You could have a look at EteBase [1], which was recently featured on HN. I haven't tried it myself, but I'm looking to build my applications in a similiar style.

Yeah I chatted with Tom (primary guy behind Etebase) the other day, definitely passionate about this space and knows what he's doing.

Etebase didn't exist earlier this year when I wanted to build Portabella, but I think it's a great option for many platforms.

How many Alex's are building Portabella? ;-)

[alexh1]

Haha my bad, responding off mobile vs. desktop

Userbase seems to be a similar solution https://userbase.com/

Or RxDB https://rxdb.info/ which also supports edits on multiple tabs.

IMO RxDB isn't a competitor here, we're talking about end-to-end encrypted solutions, RxDB is just a way of syncing JSON documents.

In that sense Firebase, Parse, deepstream.io all handle that problem as well.

What you want though is to operate without seeing your customers data, much more ethical in that you'll never be tempted to sell your users data
