flapart · first edition

A little painting room.
A lot of possibilities.

Start with a blank canvas. Brush, erase, fill, shape, and build up layers. Everything you make can leave with you.

In your browser

No installation or account needed to draw. PNG, JPEG and WebP image exports; editable .flapart files keep your layers. Recovery is stored in this browser. Download a project file for a real backup.

Your private shelf

A Flaptown account lets you save projects privately. Publish a separate image to your profile's image library, or post it in Town Square. Your editable project stays private.

The native edition builds on Krita's painting engine, with a simpler Flapart Studio entrance and the deeper tools still available. This is a separate native project; the browser editor does not open Krita .kra files.

Flapart Studio for Linux

A full native painting workspace with Krita’s tools, guided Flapart controls, and separate settings. The installer downloads the verified official engine and verified TLS and Python updates; after installation, drawing works offline.

download Linux installer →

Linux x86_64 · glibc 2.35+ · Python 3.9 or later · X11 or XWayland. About 399 MiB to install. Export PNG, then open it in the browser editor to share with your Flaptown account.

Flapart Studio for Krita

A GPL plugin with guided canvas creation, editable save, PNG export, focus controls, and a browser handoff for sharing. Requires an existing Krita installation with Python plugins.

download plugin →

Plugin, not a standalone installer. Native drawing, editable save, export, and menu controls tested on Linux, Windows, and Intel and Apple Silicon Macs. Physical tablet coverage varies by device.

Native source edition

Build recipes and upstream identity are included with source. Native installers will appear here when packaged and qualified for their operating systems.

A compiled source fork remains under qualification. Windows and macOS installers are not released.

Install on Linux
  1. Download and extract the Linux installer ZIP.
  2. Open a terminal in the extracted Flapart-Studio-Installer folder and run sh install.sh.
  3. Wait for the verified runtime download and installation. No administrator password is needed.
  4. Open Flapart Studio from your applications menu. Your existing Krita setup is kept separate.

The included README explains system requirements, upgrades and removal. Python update source and build recipe are also available. Keep editable .kra files for native projects; export PNG to bring an image into the browser editor.

Install the Studio plugin
  1. Download and unzip the plugin archive.
  2. Read its README for the supported Krita version and installation steps.
  3. Copy the included pykrita and actions folders into Krita's resource folder, enable Flapart Studio in Python Plugin Manager, and restart Krita.
  4. Open Tools → Scripts → Flapart Studio.

Existing Krita settings and documents stay yours. The plugin's focus controls can be reversed. Save your editable work before exporting or closing.

What this edition supports

Layers, opacity and blend modes; pressure-sensitive strokes; drawing and shape tools; selections and movement; undo and redo; image import and export; local recovery; private cloud saves; explicit image sharing.

Browser projects are bounded to 4096 pixels per side, 32 layers and a total pixel budget. Cloud saves accept up to 16 MiB per project; larger projects can still be saved to your device. Pen pressure depends on your browser and device.

The browser editor is an original implementation informed by Krita research. It is not a port of Krita's full engine, and does not promise its animation, color-management, brush-engine or file-format coverage.

Questions and improvements belong in the Flapsoft community workshop. Source packages include tests and known limitations.
