I use RESTer, a Firefox extension, to test APIs: https://addons.mozilla.org/en-US/firefox/addon/rester/

It's an in-browser equivalent of Postman.

I much prefer the approach of being able to use the browser for things like this. It feels much more lightweight than installing a piece of desktop software.

Yep I’m finally switching off of postman today. I’ve wanted to for a while, but my team at work uses it, and all of our shared stuff is in there.

I’ve been thinking of replacing postman with a clojure project, where you just send stuff to the REPL to call it. You could even set up a little dependency map, so your calls would have built-in behavior like “if the token is expired, grab a new one with user/pass”. And it would be trivial to script endpoint calls together.

If anybody has done something similar, I’d love some tips or ideas

The second they required you to make an account and have your saved api calls on the cloud was when it was over.

When they started uploading things to the server and requiring you to have an account to access the things that they STOLE from your machine without authorization in first place, I uninstall it...

What can go wrong by uploading your things, if you had any passwords or users there that "pinky promise" will not be uploaded, then running AI and maybe oops have a leak and now someone is hitting your production servers?

It was never, ever clear to me why you needed to use Postman instead of Curl

Many, many years ago, I used Postman for the first time, way back when it was a Chrome plugin. As an iOS dev, it was amazing to be able to validate the requests I needed to make outside the context of my code to validate things worked. Until, one day, I wasn't seeing something iterate in the responses I was getting as I expected to. Many cmd+R presses later, I talked to the API team to check logs, and we found that Postman was caching what should have been independent requests. Easily blamed on Chrome at the time, but it was an undocumented and unexpected behavior by Postman, who really should have better handled making each request unique.

I didn't need another reason not to use Postman, but I'll take it. Shame on them for moving in shadows.

Postman used to be a simple tool to make http requests.

Now it is some kind of incomprehensible thing that requires me to log in and create a 'collection' or whatever it was when I just wanted to make a simple call to some api to see what it does.

Like.. wtf. Why did they need to turn it into some monstrosity?

Relying on heavily managed, LLM-driven developer platforms introduces severe data exfiltration risks. These complex environments mostly preferred by newer generations of programmers represent critical supply chain exploitation risks that simply never existed in traditional local setups. The consequences are incidents like recent Binance hack.

If there's ever been a perfect app to vibecode your own replacement, it's postman. Claude can knock out a completely usable competitor in under an hour, I'm sure of it. A day of tweaking and you'll have everything you need.

postman is dying a software company as agents rapidly can write good cli, you can test your backend api points easier with a llm then when postman.

silently installing ai plugins and recording data is really not cool
