Hey everyone, two of us have been working on a privacy-focused Discord alternative for some time and we’re opening it up for early testing to see how it performs and to get real feedback.

Kloak is privacy-first by design. There are no emails and no passwords. When you join, you’re given a secret key, and that key is your account. There is no recovery mechanism and no central identity tied to you. If the key is lost, the account is gone. This is intentional and meant to reduce stored user data and avoid creating identity honeypots.

Most of the core features are already in place. You can create servers, channels, roles, and permissions, upload files and custom emojis, etc.

We’re still early, and the main goal right now is to validate the model, catch UX issues, and stress the system a bit before going further. We’re especially interested in thoughts around the key-based account approach and any privacy or security trade-offs we may be overlooking.

If you’re curious or want to poke at it, it takes only a few seconds to join and doesn’t require any personal information. You can join Kloak at https://kloak.app/

Feel free to join our official server too through https://kloak.app/invite/PV3FEB8N
