Cody Chat

Cody Chat is an end-to-end encrypted messenger for people—and for organizations that need messaging infrastructure under their own control.

Host your own relay. Keep control.
Companies, clinics, schools, government teams, and security-conscious groups can run the open-source Cody Chat relay on a VPS, office PC, or internal network. Traffic stays on hardware you operate. Messages are end-to-end encrypted: the relay is designed to pass ciphertext, so even the server operator cannot read conversations.

Why organizations self-host:
- Data sovereignty — routing stays on your infrastructure, not a third-party chat SaaS
- Zero-knowledge style relay — E2E encryption; the server is not meant to hold plaintext
- Compliance-friendly — physical control of the relay supports GDPR and internal audit goals (you remain responsible for your own compliance)
- Private / LAN networks — run the relay on your network so chat can stay inside the facility
- Auditability — open source on GitHub; review the code or build the APK yourself

Self-hosted relay:

Also for individuals: private chat with no phone number, QR/NFC invites, channels, and optional voice/video calls. Use the default relay now, or self-host later.

What you can do:
- One-to-one chats and channels with E2E messaging, voice notes, video clips, files, and optional voice/video calls
- Add contacts via QR, NFC, invite link, or code—no SIM required
- Use the default relay, or deploy Windows/Linux self-host (QR join + tunnel options for wss://)
- Delivery indicators show when a message was received and when it was opened/played
- Calls use encrypted peer-to-peer media when possible; optional TURN in Settings for harder networks

Notes: A reachable relay (internet or LAN) is required. Camera, mic, and notifications are used only for related features. Orgs remain responsible for their own security review, hardening, and regulatory compliance.
