Unsigned builds for now: Windows/macOS may show an "unknown publisher" prompt — choose "More info → Run anyway" (Windows) or right-click → Open (macOS). Linux: double-click the .deb to install; FORMA appears in your app menu. Closing FORMA's window shuts it down completely — nothing runs in the background.
☕ Pay what you feel — support FORMA on Ko-fiFORMA is free; if it's useful to you, a coffee keeps it moving. Built by 3D3D (Nova Scotia, Canada) on great open source — SketchForge, text-to-cad, build123d/OCCT, Trellis — credit where credit is due. Feedback welcome on GitHub.
