🔐
End-to-End Encrypted
Messages travel directly between devices over WireGuard tunnels. No server can read your conversations.
💨
Ephemeral Messages
Messages exist only in transit. Nothing is stored on any server or device. When the chat ends, it's gone.
🕸️
Mesh Network
Connect directly to other devices on your private network. Works anywhere your WireGuard tunnel reaches.
📞
Call-Style Chat
Request a secure channel, wait for acceptance, then chat. Like a phone call, but with text.
🛡️
Spyder uses WireGuard® for transport encryption (ChaCha20-Poly1305) and Curve25519 for key exchange. Your messages never touch our servers.
