System · the mesh, it wires

Nexus

The layer it all runs on.

Nexus is the self-hosted platform that builds, wires and runs the systems and their stores on your own infrastructure, in the EU. Every release proves itself before it goes live, and anything with real-world impact needs a permission only a person can grant. It is the ground the product stands on, not a feature of it.

The infrastructure

How it flows

Systems + stores
cortex · lens · atlas · …
Nexus mesh
Self-hosted · EU · wired
  • Wires every system and store together over a private mesh.
  • Self-hosted: your data never leaves your infrastructure.
  • Automatic TLS, zero-downtime deploys, and a person's permission for anything with real-world impact.

How it fits

Runs and connects Cortex, Lens, Atlas, Thalamus, Larynx, Pharynx and the stores.

Under the hood

Self-hosted in the EU. Every release proven first.

Nexus is our own deployment platform: it builds every system from source, puts automatic TLS in front of it and runs the whole fleet in the EU. Every release proves itself before it goes live, and anything with real-world impact needs a permission only a person can grant.

The console · shown with demo data

The nexus canvas with demo data: apps as nodes wired to a public router, groups as outlined hulls, and a deploy soaking in the live queue

Apps are nodes on a canvas, grouped by what belongs together, and the queue at the bottom is a release waiting for its cutover. The same fleet, phone-sized, on the right.

Rollback
the old release stays

A new release builds in isolation, must pass its health probe, then runs dark for a soak window while production traffic stays on the old one. Only a release that stays healthy is cut over; one that fails never replaces what is live. Stateful apps and stores deploy stop-then-start with automatic rollback.

The rest of the constellation

This is one part of a system built to keep one promise: every answer is grounded and permission-aware, or it doesn’t come at all.
