alt Hacker NewsI tried really hard to use Collabora 'web' solution. It is unusable.
For those who don't know: it renders the whole LibreOffice interface on server and passes it to you. Lots of issues with hotkeys on non-standard layouts (I use Dvorak), with language switching, with mouse behavior, with clipboard, ugh. Of course it is hungry for resources. No. This isn't the way.
Are you sure that's not just a VNC-based demo of the desktop version of Collabora Office?
I wouldn't be too surprised if their web version was like that (given how long ago the first version came out), except Nextcloud uses a Collabora-based system for its online editing, and I doubt they'd go with something like that.
There are online ODT editors (e.g. https://webodf.org/demo/ci/wodotexteditor-0.5.9/localeditor....), so even if Collabora's is bad, it wouldn't be too hard to make a better one.
