Back in 2012, when Abhinav Asthana released the first version, Postman was a simple HTTP client available as a Chrome extension. Fast forward to today, Postman became a collaboration platform for API development. Postman features include but not limited to: HTTP client, tools for API testing and API monitoring, mock API servers, and documentation.
Postman offers solutions in different verticals. As a result, it attracts users with various needs. For example, if you are using Postman for API testing, we recommend you to read our best api testing tools as we have listed some of the best API testing tools in the market for you. Moreover, we wrote an in-depth article and compared Testfully as an excellent Postman alternative for API testing and monitoring.
This article lists the top 5 Postman alternatives for sending requests to different types of API, including SOAP, Restful, or GraphQL. We continue to update this article with the latest information about the offered features. Please reach out to us via our contact page for any correction or addition of a new tool.

Website: insomnia.rest – Pricing: Free, Paid plans start at $5 (per month/user)
Insomnia started as an HTTP client, just like Postman itself, and evolved to a tool for API development. It offers features including an HTTP client, automated API testing, and an Open API editor. You can send requests to both local & deployed APIs, define multiple environments, and embed environment variables to your requests. It supports XML, JSON, Form, and many other types of request payload, so it’s easy to construct any request.
- Simple and easy-to-use UI. Unlike Postman, Insomnia offers a simple and elegant user interface.
- Insomnia loads faster than Postman and is more responsive than Postman
- You can organize multiple API services using collections and focus on one at a time.
- You can embed customizable random values to your request

Website: paw.app – Pricing: $49
Paw was available as a Mac-only app for a long time with a $49.99 price tag. On Feb 2021, Rapid API announced that they had acquired Paw and announced the availability of cross-platform Paw applications and a new subscription-based pricing model. Out of the box, Paw does not offer many of the features that Postman offers but don’t let that disappoint you because Paw provides a range of extensions for adding new features. For example, we used a Faker.js extension to generate random data and include it in the request.
- The native Mac app is fast
- Paw is extendable using 3rd-party extensions
- Does not offer a free plan
