StipaCaller vs NOX Chat

StipaCaller is a small, invite-only messaging and calling app for closed groups — family, friends, anyone who wants their conversations to stay between the people who were invited. Every chat is end-to-end encrypted. Voice and video calls run over a self-hosted backend, not a third-party cloud. There are no ads, no algorithms, no public discovery, and no phone number required. Sign-in is by invite code only. New users join when someone already on the network invites them — there's no public sign-up form, and accounts can't be discovered by searching for a name or number. Designed for small networks where trust is direct and the surface area is intentionally small. Built for people who want a simple way to stay in touch without their conversations becoming someone else's training data. Features: • 1:1 and group chats with end-to-end encryption (libsodium) • Send and receive voice messages • Send and receive photos and videos • Voice and video calls over a self-hosted backend (1:1 only) • Invite-only — no public sign-up, no accounts findable by phone number • No ads, no telemetry, no third-party analytics • Username-based addressing — no phone number required
