Synthetic demo board

WireHub

Capture the cable assemblies you build as one canonical definition, and get everything else derived from it: schematic, build sheet, BOM, continuity spec and drawing. Self-hosted, free software, deterministic output.

See it work

From a new design to a build sheet, about twenty seconds: the wizard wires what the catalog states unambiguously, the canvas lets you change any joint, and every document follows.

What you get

Every document is derived from the one definition, so they always agree.

Schematic laid out for you, with a legend and cross-section

Build sheet the bench flow, one stage per step

Continuity spec what must connect, what must stay isolated

Drawing sheet BOM, outline and title block on a framed sheet

Plus a BOM, formboard, wire labels, CSV and XLSX exports, and WireViz import and export.

What is in it

• A hierarchical wire model. A stock is a tree: cables hold pairs, coax and cores, which hold conductors, shields and insulation. Bonded screens, drains, pigtails and breakouts (moulds where some conductors pass through and others end) are modelled as they are built.
• A connector library. A connector is a physical body (DE-9 male, XLR3 female) composed with a pinout (RS-232, balanced audio). Reuse one body for many pinouts.
• PCBAs as black boxes with declared internal continuity, so a trace runs through a board without modelling its electronics.
• Derived, deterministic output. Nets and traces, a continuity spec, a BOM, a bench build sheet, an ELK-laid-out SVG schematic and an ANSI-A drawing sheet all come from the same JSON definition, byte for byte the same every time.
• An editor. A React canvas for the wiring, a parts library with 3D views, a new-cable wizard, versions, edit locks and an optional login.
• Modules. Domain vocabularies (video, audio, fieldbus …) and what only one shop needs (its ERP link, its numbering scheme, its own importers) plug in at build time through a small registry instead of living in the base.

Run it

You need Docker and one file — no clone, no .env:

mkdir wirehub && cd wirehub
curl -fsSLO https://raw.githubusercontent.com/formless63/wirehub/main/compose.yaml
docker compose up -d
docker compose logs wirehub        # the first-run setup code

Open http://localhost:5183/setup, enter the setup code and finish the short form; you land on a list of example designs to open. In a Docker UI (Portainer, Komodo, Dockhand …), paste compose.yaml as a stack, deploy, and read the code from the wirehub container's logs.

On first start a one-shot bootstrap service generates every secret the stack needs into a secrets volume and keeps it there. The few install choices — the public URL, ports, backups (COMPOSE_PROFILES=backup), your own PostgreSQL or S3 — go in an optional .env; .env.example explains each. Everything else — single sign-on, magic links, allowed emails, alerts, the git mirror, job settings — is set in the app under Settings and applies without a redeploy.

Config generator: https://formless63.github.io/wirehub/generator/ — pick your options and get a ready compose.yaml and .env. It runs entirely in your browser and sends nothing anywhere.

First-run setup lists the bundled domain modules whose signals, connectors and example cables you can add — PC & serial (RS-232, RS-485, USB), Networking (RJ45, T568A/B), Pro audio (XLR, TRS, RCA), AV / video and Automotive — all unticked unless the deployment suggests some. Nothing is required, and more can be enabled later from the command palette. The base itself stays generic: its starter catalog holds wire stocks, generic connectors (DE-9 by pin number, JST XH, terminal blocks), parts and a few neutral example cables.

The stack is the app, PostgreSQL 18 and Garage (S3-compatible storage for uploaded files), plus restic backups through Backrest as an optional profile. docs/self-hosting.md has the details.

Develop

From source (Node 24+, pnpm 10 — corepack enable):

git clone https://github.com/formless63/wirehub && cd wirehub
pnpm install
pnpm --filter studio dev        # open the printed URL

The hub opens on the generic starter catalog: a few example cables built from a small library of generic parts, every value cited to a public standard or marked as a synthetic example. The catalog is plain JSON under packages/catalog/data, and saves go straight back to it; domain modules enabled at setup install their packs into the gitignored data/packs/, so they never land in a commit to the base.

pnpm build                      # tsc --noEmit, strict, every package
pnpm test                       # vitest, each workspace in turn
pnpm --filter @wirehub/model test -- test/trace.test.ts
bash scripts/privacy-check.sh --tree

pnpm install also enables git hooks that keep home paths, secrets and personal emails out of commits (CONTRIBUTING.md).

• WireHub itself stays open. If you modify WireHub and run it for others — including over a network — you offer them the source of your modified WireHub, under the AGPL.
• Modules can use any licence. A module that talks to WireHub only through the module API (@wirehub/modules, the model and catalog types) and the catalog-pack formats may be MIT, proprietary, or anything else. You can build and distribute a WireHub image that includes it without the module becoming AGPL, and without publishing its source.
• @wirehub/modules is MIT, so module authors can depend on it freely.
• Catalog data is CC0-1.0. The starter catalog (packages/catalog/data) and the bundled modules' packs are dedicated to the public domain, so the facts in them can be reused anywhere. Other packs, and records in them, carry their own licence (docs/catalog-store.md).
• Third-party material keeps its own licence (NOTICE).

There are no per-file licence headers: LICENSE, MODULE-EXCEPTION.md and each package's license field are the record (SPDX: AGPL-3.0-only WITH AdditionRef-WireHub-Module-Exception-1.0, packages/modules: MIT; packages/catalog: AGPL-3.0-only AND CC0-1.0, the code and its data; bundled modules: MIT, their packs CC0-1.0).
