Postman is known for its robust capabilities and user-friendly interface, making it a preferred choice for both individual developers and large teams.
With Postman, users can create and send HTTP requests to APIs, inspect responses, and automate testing workflows. It supports various types of API testing, such as REST, SOAP, and GraphQL, and offers features like collections, workspaces, and collaboration tools for team-based projects.
Key Features of Postman:
- API Request Building: Create and send HTTP requests with various methods (GET, POST, PUT, DELETE, etc.).
- Collections: Group related API requests into collections for better organization and reuse.
- Pre-request Scripts & Tests: Add JavaScript code to run before and after requests, enabling dynamic testing and automation.
- Mock Servers: Create mock servers to simulate API responses during development.
- Environment Variables: Set up environment variables to run tests in different environments (e.g., staging, production).
- Collaboration Tools: Share collections and collaborate with team members.
- API Documentation: Automatically generate and host API documentation based on requests in your collection.
- API Monitoring: Set up automated monitoring to ensure APIs remain functional.
What is Bruno?
Bruno is a relatively new, open-source API testing framework designed for developers who prefer a code-centric approach. Unlike Postman, which is GUI-heavy, Bruno emphasizes a minimalist, file-based, and text-driven approach to API testing. It’s built specifically for developers who are comfortable with a text editor and prefer to work directly with code.
Bruno leverages YAML and Markdown for defining API requests and offers native support for source control (e.g., Git), making it a natural fit for teams that want to version control their API testing along with their codebase. Bruno is lightweight and built with simplicity in mind, making it an attractive option for developers who don’t need the extensive feature set that Postman offers but want a straightforward, code-driven workflow.
Key Features of Bruno:
- YAML-based Request Definitions: Use YAML files to define API requests, making it easy to version control and share API tests.
- Text-Driven Workflow: Bruno focuses on a code-first approach, ideal for developers who prefer working in text editors like VS Code.
- Open-Source & Lightweight: Bruno is open-source, lightweight, and designed to fit into a developer’s existing workflow with minimal overhead.
- Version Control Integration: Native support for version control systems like Git, allowing easy tracking and sharing of API tests.
- Minimalist Interface: A no-nonsense interface for users who want to avoid the complexity of GUI-driven tools like Postman.
- Free for All Users: Unlike Postman, which has both free and paid plans, Bruno is completely free to use.

For users who want to automate their API tests, Postman offers features like pre-request scripts and test scripts using JavaScript. These scripts can be used to automate workflows, set up continuous integration pipelines, and monitor APIs over time. This makes Postman a solid choice for teams practicing continuous integration/continuous deployment (CI/CD).
4. API Documentation and Mock Servers
Postman is also an excellent tool for generating API documentation. By organizing API requests into collections, Postman can automatically generate easy-to-read documentation that can be shared with stakeholders or published online. Additionally, Postman offers built-in mock server support, allowing teams to simulate API responses during the development phase.
Bruno Use Cases
1. Lightweight API Testing for Developers
Bruno is perfect for developers who prefer to work directly in their text editor (like VS Code) and are comfortable with YAML and Markdown. It offers a streamlined, minimalist approach to API testing, eliminating the need for a GUI and allowing developers to define requests and tests in code, which can be version controlled alongside the application’s codebase.
2. Version-Controlled API Testing
Because Bruno is file-based and integrates natively with version control systems like Git, it’s an excellent choice for developers who want to treat their API tests like code. This makes it easier to track changes, collaborate via GitHub or GitLab, and maintain a history of API tests over time.
3. API Testing Within the Development Workflow
Bruno fits seamlessly into the existing development workflow without requiring developers to switch between a GUI and their code editor. Its focus on simplicity and minimalism means there’s no unnecessary overhead, making it a natural fit for developers who prefer a code-first approach to API testing.
4. Open-Source and Cost-Free
Since Bruno is open-source, it’s a great choice for small teams or independent developers who want a powerful API testing tool without the cost associated with paid services. Developers can also contribute to the tool’s development, customizing it to meet specific project needs.
