## What it is
Drawpile is a free, open-source collaborative drawing program that lets multiple people draw, paint, sketch, and animate together on the same shared canvas in real time. It also works as a fast, lightweight offline drawing app and runs on Windows, macOS, Linux, Android, and in the browser.

## Use cases
- draw together with friends on a shared canvas
- collaborative sketching and painting sessions online
- host a multiplayer drawing session on a community server
- lightweight offline drawing app with layers and brushes
- collaborate on frame-by-frame animation with a timeline
- draw on a pressure-sensitive tablet across Windows, macOS, Linux, or Android
- sketch in the browser on an iPad without installing anything

## When to choose
- you want real-time multiplayer drawing on one canvas
- you need a free, cross-platform painting app with layers, blend modes, and 200+ brushes
- you want to animate with onion skins and timelines, alone or with others
- you need pressure-sensitive tablet support on all major platforms
- you want to export to OpenRaster or PSD to finish work in Krita or Photoshop

## When to avoid
- you need professional-grade photo editing or print production tools
- you require deep plugin ecosystems or scripting like Krita or Photoshop
- you need vector illustration rather than raster drawing
- you want a fully polished, corporate-supported product with guaranteed support
