Thunder Client vs Postman-API testing is an essential part of modern software development, ensuring that application components communicate effectively with one another. Two tools that stand out in this space are Thunder Client and Postman. Both are widely used for testing APIs, but they offer different approaches, features, and user experiences.
In this comprehensive blog post, we’ll explore the key differences between Thunder Client and Postman, compare their features with a detailed comparison table, and examine use cases for each. Additionally, we’ll answer frequently asked questions (FAQs) to help you determine which tool is best suited for your API testing needs.
What is Thunder Client?
Thunder Client is a lightweight API testing extension for Visual Studio Code (VS Code). It’s specifically designed for developers who prefer to stay within their code editor while testing APIs. Thunder Client aims to provide a fast, user-friendly way to perform essential API testing tasks without the overhead of using a full-fledged tool like Postman.
Thunder Client focuses on simplicity, offering core API testing functionalities such as making GET, POST, PUT, DELETE requests, managing collections, and using environment variables. Its deep integration with VS Code allows developers to seamlessly test APIs without switching between applications, making it a highly efficient choice for those who spend most of their time in a code editor.
Key Features of Thunder Client:
- VS Code Integration: A native extension for VS Code, meaning you can test APIs directly from your code editor.
- Lightweight and Fast: Thunder Client is designed to be minimal and fast, focusing on core API testing functionality.
- Collections: Allows you to group related API requests into collections for better organization.
- Environment Variables: Supports environment variables for testing across different environments (e.g., dev, staging, production).
- Request Types: Supports common HTTP methods like GET, POST, PUT, DELETE, and more.
- JSON Response Handling: Quickly view and analyze JSON responses.
- No External Dependencies: Works entirely within VS Code, with no need for external applications.
What is Postman?
Postman is one of the most popular and comprehensive API development and testing platforms available. It offers a GUI that simplifies the process of building, testing, and documenting APIs. Postman supports REST, SOAP, and GraphQL APIs, making it a versatile tool for developers, testers, and product teams.
Postman is known for its extensive feature set, which includes everything from automated testing and API monitoring to team collaboration and real-time documentation. While this makes Postman incredibly powerful, it also means that it can be overkill for developers who need a more lightweight solution.
Key Features of Postman:
- API Request Building: Create and send API requests using a wide range of HTTP methods (GET, POST, PUT, DELETE, PATCH, etc.).
- Collections & Workspaces: Group requests into collections for organization and share them across team workspaces.
- Environment Variables: Easily switch between different environments using environment variables.
- Pre-request & Test Scripts: Automate API workflows with pre-request scripts and test scripts using JavaScript.
- API Documentation: Automatically generate and host API documentation.
- Mock Servers: Create mock servers to simulate API responses.
- Collaboration Tools: Extensive collaboration features for teams, including real-time editing, commenting, and version control.
- API Monitoring: Continuously monitor your APIs for performance and reliability.
- Integrations: Connect Postman with CI/CD pipelines, Slack, GitHub, and other tools.

Use Cases for Thunder Client
1. Developers Working Within VS Code
If you’re a developer who spends most of your time working in Visual Studio Code, Thunder Client is an ideal solution. It allows you to test APIs directly from your editor without the need to switch to another tool. This makes the API testing process more seamless and integrated into your daily workflow.
2. Lightweight API Testing
For developers who need a quick, lightweight solution for API testing, Thunder Client is a perfect choice. It doesn’t have the overhead of Postman’s extensive feature set, making it faster and easier to use for simple testing scenarios. It’s especially useful for testing REST APIs without needing complex workflows or advanced features.
3. Solo Developers or Small Projects
If you’re working solo or on small projects that don’t require extensive collaboration, Thunder Client can meet your API testing needs without the complexity of Postman. You can easily manage API collections, use environment variables, and test different endpoints with minimal setup.
4. Simplified Debugging
Thunder Client’s integration within VS Code allows you to debug and test APIs in real-time while writing your application code. This streamlined workflow is beneficial for developers who want a simple way to test their APIs without leaving their coding environment.
Use Cases for Postman
1. Team Collaboration and Large-Scale API Projects
Postman shines in team environments. If your project involves multiple developers, testers, or product managers, Postman’s collaboration features (shared collections, workspaces, real-time editing, and version control) make it a valuable tool. Teams can work together on API testing and documentation, with the ability to track changes and provide feedback.
2. Comprehensive API Testing
Postman is perfect for teams or individuals who require comprehensive API testing, especially when dealing with REST, SOAP, or GraphQL APIs. The tool supports a wide range of HTTP methods and allows for automation of complex workflows using pre-request and test scripts.
3. API Documentation and Mock Servers
Postman is ideal for projects that require automatically generated API documentation. You can use Postman to create professional-looking documentation that can be shared with team members or clients. Additionally, if you need to simulate API responses during the development process, Postman’s mock server feature can be a valuable asset.
4. Continuous Integration and Monitoring
For projects with a strong focus on continuous integration (CI) and continuous delivery (CD), Postman offers robust integration options. It integrates with CI/CD pipelines, allowing you to automate your API tests and ensure that your APIs perform well under various conditions. Postman’s monitoring feature can also alert you if an API endpoint starts to underperform or fail.
