Software for the far edge.
Quad4 is an independent software collective. We build all sorts of software, from mesh networking tools and offline-first web apps to self-hosted infrastructure. Everything we ship keeps working when the internet does not.
Six orbits
Everything we ship is built to work without asking a server for permission.
Mesh networking
Apps and services for the Reticulum network. Messaging, browsing and file sync that keep working off the regular internet.
Offline-first web
Apps for dictation, transcription and translation that run entirely in your browser. No servers, no leaks.
Self-hosted infrastructure
Ops platforms, forges, firewalls and libraries you run yourself. If it phones home, we do not ship it.
Security tooling
Our own repository scanner, a web application firewall, kernel sandboxing libraries and crypto primitives. Defense is a product category here.
Privacy by default
No trackers, no analytics, no telemetry. Encryption and offline modes are the default and your data stays on your devices.
Verifiable supply chain
SHA-pinned actions, hardened runners, signed container images and frozen lockfiles with release-age rules. Every build is attestable.
Featured projects
Messaging, calls and NomadNet pages over the Reticulum network. End of life 1 January 2027.
The Reticulum network stack, written in Go.
A web browser for the Reticulum network, built on Reticulum-Go.
Offline text translation in the browser.
Monitoring, status pages and deployments on your own hardware.
Lightweight AI agent for the terminal.
Install Python packages from rngit remotes with pip, pipx, uv or poetry.
From the void, a forge
Canonical trees live on the network via rngit. Our own forge at git.quad4.io is coming back online soon, and GitHub mirrors carry issues, CI and releases.
