Open-source software

Last updated: November 7, 2026

Quotara is built with open-source software, and we are grateful to the people who write it. This page lists the components that run in your browser under licences that ask us to tell you about them, with their licences and their source code.

3D model reading

Quotara makes use of facilities provided by the Open CASCADE Technology software.

When you add a STEP or IGES file to a quote, your browser measures it using the two components below. They are loaded as separate files, only when a 3D file is measured, and are used exactly as published, without changes.

occt-import-js 0.0.23By Viktor Kovács. Reads STEP, IGES and BREP files in the browser.

The files Quotara serves are at /occt/0.0.23/. You may use, copy, study, change and replace these components as their licences allow, and nothing in our Terms of Service limits those rights. If you would like a copy of their source code from us, email hello@getquotara.ca and we will send it at no charge. This offer is open for three years from the last time we served these files.

STL files are read by Quotara's own code. Measuring happens on your computer, and the 3D file is not sent to our AI provider.

Everything else

Quotara also uses open-source packages under permissive licences, such as the MIT licence, including Next.js, React, React PDF and the Supabase client libraries. Their licences are kept with each package's code.
