Free to build on. Pay only if you need us on the hook.

Building a commercial product on Nebutra costs nothing — no fee, no licence key, no registration, no copyleft. Paid tiers sell support, SLAs, indemnification, and trademark rights, never permission.

Pricing & licensing FAQ

Questions about license tiers, refunds, and commercial use rights.

Is Sailor a monthly SaaS subscription?+

No. This pricing is for Sailor source-code licenses: Independent is free, Startup is billed annually, and Enterprise is custom.

Do you offer refunds?+

Startup commercial licenses include a 14-day refund window for initial purchases. Enterprise terms are handled in the signed contract.

Can I use Sailor for client work?+

Yes. A commercial license lets your team ship closed-source client or internal products within the licensed scope; white-label rights require Enterprise approval.
