## Editorial review

SimpleX uses pairwise per-contact identifiers — there is no global username, phone number, or even random ID that links to you. Self-hostable relay servers, end-to-end encrypted, supports voice/video. Open-source and currently the strongest anonymity story in mainstream messaging.
