Verdict The best workspace around a KiCad editor: versions, browser review, sharing and AI access in one place, free to start.
- Who it is for
- KiCad users who want a home for their boards: individuals and open-hardware makers who share publicly, and teams that need private boards, roles and review without making everyone install CAD.
- Cost
- Free plan at $0 a month for individuals, side projects and open hardware. Team and Enterprise plans have custom pricing on request.
Strengths
- Schematic, PCB, 3D view and BOM open in any browser, with no CAD installed.
- Saved versions with visual comparison of what changed between them.
- Share publicly, by link only, or with a password; team plans add member roles and board-level access.
- Remote MCP server lets assistants such as Claude, ChatGPT and Cursor read schematics, nets, BOMs and files, and save new versions only with your explicit permission.
- A public library of more than 9,000 open-hardware boards, searchable by component.
- Keeps your KiCad project files, so you can download a version and continue in desktop KiCad.
Limits
- It is not a design editor: you still design in KiCad.
- KiCad has the most complete support; Altium sources are kept and converted for viewing only.
- It does not merge simultaneous CAD edits, and has no pull requests.
- Uploads do not always render fully.
- Cost
- Learning
- Library
- Complexity
- Fab output
- Portability
