Estimia for developers
Estimia builds tools for the window industry in Spain — and you can put them on your own site. Our widgets embed with a single copy-paste snippet and are hosted and kept current by us: all JavaScript, CSS and data load from estimia.es, so they add no weight to your site. Terms are per widget — some are free, some will be paid — and each widget's page states its own.
Calculators
Interactive tools that answer the money questions your visitors actually have — and keep them on your page while doing it.
