If Blender helped you with your projects this year, we're asking you to help us back.
For the past year, you've had access to professional 3D software, completely free. No subscriptions, no licenses, no limits. Blender has been there for your projects, your learning, your art, your business.
Today, we're asking for $5.
That's it. If every active Blender user contributed $5 this month, Blender Foundation would meet its entire yearly funding goal for 2026.
