The code's all on Github: https://github.com/Cryptodog/cryptodog. No signed extensions or apps yet, but you can clone and run locally for testing purposes, or use the hosted client linked there.

So far, we've been focusing on refactoring, fixing surface bugs, and making the UI more attractive and intuitive -- none of the underlying cryptography has been touched. It also performs slightly faster than stock Cryptocat. Since Nadim took down his XMPP server, we've had to create our own, but the backend is identical to his setup.

Of course, Cryptodog is by no means the best solution for E2E chat, just as Cryptocat wasn't. The best we can hope to achieve without a complete codebase overhaul is a reasonable level of security (https://leastauthority.com/static/publications/LeastAuthorit...). However, it's still a fairly usable app that can afford casual users protection against basic threats, like corporate data mining.
