A free, browser-based wireframe tool — no sign-up, no download, and nothing you sketch is uploaded. Rough out a screen before you build it using six ready-made elements: buttons, input fields, cards, a navbar, an image placeholder and a browser frame. Works on desktop, tablet and phone with a mouse, trackpad or stylus. Export the finished low-fidelity mockup as a PNG, an SVG or a re-editable JSON project.

Wireframe a screen before you design it
Low-fidelity wireframes are for settling structure and flow before anyone argues about colour. The templates panel carries six ready-made elements — Button, Input field, Card, Navbar, Image placeholder and Browser frame — and the toolbar adds 12 general tools (select, pencil, line, arrow, rectangle, rounded rectangle, ellipse, polygon, text, sticky note, image and eraser) for annotations and custom blocks. Everything stays vector while you edit, so SVG exports stay scalable and PNG exports render at 2x.
1
Frame the screen. Drop a Browser frame on the canvas to set the boundary you're designing inside.
2
Block out the layout. Add navbars, cards, inputs and buttons for each region of the page.
3
Tidy it up. Turn on the grid, then drag a placed element to snap it into alignment. Duplicate with Ctrl/Cmd+D to repeat rows.
4
Export or iterate. Save a PNG or SVG to drop into a doc, or a JSON project to keep refining later.
How this compares: unlike Figma or Balsamiq there's no account, no component library and no real-time multiplayer — this is a single-user, low-fidelity sketching canvas for the first pass, not a full design system. It loads instantly, needs no sign-up, and every wireframe stays on your own machine as a portable JSON file.

Wireframe tool FAQ
What can I wireframe with this tool?
This wireframe tool sketches low-fidelity screens for websites and apps. Drop in browser-frame chrome, buttons, input fields and layout blocks from the templates panel, then arrange them on a snap-to-grid canvas to rough out a page or flow. Every element stays a separate editable object, so a screen can be rearranged as often as the idea changes.
Is this a low-fidelity wireframe tool or a full UI design tool?
The wireframe tool here is deliberately low-fidelity rather than a full UI design tool. It is built for laying out structure, hierarchy and flow before you commit to visual design, with shapes, text and templates that stay quick to sketch and easy to rearrange. There is no component library, styling system or interactive prototyping, so a wireframe that needs those is best exported and taken into a dedicated design app.
Can I reuse the same wireframe elements across a mockup?
Yes — wireframe elements are meant to be reused across a mockup. Duplicate any element or group with Ctrl/Cmd+D, and use the alignment and distribution tools to keep buttons, inputs and blocks evenly spaced across a screen. Copy and paste works between screens on the same canvas too, so a nav bar drawn once can sit at the top of every page.
How do I share a finished wireframe?
Export it as a PNG or SVG image to drop into a doc or slide, or save the JSON project file so you or a teammate can reopen and keep editing the same wireframe later. PNG drops straight into a doc or slide, while SVG stays sharp at any size. Keep the JSON while the wireframe is still moving — it is the only export that reopens with each block still separate.
Are there keyboard shortcuts?
Yes — the wireframe tool has keyboard shortcuts for editing, view and tool switching. Ctrl/Cmd+Z undoes and Ctrl/Cmd+Shift+Z or Ctrl/Cmd+Y redoes (up to 50 steps), Ctrl/Cmd+D duplicates the selection, Ctrl/Cmd+C and Ctrl/Cmd+V copy and paste, and Delete or Backspace removes what's selected. Plus and minus zoom in and out, holding Space lets you pan the canvas, and Escape finishes a polygon. Single keys switch tools: V select, P pencil, L line, R rectangle, O ellipse, T text, A arrow.
What colour tools are included?
Pick a base colour and the harmony picker generates nine sets from it — shades, tints, tones, monochromatic, complementary, split-complementary, analogous, triadic and tetradic. You can also load a reference image and pull its dominant colours straight into the swatch tray. Clicking a swatch sets the active stroke or fill, whichever the colour switch is pointing at, and applies it to any block you have selected.
