Yes, they have E2EE, but it comes with some limitations in the features they're able to provide.

Like what? I like it a lot...

Replying to your latest comment here:

What do you mean by syncing? Happy coder syncs sessions between all my happy coder clients. I can even see in real time how happy coder in my browser's conversations progress as well as on my phone, in parallel.

Omnara also displays realtime conversations between all Omnara clients. What I mean by syncing is syncing your conversation and code changes to a cloud sandbox, which is useful if you're using Omnara on your laptop and you close your computer (as explained in the original post). If you run your agents on a persistent cloud VM, then this is less of a value add.

I can voice chat with Happy coder.

We use https://docs.livekit.io/agents/ which runs the voice agent in the cloud (to enable the above use case, and a better experience when you're using your phone when it's off), whereas I believe happy runs a client-side voice agent.

Thanks for answering my questions! I see that Happy Coder is not far from Omnara. I hope Omnara can be not too far from E2E encryption. The lack of E2E encryption was why I didn't chose Omnara.

Two of the main feature's we're investing heavily into are remote sandboxes + syncing, and voice agent support, wouldn't work with E2EE.

Happy is an abandonedware unfortunately. It's a great app and dev can capitalize a lot from it but for some reason he hasn't been seen or heard in months since the last release.

There are attempts to create a fork maintained by other developers, but they're yet to be launched.
