- Lopaka vs Penpot: Penpot is open-source and focuses on web UI/UX, not embedded display code export.
- Lopaka vs Excalidraw: Excalidraw provides hand-drawn style diagrams, not structured graphics for microcontrollers.
- Lopaka vs Webflow: Webflow builds responsive websites, not low-resolution embedded screens.
Lopaka FAQ
What happens to my projects if I cancel or downgrade?+
Existing projects stay accessible and editable; you just lose the ability to create new screens beyond your current plan limits.
Are projects public on the free plan?+
Yes, Basic and Hobby projects are visible in the public Gallery; they can be forked but not edited by others.
Can I export the generated code?+
On Hobby and Plus you can download the drawing code as a .txt file, or export the screen as PNG or BMP.
How do I add my own fonts?+
Upload a .ttf, .bdf or .h file; Lopaka converts it to the appropriate GFX header for your target library.
Is there a way to share a private project?+
Private projects are only visible to you; you can temporarily make them public to share a link, or use the Teams plan for collaboration.
What storage limits apply to assets?+
Basic allows 5 assets, Hobby 50, and Plus unlimited assets up to 1 GB total storage per account.
