View, review and share - without opening KiCad.
View & annotate KiCad schematics and PCBs
From GitHub to browser in seconds.
Open .kicad_sch and .kicad_pcb files instantly on desktop, mobile, or even a car infotainment system - no KiCad installation, no setup.
Review as you go
Lightweight, ad-hoc documentation built in.
Write notes, review designs, or teach others using the integrated text editor. Insert sections of your schematic or PCB with quick graphical annotations. Export everything as PDF or HTML for instant sharing.
Branch & release switching made simple
No Git skills? No problem.
Jump between branches, releases, and tags with a tap. See what changed between revisions without ever touching a terminal - even from your phone.
View the full Bill of Materials - instantly
All parts, all fields, no exporting required.
See every component, parameter, and datasheet link directly from the KiCad project. Perfect for sourcing, pre-production checks, and design reviews.
Private Workspaces for teams
Share only what each person needs to see.
Invite unlimited workspace users, set fine-grained project permissions, and assign admin roles. Designed for startups, contractors, and distributed hardware teams working with confidential designs.
Share any design with a link
Quick reviews. Zero friction.
Send a secure link to any project or branch - works anywhere. No ZIP files, no file hunting, no lost context. Revoke access instantly with one click if needed.
Public profiles that you control
Showcase your work. Keep the rest private.
Highlight selected projects to collaborators, clients, or recruiters. Your profile is mobile-friendly - because people check it in meetings, not on workstations.
Bookmarks that actually help engineers
Your most important designs, always one tap away.
Star critical projects or teammate profiles for instant access. Ideal when jumping between multiple designs or following someone's latest updates.
// Secure by design
Read-only access
We view your files to render them - never write, push, or change anything in your repo.
Never stored on our servers
Your designs stream straight from GitHub to your browser. They're never uploaded to or kept on CADPreview infrastructure.
Only what's needed
You pick exactly which repositories to share, and we request the narrowest GitHub scope possible.
Revoke anytime
Disconnect from GitHub in one click - access ends immediately, no leftover tokens.
// No account needed

// Who it's for
Your design lives in a tool most of your team can't open.
Give everyone a link - and they're in, on any device, without installing anything.
Firmware
Check a pinout or GPIO on an unmerged branch - without waiting on hardware.
Supply chain
Pull a live BOM at any revision instead of last Thursday's export.
Programme managers
See the real project state from one URL - no review meeting required.
CTOs & IP owners
Full visibility across projects without anyone learning a new tool.
Hardware engineers
Browse your whole back-catalogue of designs in seconds.
// Why sign in
Public repos are free forever. An account is where the real work lives.
Private workspaces
Confidential designs stay locked down - shared only with the people you choose.
Your whole team
Invite engineers to your workspace, set per-project access and assign admins. Built for distributed hardware teams.
Share & showcase
Secure links to any branch, saved bookmarks, and a public profile you fully control.

What our users say
Made our lives so much easier
"This has honestly made our lives so much easier. Our firmware team can pull up any design revision in seconds, and the PCB viewer with annotations has seriously cut down our assembly time."
Giulio A
Co-Founder at Ambient WorksMakes everything so much smoother
"Can't imagine working without CAD Preview. Having all our KiCAD designs in one place makes the electronics development process so much smoother - whether that's internal reviews, supplier meetings, or sharing information across departments. The private workspaces keep our sensitive projects locked down, while still making it easy to share them when needed."
