Insomnia, an API development/debugging/testing tool, has been thoroughly enshittified. It now requires a cloud account to use, even though most of the use is just sending requests from your local machine (to servers often running on localhost too).
Luckily it was OSS so we have a new fork without the cloud “features”: Insomnium
Someone below mentioned [Bruno](https://github.com/usebruno/bruno. It claims to be more lightweight, but still looks like Javascript and so probably Electron?
IDK, I just use curl.
