Stesura is proprietary software developed and owned by Innov-Ars. It is not open source. This page summarises how it may be used; the licence agreement you sign governs in full.
Embedding Stesura in a product — internal or customer-facing — requires a commercial licence from Innov-Ars. The licence covers the editor packages you use, updates during your licence term, and support as agreed. Pricing is being finalised during the beta; contact us to discuss terms for your team and deployment model.
The free tier provides the core editing experience — rich text, tables, DOCX import and export, track changes, comments, and collaboration — without the pagination packages (paginated layout, sections with headers and footers, and PDF export). See pricing for what is included.
You may evaluate the full editor through the public demos and during a trial period in your own environment. Evaluation use must not be exposed to production end users.

Stesura builds on open-source software, most notably ProseMirror (MIT). Its licence and attributions are included in the distributed packages.
