I wanted to try Insomnia, but could not install their deb package on my Debian: it depended on a "libappindicator3-1" which is not available in my current release. I'll stick to basic CLI tools when I experiment with web APIs.

The Swagger editor doesn't support OpenAPI 3.1 either, which is surprising since the OpenAPI spec was initially ported from the Swagger format.

That "libappindicator" library being dropped isn't the first time there were problems. The article in yesterday's Steam/Proton post also mentioned it (https://news.ycombinator.com/item?id=30490570). And in any case it seems like it's either considered feature-complete or abandoned, there have been no code-related commits for 12 years now (per https://bazaar.launchpad.net/~indicator-applet-developers/li...).

I raised an issue for this a while ago. Insomnia uses the Swagger UI library, which also (bizarrely) doesn't support 3.1, so Insomnia is blocked until that library is updated.
