May 31, 2025What is the best free API for testing?
ReqRes provides a free hosted REST API with real endpoints, authentication, persistent data, and request logs. Unlike static mock APIs, it returns real HTTP status codes and supports CRUD operations, making it ideal for Postman, Playwright, and CI testing.

How do I test an API without a backend?
Use a hosted test API like ReqRes. Get a free API key, add it as an x-api-key header, and send requests to endpoints like https://reqres.in/api/users. No backend setup, database, or server required.

What is the difference between a mock API and a real test API?
A mock API intercepts requests in your test code and returns hardcoded responses. A real test API like ReqRes actually processes requests over HTTP, returning real status codes, headers, and response times. Real test APIs catch issues that mocks miss, like auth failures, network errors, and payload validation.

r/softwaretesting on Reddit: Free / Open Source Alterative to Postman
December 12, 2023 -
Hello All,
I know there is a bunch of asks for an alternative to postman, but none that relates to my request per say or at least that I can find. I am currently using the free version and now being limited on requests and my company is not interested in doing the paid version anytime soon. I am looking for something free / open source with more and / or unlimited requests if possible. I like Postman, but they are constantly changing up things or limiting the free version more and more. The biggest thing for me right now is certain features and being limited of requests i can execute per month.
One of the parts I use alot is their Collection Runner feature. I like the simplicity use of it and i can use excel spreadsheets to add / generate data and map that data and run tons of calls without having to create and match the same behavior with a bunch of steps. Does anyone know of another piece of software that has something similar with collection runner type feature?
Thanks for your time.
-edit: thank you all for the suggestions. I’ve been messing with a lot of them but seems Bruno has been the one that offers what’s I am looking for.

Apache JMeter. The only cons I feel is that : Initial learning curve for a Less-code tool. Dated UI. It doesn't have a "workspace" for collaboration, but the JMX file used by jmeter is basically an XML that git version control can support. Other than that, it is a good tool. Pros: You can chain requests. You can read CSVs. You can establish DB connections. (Postman doesn't have this) You can write pre/post scripts. Environment variables in postman = User defined variables in jmeter Uses local storage (file) instead of cloud base workspace. It's free/open-source, and you'll get lots of examples on the web. Supports groovy and Java in scripts (others also, but I'm not aware) Increase the thread count and you can do a load test as well. You can even record API workflows in jmeter.
