Your chat. Your PC. Your rules.

Nookmatrix is a free Windows app that turns your PC into a private Matrix chat server. Your messages, your data, your control.

Coming soon Read the vision

Built on the open Matrix protocol. Powered by Tuwunel.

Goals

Three things we refuse to compromise on.

Privacy by default

Messages live on your computer, where they belong. No central server holds everything. Matrix end-to-end encryption across every conversation.

Simple enough for anyone

Install, create an account, chat. Five minutes, no IT skills. No port forwarding, no config files, no DNS knowledge required.

Data sovereignty

Your chats, files, and keys stay on your machine. You can back them up, move them, delete them. Nobody else needs the key.

Vision

A quiet corner of the Matrix.

A nook is a small, private, sheltered corner. That is the feeling nookmatrix is built around: a private messenger tucked into your own PC, for your family, your friends, or your team.

The software is free, open-source, and always will be. It turns a normal Windows PC into a Matrix chat server that works on your local network out of the box. No subscriptions, no accounts on our side, no telemetry.

The paid part is just infrastructure — a small bundle of connectivity services that make the server reachable from anywhere without asking you to configure a router. The moment you want to chat from your phone outside the house, it works. That's it.

Roadmap

What's next.

A rough order, not a schedule. We ship when it's solid.

  1. Now

    Windows MVP

    Installer, local server, admin panel, DM and rooms, files, full end-to-end encryption. The product works offline on a LAN.

  2. Next

    DDNS & Easy Invite

    A stable name.nookmatrix.com address for every server, plus QR-code invites that pre-configure the client app. Onboarding drops from an hour to two minutes.

  3. Then

    Tunnel & Push Relay

    Reachable from anywhere, even behind carrier-grade NAT. No port forwarding. Reliable mobile notifications, even when your PC sleeps. This is when nookmatrix Connect launches.

  4. Later

    nookmatrix Network

    Private federation for teams and organizations with multiple locations. Central dashboard, managed certificates, one-click server enrollment and revocation.

  5. Later

    Cloud backup & hosted version

    Encrypted backups for your chat history and keys. For users who want 24/7 availability without leaving their PC on, a hosted nookmatrix with one-click migration.

We're being honest about where we are.

The first release focuses on text, rooms, and files. No voice or video yet — that comes later. We'd rather ship something that actually works than a pile of half-features.
