to switch to another tool because of those limitations. I think it could improve a lot in this area.

Team collaboration features also aren’t as strong or flexible as in other API testing tools. Managing shared workspaces, syncing changes across the team, and supporting larger collaborative projects could all be improved. Review collected by and hosted on G2.com.

What problems is Thunder Client solving and how is that benefiting you?

For the most part, it solves the tab-switching problem. When I just want to test a simple API, it’s irritating having to bounce between VS Code and Postman for everything, especially if I only need a quick look at the response. It’s lightweight too, so I get results quickly and don’t have to wait minutes just to see what comes back.

It also reduces complexity for beginners. A lot of API testing tools pack in advanced features and complicated interfaces that can feel overwhelming for a new developer. Thunder Client keeps things simple with a clean, user-friendly interface, which makes it easier to understand API requests and responses, headers, authentication, and JSON data formatting. Overall, it helps me move faster during development.

It’s also free, so I don’t have to worry about pricing at all. Review collected by and hosted on G2.com.
