Insomnia.rest generally is my tool: https://github.com/Kong/insomnia

Thunder Client if you like to keep all the relevant requests n data inside the project directory, probably good for teams: https://open-vsx.org/extension/rangav/vscode-thunder-client

With VS-Codium (vscode with the microsoft telemetry scraped out): https://vscodium.com/

curl?

SoapUI open source version works pretty well and does not require a logon to save your projects

I’ll use REST Client in visual studio code when working on Azure functions etc

https://hurl.dev is pretty sweet.

Curl. Or if I need to chain stuff together for auth reasons or whatever, sometimes ill just pop into a python virtualenv and use requests

I’ve recently been looking at Hopscotch: https://github.com/hoppscotch/hoppscotch

But the free version of Postman seems to offer everything we’d want.

Sometimes swagger UI

Insomnia or just plain old cURL

And which ones handle injecting base 64 encoded file content (100MB) into the json body well? I've been using SoapSonar, but I'm having issues with this at the moment.

Depends on what tests I want to do. Sometimes I just make a python script.

Why switch? Postman is still my go-to
