OpenJanela open core
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
Screens are easy to write. Getting an arched, coupled unit to cut, price and glaze correctly is not. That part is already done.
Shapes, arches, coupled units, mullions, grids, cut sizes and cross-sections drawn to scale.
Pricing, construction and machining rules live in tables. Change a product without changing code.
Batches, stations, barcode tracking, cut lists, glass orders and remakes.
Every company on its own database, with schema updates applied automatically.
REST services for orders, pricing, production, inventory, shipping, CRM and more.
Odoo 19, QuickBooks, EDI and glass-supplier feeds, saw and machining-centre interfaces.
Aids to hit the ground running
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.
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.
Every registration includes a hosted OpenJanela with demo products, so you can see what the code does before you change it.
