Best Postman Alternative to Test APIs?

Hey Cursor folks, What do you all use for testing APIs? Need something simple and efficient!

This is super simple and very lightweight and my general preference for most things (assuming you mean manually testing):

basically a typescript file with your URLs and payloads, that you can execute directly from a row in the file.

If you want something similar to postman though - there is insomnia and thunderclient which are basically the same thing as postman with very similar ui - thunderclient lives in vscode/cursor though as an extension

Also being fed up with Postman getting bloated and the free plan limits. Been using Apidog for the past month and honestly can’t go back.

It has everything - API design, testing, docs, and debugging all in one place. The free plan is actually usable (unlike Postman’s 25 collection runs/month BS).

Super clean UI, doesn’t lag on my machine, and the automated testing is way better IMO.

how is your experience with thunderclient? the rating on extension store or microsoft store is really bad

Try Apidog. It is an all-in-one API development platform for testing, mocking, debugging, designing, and documenting APIs. Very user-friendly.

I’ve been using Posting for a couple of months now, and it is a good tool.

yeah I still prefer just using rest client - but if you need something very similar to postman and willing to pay, it seems to basically be the same thing just integrated into vscode. Im not a big fan of it but I also didnt like postman.

Try HawkClient: https://www.hawkclient.com/

It’s git-friendly, offline-only free alternative to postman, that stores requests in yaml file on user file-system.

  1. Support team collaboration via git.
  2. Support for CI/CD pipeline integration using hakclient-cli npm package.
  3. API Flows : Support API flows using drag and drop ui similar to postman.
  4. Privacy First: No sign-ins. No user data collection.
  5. Cursor AI compatible : generate request YAMLs with AI, and HawkClient auto-detects changes in real-time.
  6. Test cases via script as well through UI.

I recently came across an introduction video about EchoAPI on YouTube, and its AI features looked pretty interesting. I’ve been using it myself lately, and so far the experience has been quite good — it supports a wide range of API methods. You might want to give it a try as well.
