Drawpile vs HEAVYPAINT

Drawpile is a drawing, painting, sketching and animation app for people working together on one canvas, with offline use also available. It runs on Windows, macOS, Linux, Android and the web; on iPhone and iPad, the browser version works, but there is no native iOS app. Its toolkit includes more than 200 built-in brushes, several brush engines, a brush editor and stroke stabilization. Layers and layer groups support blend modes, alpha preserve, clipping groups, masking and alpha lock. Animation tools include a timeline and onion skins. Canvases can be saved as OpenRaster or PSD, and images can be pasted from files or other programs. Users can join official community servers without arranging their own infrastructure, or operate a server themselves. External authentication can let users access potentially untrusted third-party servers without sharing their password with those servers. Drawpile says it does not transfer information to other networked systems unless a user or operator specifically requests it. The free plan costs nothing.

HEAVYPAINT is a digital painting app focused on raw, digital-impressionist work. Its listed tools include Color Jitter, Fan Fill, Lasso Fill, Rake, Line Blend, and Liquify, alongside shape design and customizable tools. The interface is minimalist, and a gallery helps users review and organize creations. The app is aimed at plein air painters, artists making quick color studies or concept sketches, figure and gesture artists, and people seeking a digital aesthetic. Brush customization, layers, and pressure sensitivity are supported. HEAVYPAINT is available on the web, iOS, Android, Windows, macOS, and Linux; the homepage links to its web app and mobile store versions, while Classic desktop downloads are available for Windows, macOS, and Linux. HEAVYPAINT 3+ accounts work across devices. A free plan is listed, along with Gallery Sync Monthly at $2.99 a month, Unlock Full Version at $9.99 as a one-time purchase, and Gallery Sync Yearly at $19.99 a year. Classic remains available but receives no new features or bug fixes. Exports are pixel-based, and pixel dimensions determine print resolution.
