Open core: don’t reinvent the wheel — build your fenestration software on ours.

OpenJanela open core

Don’t reinvent the wheel. Start your fenestration software from ours.

Building a window and door ERP, a dealer portal, a configurator or an AI tool for the industry? Start from the OpenJanela source code — the geometry, rules, pricing and production engine already running window and door plants — and spend your time on what makes you different.

Window and door software since 1987. Open source since 2011.

What you don’t have to build

Years of window and door know-how, ready on day one

Screens are easy to write. Getting an arched, coupled unit to cut, price and glaze correctly is not. That part is already done.

Window and door geometry

Shapes, arches, coupled units, mullions, grids, cut sizes and cross-sections drawn to scale.

Rules as data

Pricing, construction and machining rules live in tables. Change a product without changing code.

Production

Batches, stations, barcode tracking, cut lists, glass orders and remakes.

Multi-company from the start

Every company on its own database, with schema updates applied automatically.

Open APIs

REST services for orders, pricing, production, inventory, shipping, CRM and more.

Proven connections

Odoo 19, QuickBooks, EDI and glass-supplier feeds, saw and machining-centre interfaces.

Aids to hit the ground running

A map, not a maze

The source comes with the notes our own team works from, written so that a new developer — or an AI coding agent — can find the right place in minutes instead of weeks.

Ready for AI coding tools

OpenJanela is developed with AI coding agents every day. The same notes they use come with the source, so your own AI tools can find their way around from the first prompt.

A working system to test against

Every registration includes a hosted OpenJanela with demo products, so you can see what the code does before you change it.

Teams building with AI

AI can write screens in an afternoon. It cannot write decades of fenestration geometry. Start from ours.

FAQ

Questions developers ask

Community includes the core source: order entry, the configurator, the web configurator and single-order production. Enterprise adds the source of each module you buy. The hosted Base edition does not include source code.

Java 8 on WildFly with MySQL, a REST API, an Angular web configurator and a desktop client. Each company runs on its own database.

Registering and the Community edition are free. Enterprise modules are $1,000 each and come with their source. See the products page for all editions.

No. Most companies run OpenJanela as it is and change products, prices and rules from the screens. The source is there for when you want to go further.

Yes. We offer setup, training, catalog build-out and custom modules as a paid service. Contact us.
