No installs. Works in any modern browser.

Everything in one place

A complete design tool, not a whiteboard.

From the first wireframe to the final hand-off, your whole workflow lives in Vellum.

Real-time multiplayer

Everyone edits the same file at once. See live cursors, selections and changes as they happen, with no merge conflicts.

Vector tools

Pen, shapes, boolean operations and precise bezier editing for icons, illustrations and pixel-perfect UI.

Auto layout

Frames that grow, shrink and wrap with their content. Padding, gaps and alignment behave like real CSS.

Components

Build once, reuse everywhere. Update the main component and every instance follows, with overrides preserved.

Prototyping

Wire screens together with clicks, hovers and smart transitions, then present a clickable flow in one tap.

Comments

Pin feedback right on the canvas, reply in threads and resolve when it’s done. Reviews stay next to the work.

Version history

Every change is saved automatically. Name milestones, compare past versions and restore any point in time.

Dev inspect & export

Developers get exact measurements, CSS and assets. Export PNG, SVG or PDF at any scale.

Multiplayer by default

One file. The whole team. Zero “final_v7”.

Share a link and your teammates are in. Designers, developers and product managers work in the same file, see each other’s cursors, and leave comments exactly where they matter.

  • Live cursors and selections for every collaborator
  • Share by email or link, with view or edit access
  • Teams and projects keep work organized
  • Export and import files in the open .vellum format
