Top 5 Open Source Postman Alternative
Postman is a great tool when trying to dissect RESTful APIs made by others or test ones you have made yourself. It offers a sleek user interface with which to make HTML requests, without the hassle of writing a bunch of code just to test an API's functionality.
METHOD
Postman provides many endpoint interaction methods. Below are some of the most commonly used ones, including those features.
- GET: Get information
- POST: Add information
- PUT: Replace information
- Patch: Updates specific information
- Delete: Deletes information
COLLECTION
Postman offers the possibility to group different requests. This feature is called a "collection" and helps you organize your tests.
These collections are folders that store requests and can be configured the way your team wants. It is also possible to export them.
ENVIRONMENT
Postman can also create different environments through the creation / use of variables. A URL variables that target different test environments (dev-QA). This allows you to run tests in different environments using existing requests.

FLOW THROUGH APIs
HTTPie is making APIs simple and intuitive for those building the tools of our time.
APIs are hard made human
It all started with a problem: API testing was slowing us down, and the available solutions were tediously inefficient. We decided to scratch our own itch and build a better solution—one that helped us keep our flow. That humble tool, which we open-sourced, quickly captured developers’ hearts and rapidly became one of the top projects on GitHub.
We’re now building on top of that success. The power and virtually limitless potential of APIs captivate us. There’s still a lot of work to be done to unleash them fully. We’re on a mission to make APIs simple and intuitive for all those building the tools, apps, and technologies of our time. We truly believe that APIs have the capacity to make our world a better place.
Applying the same principles that made our original tool so beloved, we're building a platform for API development. The vision is an uncompromisingly simple and human-centric yet powerful ecosystem of tools and services helping developers and companies throughout the API lifecycle, especially in places where humans and APIs intersect.

❤️ Lightweight: Crafted with minimalistic UI design.
⚡️ Fast: Send requests and get/copy responses in real-time.
HTTP Methods
GET - Requests retrieve resource information
POST - The server creates a new entry in a database
PUT - Updates an existing resource
PATCH - Very similar to PUT but makes a partial update on a resource
DELETE - Deletes resource or related component
HEAD - Retrieve response headers identical to those of a GET request, but without the response body.
CONNECT - Establishes a tunnel to the server identified by the target resource
OPTIONS - Describe the communication options for the target resource
TRACE - Performs a message loop-back test along the path to the target resource
<custom> - Some APIs use custom request methods such as LIST. Type in your custom methods.
