Free Browser-Based Tools
Standalone utilities built to pair with the Visualization Builder — each one runs entirely in your browser, with no account, no upload, and no server round-trip. Use them on their own, or generate something here and copy it straight into a Builder window.
Web Drawing Tool
A browser-based CAD editor for DXF drawings — import, draw, snap, and edit lines/arcs/ circles, then export DXF/SVG/PNG or send the drawing straight into a Builder window.
Design Match
Paste a screenshot of a look you like and extract its color palette, then preview five widget types (card, button, badge, banner, progress bar) restyled to match it instantly.
CSS Slot Machine
Spin for a random color/shape/text combo and get a complete, ready-to-run JavaScript widget — useful whenever you want a decent starting style without picking colors by hand.
Every tool above is self-contained and works without the Builder open — but each one is specifically built to hand its output to it. CSS Slot Machine and Design Match both produce a "+ JavaScript Window" snippet you paste directly onto the canvas; Web Drawing Tool can send a finished drawing into the Builder as a window in one click. None of them require an account or send your data to a server — processing happens locally, in the same browser tab you're using right now.
