Push-to-Talk
Instant voice channels — crew, dock, and boat — with no latency lag and no cloud account required to activate or maintain them.
Software · free
Your crew, one voice
channel. No cloud.
Used by the 3D3D crew on remote build jobs and field work across New Brunswick. When we deploy Yak for your team, you host it on your own server — no external service touches your communication.
Yak is a private team communication tool: push-to-talk voice, encrypted chat, and file handoff with tamper-evident message stamps. No cloud accounts required — it runs self-hosted on your own server, on your own domain, with no external service touching your data.

Open Yak What do you get with Yak?
A named system of 4 components — not a list of features, a description of what the software actually does.
Encrypted Messaging
Text and file handoff with delivery confirmation and tamper-evident stamps. Each message hashed at send time; the chain is auditable.
Message Audit Trail
Every message receives a hash that can be verified later. Nothing was deleted or altered silently. The record stands up to dispute.
Self-Hosted Mode
Run Yak on your own server, your own domain. No external service handles your crew's communications, stores your logs, or can be subpoenaed for your data.
Who built this, and why does it work?
Used by the 3D3D crew across remote build jobs and field work in New Brunswick. No cloud accounts, no external service — the server runs on our own hardware.

How much does it cost to build something like Yak?
Three fixed tiers for scoped work. All include full source handover, your hosting, your keys — no ongoing seat licence required.
Starter build
$1,500
One-time fixed-scope deliverable. Best for single-feature tools, internal utilities, and clearly defined automation.
Mid-scope build
$2,500
Discovery, design, build, and handover. Best for client-facing apps and systems that need a defined user experience.
Full custom build
$5,000
Complete scope, full source, and production deployment. Best for commercial apps and anything shipping to paying users.
All prices CAD. We scope before we quote — describe the problem at info@3d3d.ca and we will respond within 24 hours.
Questions about Yak.
Does Yak require a cloud account or subscription?
No. Yak is self-hosted. You run it on your own server and your crew connects directly. No external service handles your communication, stores your logs, or retains your data.
Is the voice channel encrypted?
Yes. Voice and chat are encrypted in transit. Message hashes are stamped at send time; the chain can be verified later to confirm nothing was altered or deleted.
Can Yak be adapted for a commercial operations team?
Yes. The self-hosted model makes it suitable for teams where communications must stay internal — construction sites, marine operations, field service crews. Email info@3d3d.ca.
What hardware does Yak's server component require?
Any Linux VPS or on-premise server with at least 1 GB RAM. Client apps run on iOS and Android. The server component is a single binary with no external dependencies.
Owned software
Want one of these for your business?
Describe the problem. We design it, build it, and hand over the keys. No seat licences, no lock-in — you own what we build.
