When you need a 5-minute sketch

Product discussions die when the only options are a heavy design file or a wall of prose. A crude wireframe—boxes for layout, arrows for flow, a splash of fill for hierarchy—often unblocks the room faster than another paragraph in chat.

You want something that opens in the browser, works offline once loaded, and exports a PNG you can drop into Slack, a ticket, or a slide. That is the job of a client-side paint canvas, not a full design system.

What Waryway Paint is

Waryway Paint (https://waryway.com/paint/) is an HTML5 canvas drawing app served from the Waryway suite. It runs in the browser: pencil, eraser, shapes, flood-fill, text, select/cut/copy, undo/redo, open image, paste from clipboard, and save PNG. No account is required to sketch.

Not the same as Retronium. Paint is a solo (or local) canvas for quick markup. Retronium is a separate real-time peer product. For wireframes and callouts, start at /paint/.

Tools that matter for mockups

ToolShortcutMockup use
PencilPFreehand arrows, underlines, rough UI chrome
EraserEClean edges without clearing the whole board
Flood fillBSolid regions for headers, buttons, status chips
LineLDividers, flow connectors
Rect / filled rectR / Shift+RCards, panels, placeholders
Oval / filled ovalO / Shift+OAvatars, badges, soft shapes
TextTLabels, step numbers, callout copy
Select + cut/copySMove a block without redrawing
Undo / redoCtrl+Z / Ctrl+YExplore layout safely

Foreground and background colors control stroke vs fill. Stroke size is a range control (1–64). Use Help in the toolbar for the full shortcut list.

Quick mockup workflow

  1. Open Paint. Visit waryway.com/paint/ (or dismiss the empty-state card with “Got it” and start drawing).
  2. Block the layout first. Use filled rectangles for major regions (nav, main, side panel). Keep gaps consistent so the eye reads structure.
  3. Add structure lines. Outline rects and lines for tables, form fields, or mobile chrome. Prefer geometry tools over freehand for UI frames.
  4. Label with text. Short nouns only (“Search”, “Primary CTA”, “Error toast”). Avoid writing full specs on the canvas.
  5. Call out intent. Pencil or line arrows + one-word notes beat dense paragraphs. Flood-fill a highlight color on the element under discussion.
  6. Export PNG. Ctrl+S or Save PNG, then attach the file to the ticket or chat thread.

Scope tip. Paint is for clarity, not pixel-perfect design systems. If you need multiplayer whiteboarding with peers, look at suite collab products separately—don’t stretch a solo canvas into a meeting OS.
