I’ve been using Postman for API testing and development for a while now, but I’m looking to explore some alternatives. Some recent changes to their pricing model and features have me considering other options.
Does anyone have recommendations for good Postman alternatives? I’m particularly interested in tools that:
Have a clean, intuitive interface
Support API testing, documentation, and collaboration
Offer a decent free tier or reasonable pricing
Would love to hear about your experiences with any alternatives you’ve tried!
Hey there! I’ve tried several Postman alternatives, and here are 3 open source/free options that I think are actually better in many ways:
Apidog: This has become my go-to tool recently. While not fully open source, Apidog offers a much more generous free tier than Postman. Some standout features:
All-in-one platform for API design, development, testing, and documentation
Mock servers and automated testing built-in
Better OpenAPI/Swagger integration
More intuitive UI with less resource consumption
Team collaboration features even on the free tier
Bruno: This is super lightweight and runs directly in your browser:
Blazing fast performance (much lighter than Postman)
Progressive Web App that works offline
Support for WebSockets, GraphQL, and multiple authentication methods
100% open source and free forever
Very modern UI with dark mode
Insomnia: Fully open source and quite powerful:
Clean, minimalist interface that’s faster than Postman
You’re definitely not alone in reassessing Postman! Their recent changes have pushed many users to explore alternatives.
When looking for a good Postman replacement, it really depends on your priorities, but here’s my take:
API testing tool that’s going to be secure for your code
Apidog is top notch. It is has a very intuitive interface that does what postman does. One selling point is that the code can be saved locally. You have all these different tools that you need in Apidog. You would like Apidog.
Insomnia: is similar in features. It is an application for Mac, Windows, and Linux. It can handle HTTP requests.
Ultimately, choosing one would depend on how you want your code base to be handled! Postman, put all the code online which might be a violation of your security. Apidog allows you to maintain full control, by being the only one to access the code.
If you’re exploring alternatives for fast, logic-driven testing without the API complexity, you might want to try something like Blah Blah Blah Lite.
It’s a TXT-based reasoning engine that gives you 50 logically coherent answers in one go — perfect for prototyping prompts or logic flows with zero setup.
Open source, plug-and-play with any LLM.
