Maybe using a tailscale funnel would be a good option for you? I use one for a webdav setup to get around CF’s 100mb limit on uploads when clients won’t chunk their data properly. It was fairly easy to set up and works perfectly.

I’ve been using Floccus extension for a year or two and love it. Everyone of my browsers is supported (except for Orion), synced using my nextcloud setup, and is easy to set up. Can’t complain.

That is an option I’ve been thinking about but I’ve never used it, I’m not a dev. Maybe I’ll look at it more seriously since it does sound like what would work best, I’d really apprecieate the versioning. Thanks!
