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.
Stesura is in private beta. Until it is generally available, every use — including evaluation in your own environment — requires a written agreement with Innov-Ars.
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 to be decided during the beta; contact us to discuss terms for your team and deployment model.
We plan a free tier with 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). It is not available yet: no free licence is granted during the private beta. See pricing for what is included.
You may evaluate the full editor through the public demos and, under a written evaluation agreement, 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.
