Available for macOS & Windows

Illustration by Marius Bota

Serious about the craft of painting? So are we.

No subscriptions. And no generative AI, ever. We’re a small, independent team who loves painting and building great tools.

Value-Locking Color Picker

Click the lock icon above the color picker to adjust hue and saturation while maintaining value.

Then use Y to toggle greyscale view.

Unique Color Dynamics

Brush Jitter that mimics partially mixed paint, for painterly strokes without the lag of a mixer brush.

Multi-Layer Liquify

Liquify multiple layers anywhere in your file without merging!

All Flatbrush adjustments (Curves, Levels, HSB) support multi-layer editing... and so does our transform tool.

Pinned Brush Settings

Pin frequently used brush settings to your sidebar. Love color variation? Make sure it's always available.

Quick Layer Select

Right Click to quickly select layers under the cursor. No more digging around in the layers panel!

We’ve got the basics, too...

Import your PSD files and brushes. And if Flatbrush isn't for you... eject right back to PSD.

Apply for early access

Flatbrush is free while in alpha, and we're looking for more illustrators, concept artists, and visual development artists to join the white glove test group.

You'll have direct access to the development team, and they want your feedback! If you’ve ever wanted more of a say in how your painting tool works, now is the time to sign up.

Available for Windows & macOS

ABOUT US

Flatbrush is built by Ryan and Jamie! We have more than a decade of experience building creative tools for professionals. Giant file sizes, we gotchu!

Ryan is a lifetime hobbyist painter and is married to a professional illustrator, Jessica! She was our first Flatbrush user and she loves ordering us to build whatever features she wants.

We plan to keep Flatbrush indie forever, so we can prioritize the quality of our app instead of being beholden to shareholders. And you'll never have to worry about generative AI features being added to Flatbrush. In this household we barf on AI art! BARF!! Thanks for giving our app a try! We've poured a lot of love into it.
