Flexible design

Pushing your limits means bending without breaking, and that takes a toolset that holds up. Kestrel covers the whole process, from canvas to code.

  • Precise vector editing

    Kestrel began life as a vector editor. Boolean operations, shorthand maths in every field and proper multi-border editing keep shape work quick and predictable.

  • Variable and OpenType fonts
  • A canvas without limits
  • Ready for design systems

Consistent design

Projects move fast and deadlines are real. Cut out the repeat work and ship quality without the scramble.

  • Reusable board templates

    Don't redraw the wheel. Turn any board — and everything on it — into a template, then reuse it across documents. Add board templates to a library and every document can reach them.

  • Responsive, reusable, synced components
  • Shared styles for text, layers and colour
  • Test fast with realistic prototypes IMPROVED

Design that grows with you

The way you work keeps changing. Kestrel keeps up — documents are versioned as you go, so a quick change, a new teammate or a whole new process never costs you the file.

What we love: how quickly Kestrel gets out of the way, whatever your level. Start from an empty canvas, or from one of the hundreds of templates for app mock-ups, social posts, planning boards and more.
