Why we exist

Appliances that respect people and the planet

Open hardware

Complete CAD, schematics, and bills of materials published under open licenses so anyone can reproduce, repair, or remix the designs.

Open source firmware

Firmware and interfaces built with accessible toolchains, ready for translation, customization, and security auditing.

Environmental stewardship

Circular design principles, modular components, and efficient power profiles to minimize lifecycle impact.

In development

Flagship prototypes

Every prototype includes comprehensive build guides, validated parts lists, and community-led testing reports.

How we work

The Open Appliance Blueprint

01

Research needs

Field interviews and lifecycle assessments identify the highest impact appliances for decarbonized homes.

02

Co-design and prototyping

Community sprints and distributed fabrication labs iterate on designs with rapid feedback loops.

03

Open release

We publish CAD, firmware, documentation, and life-cycle data under permissive licenses for maximum reuse.

04

Local manufacturing

Fabrication partners and makerspaces receive tooling packs and training to produce validated builds locally.

Resources

Everything we build is yours to remix

Documentation portal

Step-by-step build guides, maintenance manuals, and compliance resources translated into multiple languages.

Browse docs

Open BOM library

A searchable database of vetted components with sustainability scores, supplier footprints, and lifecycle cost estimates.

Search components

Knowledge exchange

Monthly forums, skillshares, and repair clinics to keep appliances in service longer and support local fabricators.

Join the forum

Impact dashboard

Transparent reporting on embodied carbon, service lifetime, repairability, and social impact metrics across projects.
