The Problem

You're paying rent on your own conversations

$8.75/user/month adds up fast. 50 people? $5,250/year. 250? $26,250.

Your messages live on someone else's servers. Their outage is your outage.

No white-labeling. Your team sees their brand, not yours.

No message provenance. No cryptographic proof who said what.

Voice requires third-party integrations. Extra cost, extra complexity.

Yak

Own it. Brand it. Run it forever.

One-time setup. Runs on Cloudflare Workers. Pennies per month in infrastructure.

Your server, your data, your uptime. Full control.

Full white-label. Your logo, your colors, your domain.

Every message is cryptographically signed with Ed25519. Provenance built in.

Walkie-talkie is a first-class feature. Push-to-talk, voice messages, real-time.

Everything You Need

Built for teams that take
communication seriously

Push-to-Talk

Walkie-talkie built into every channel. Hold to talk, release to send. Real-time voice with waveform visualization.

End-to-End Encryption

AES-256-GCM encryption with X25519 key exchange. Messages are encrypted on your device. The server never sees plaintext.

Cryptographic Provenance

Every message signed with Ed25519. Tamper-evident hash chains prove message integrity and ordering.

White Label Ready

Your logo. Your colors. Your domain. Deploy Yak as your own product. Your team never knows it's Yak.

Rich Messaging

Threads, reactions, mentions, file sharing, image previews, message editing and deletion. Everything you expect.

Role-Based Access

Owner, admin, member, guest. Invite-only teams. Channel permissions. Full audit trail of every action.

Edge-First Architecture

Runs on Cloudflare Workers and Durable Objects. Sub-50ms response times globally. No origin server required.

Multi-Device

Web, mobile, desktop. QR code device linking with per-device encryption keys. Use everywhere.

Device-Level Keys

Each device gets its own Ed25519 signing key and X25519 encryption key. Revoke a device without affecting others.

White Label

Deploy it as
your product

Yak was built from day one to be white-labeled. Swap the logo, change the colors, point your domain, and deploy. Your team, your clients, your community sees your brand. Not ours.

Custom branding

Logo, colors, fonts, favicon. All configurable.

Your domain

chat.yourcompany.com. Full CNAME support.

Invisible infrastructure

No "Powered by" badges. It's yours.

Multi-tenant ready

Run separate teams on one deployment.

Same platform. Different brands.

Security Architecture

Not just encrypted.
Provably secure.

Zero-Knowledge Server

Messages are encrypted on-device with AES-256-GCM before leaving your browser. The server stores ciphertext only. Even with full database access, messages are unreadable.

Your device sees:
"Parts are printing. ETA 2 hours."
Server sees:
a4f8e2c1...b7d9f3a6

Message Provenance

Every message includes an Ed25519 digital signature and a hash-chain link to the previous message. You can cryptographically verify who sent it, when, and that it hasn't been tampered with.

Signature Ed25519 per-device key
