Deep Dive: Switching from Sketch to Quant-UX
Trade-offs, installation & data architecture
What you trade away
It is a prototype-and-research workspace, not a full native vector design and reusable-library replacement for Sketch.
How to deploy Quant-UX
Use the hosted Quant-UX signup, or run its multi-container Docker Compose stack
What it takes to run
Self-hosting needs several containers plus MongoDB, SMTP, a JWT secret, WebSocket URL and reverse-proxy/TLS configuration
Where your data lives
Hosted projects in Quant-UX's service; self-hosted prototypes and tests in MongoDB with uploaded images in mapped data directories
Why fork Quant-UX instead of vibe-coding a Sketch clone?
The visible interface design loop is buildable, but a credible replacement needs more than the first screen. Sketch earns its keep through editor polish, assets, algorithms, so expect a weekend or multi-day build and a narrower personal scope.
