FAQ
Common questions
What's the license for fluera_canvas?
MIT — the standard permissive license. Use it in personal, open-source or commercial products. No royalties, no change-date clauses, no attribution requirements beyond the MIT notice.
Do I need Pro to ship a commercial app?
No. The MIT core (fluera_canvas) is enough for most drawing apps. Pro is for teams that want the advanced modules — collaboration, AI, PDF annotation, the full brush set, encrypted storage — without building them themselves.
How is Pro priced?
Per product, per seat, or per company depending on scale. We're onboarding the first design partners — pricing is negotiated directly so we can match your stage. Email us with a sentence on what you're building.
Do you offer discounts for startups and researchers?
Yes. Pre-seed and seed startups, academic researchers, and accessibility-focused projects get significant discounts on Pro. Just ask.
Can I build a drawing app that competes with Fluera?
Yes. MIT puts no restrictions on what you build. Pro follows the same spirit — a standard commercial license with no field-of-use limits.
Is there a trial for Pro?
We give design partners a time-boxed trial license. Reach out — it's a short conversation.
