Does it have feature parity with Element yet?

Not yet. It's in beta.

EDIT: Nheko is NOT a mobile client.

If you specifically meant mobile, you could have said so. Your statement was, "every other client has even more drawbacks when it comes to E2EE." Nheko disproves that statement. It also suggests that some alternative mobile clients might handle E2EE at least as well as it does. You might want to try them.

By the way, text search with end-to-end encryption happens to be tricky to implement, and Matrix projects aren't funded by corporations with deep pockets. Tempering your expectations regarding development speed is probably worthwhile here.

There definitely was some feature in Element Web that didn't work and told me to use Desktop instead, unless I'm imagining things now.

It's search.

Even in Element, last time I checked, search was incredibly half-baked and mostly useless.

I know you don't want to use Signal, but it actually has searches that function.

Element X works really well but Servers need to additionally run the sliding sync program. They still run normal synapse, but the sliding sync needs to be added. I could not find a list of Servers that have that installed.

Yeah, it's sad to see it in Zoom's hands, but it is still open source and receiving updates.

Yeah its overkill.

Also important things in my opinion:

• spaces
• admin rights management, roles
• group invite links
• device management (logging out a lost phone etc.)

I think a slimmed down Element with a selfhosted matrix server and no federation is the best for companies

Its crazy how Tech Giants burst out chat apps like nothing.

Having a good client based on Conversations with some stuff added would cost nothing.

The server is not hosted on premise and the team will exchange communication that requires to remain private. That's why I really need E2EE for everything (and why RocketChat is not an option as E2EE is not fully implemented).

There are many options to choose from.

SimpleX is supercool and the best for normal anonymous messaging. Not for companies, school, etc.

But where did those `` jitsi-meet://` links come from?

The calls generated inside rocket.chat are supposed to be handled by the rocket.chat app, everything else it doesn't get involved with.

(I wrote this integration so I'm legitimately interested in how it could be better)

Are you saying you want encrypted text chat? Or do you want voice or video too?

I wouldn't obsess too much about e2ee once there are that many client os's and apps involved, if the server is self hosted. There will be plenty of other points of vulnerability regardless, including careless humans at the endpoints. It's not really possible to achieve security by just choosing the right software. Real opsec is much more complicated.

Molly or Signal-FOSS on Android, flare on Linux.

Flare is incomplete and the others are softforks though. Molly not so much, they support multiple phones / tablet. The Desktop client is bad.

What do you mean by "independent clients" - multi device login?

There's Wire, but it still resembles Signal more than Slack. But apparently they've put some work into making it self-hostable.

Matrix is still probably the closest thing to Slack, Discord etc that actually has functioning E2EE, but also includes cloud synchronization when people can remember their keys.
