Mirror a channel both ways, or import your whole server. Nobody has to move all at once.

Locked on your device before sending, even the sender and community name. It uses the open Concord protocol, so anyone can verify it.

Discord's IPO, ID scans, and 2025 data breach have people leaving. We compare the top Discord alternatives on encryption, privacy, and who can shut you down.

If you have used Discord, you already know the layout: communities, channels, threads, voice, and moderation. The difference is underneath. Every community is end-to-end encrypted, your account is a key instead of an email, and communities live on many relays at once, so no company can ban you or delete your server. Read the full comparison.

Yes. Armada is free and open source under the AGPL-3.0 license, with no ads and no paid tier.

There is no company account to ban. Community owners moderate their own spaces, but no one can delete your identity or take your community down across all of its relays.

No. Signing up generates a cryptographic key, and that key is your whole account, on Armada and across every other Nostr app. How to store your key.

There is no iOS app yet. The web app at armada.buzz works on iPhone, and native apps exist for Android, macOS, Linux, and Windows.

Armada is in open beta ahead of its v1.0 release. Communities, encrypted DMs, and voice and video calls all work today, with new releases landing almost daily. Expect occasional rough edges while it matures.
