The PCB, not a plan
siliXon generates the board layout instead of stopping at a wiring diagram.
The Blueprint alternative that designs the board itself
Blueprint.io gives you a very nice plan: a shopping list of off-the-shelf modules with sourcing links, a wiring diagram, assembly steps and a 3D render of how it might look. You still order the parts, wire them together and build the thing yourself, and there is no custom PCB at the end of it. siliXon designs the board itself: real parts, a schematic, a placed and routed layout you can edit in 2D and 3D, and the files a fab needs to manufacture it.

Verdict
Choose siliXon when the custom circuit board is the hard part.
Choose Blueprint.io to plan a build around off-the-shelf modules.
siliXon todaysiliXon is in early beta and builds two- and four-layer, mostly digital boards. Review every design before fabrication.

So far creating my first project for 10 min - onboarding seems quite smooth
I like the self validation and how it explains everything too, makes it easier for me to quickly cross reference and learn on the go
Response is very meaningful, I like how it asks you questions to verify and gives you the options to choose the answers with the recommended on the one it thinks is a better option
Good so far. It is helpful and gives me advice
I have to say I love the UI and UX, the front end is really fun to interact with, with the little dynamic touches etc
Super helpful and easy to use
Really good actually better than Flux ai

What is the main difference?
Blueprint.io produces a build plan: parts, wiring, instructions and a render. siliXon produces the PCB and its fab files.
Does Blueprint.io make a PCB?
Its public FAQ does not describe PCB layout or fab files, and says manufacturing is not available yet.
Which fits a custom circuit board?
siliXon, when you need an editable PCB with real parts and a full fab package.
Can I use both?
Yes. Plan the wider build in Blueprint.io and design its custom board in siliXon.
