10 Postman alternatives you should know about

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 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 10 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.

Insomnia


Website: insomnia.restPricing: 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 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.

  • 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

Insomnia Cons

  • You cannot write tests for standard requests. Testing capabilities of Insomnia are only available to Design Documents (API specs written in Open API format).



Hoppscotch


Website: hoppscotch.ioPricing: Free & Open source

Hoppscotch is an open source Postman alternative. It is available via browser and does not require any account so if you are looking for an online Postman alternative, you should definitely check out Hoppscotch. Open hoppscotch.io, and you can start sending requests. Moreover, Hoppscotch offers dedicated UI for Restful, GraphQL, and Web socket connections. You can easily send requests to APIs in different environments using Hoppscotch’s Environment and Environment Variable feature. Hoppscotch’s approach to testing is similar to Postman and Insomnia, a simple code editor to write test cases in Javascript using Hoppscotch’s testing framework.

Hoppscotch, a Postman HTTP client alternative

Hoppscotch’s Pros

  • Dedicated GUI for Web socket allows you to send messages to Web sockets
  • Dedicated GUI for GraphQL APIs allow you to explore GraphQL schemas and send requests easily

Hoppscotch’s Cons

  • It’s still the early days of Hoppscotch, so there is not much documentation
  • While testing Hoppscotch, we noticed some bugs in UI


Paw


Website: paw.appPricing: $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.

Paw, a Postman HTTP client alternative

Paw’s Pros

  • The native Mac app is fast
  • Paw is extendable using 3rd-party extensions

Paw’s Cons

  • Does not offer a free plan



Thunder Client


Website: thunderclient.ioPricing: Free

Thunder Client is a Vscode Postman alternative since it runs as a Visual Studio Code extension (not open source) and has focused on being a simple and efficient HTTP client while building or integrating with APIs. It supports collections as a way to group relevant requests. Moreover, ThunderClient supports the concept of Environment and Environment Variables to store and re-use values within multiple requests. Finally, ThunderClinet offers a UI that you can use to set the expected response code, response time, and response body for testing APIs.

Thunder Client, a Postman HTTP client alternative

Thunder Client’s Pros

  • It’s free

Thunder Client’s Cons

  • Only available as a VScode extension



Postcode


Website: Github/PostcodePricing: Free

Similar to Thunder Client, Postcode is a fast Vscode Postman alternative. Unlike Thunder Client, Postcode is open source. Postcode UI is very similar to Postman which makes it easy for new users to start using this tool. It supports both RESTful and GraphQL APIs, however the GraphQL support lacks query completion and schema explorer. When it comes to authorization, Postcode only offers Basic Auth and Bearer Token.

If you’re using Postman to send basic HTTP requests, you can easily rely on Postcode to do the same but without leaving your Vscode. That said, if you’re after a fully-fledged API client, please consider other options in this page.

curlx


Website: curlx.devPricing: Free

Curlx, as you might have already guessed it, is a supercharged cURL. It’s cURL with the goodness of Postman, for the terminal lovers. Shivkanth Bagavathy, the creator of Curlx, has made a great decision (in my opinion) to follow cURL’s syntax so if you know how to use cURL, you’re going to feel at home with Curlx.

History and Collections makes CurlX is a supercharged cURL. Access past requests using the cx history command and organise requests into collections using the cx collections command.

Curlx uses your disk to store the data in JSON format whcih makes it super easy to version control your data, and share with your colleagues.

curlx, a Postman alternative


Curlx Pros

  • Free & open source
  • Follows cURL syntax which makes it easy to use
  • Local storage


Curlx Cons

  • Requires Node.js runtime to work, distributed via NPM
