Browser-based interface design, components, libraries, prototypes, comments, and multiplayer, with a credible import-and-self-host story.
licenseMPL-2.0
runsyour machine or their cloud
installUse the hosted signup, or download the official Docker Compose file and run docker compose up -d
dataHosted files in Penpot Cloud; self-hosted data in Docker volumes for PostgreSQL and uploaded assets, with exports based on SVG/CSS/HTML/JSON and open standards
the catch vs SketchIt is browser-first rather than a native offline Mac editor, with a much smaller plugin ecosystem than Sketch.
setupSelf-hosting requires Docker Compose, DNS and reverse-proxy/TLS knowledge; hosted signup has no setup blocker

A useful free prototype-and-test workspace with collaboration and analytics; less capable for production-grade visual systems.
licenseGPL-3.0
runsyour machine or their cloud
installUse the hosted Quant-UX signup, or run its multi-container Docker Compose stack
dataHosted projects in Quant-UX's service; self-hosted prototypes and tests in MongoDB with uploaded images in mapped data directories
the catch vs SketchIt is a prototype-and-research workspace, not a full native vector design and reusable-library replacement for Sketch.
setupSelf-hosting needs several containers plus MongoDB, SMTP, a JWT secret, WebSocket URL and reverse-proxy/TLS configuration
