Quilter

Quilter is a physics-driven AI platform that automates printed circuit board (PCB) placement and routing. Using reinforcement learning, it converts a schematic into multiple fabrication-ready layout candidates in hours instead of weeks, validating each against physical constraints through Physics Rule Checks (impedance control, differential pairs, power nets, bypass capacitors, keepouts, and stackup rules). Quilter supports Altium, Cadence Allegro, Siemens Xpedition, KiCAD, and OrCAD formats and handles boards of roughly 100-1,000 components with 2,000-5,000 pins to route. It is delivered as a hosted web application (app.quilter.ai) with a startup program and a free tier; there is no public developer API, SDK, or CLI surface at this time.

Quilter is profiled on the APIs.io network. Tagged areas include Company, Ai Ml, PCB Design, EDA, and Electronics Design Automation.

Quilter’s developer surface includes documentation, support, engineering blog, changelog, pricing, and 8 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/quilter: open an issue to ask a question, or submit a pull request to add artifacts.
