Pencil2D vs Rive

Pencil2D is free, open-source software for creating hand-drawn 2D animations. It runs on Windows, macOS, Linux and, according to the homepage, FreeBSD. The project provides stable builds for Windows 7 or later, macOS 10.14 or later on Intel, and both 32-bit and 64-bit Linux. Artists can switch between raster and vector workflows for sketching, inking and painting. A timeline manages keyframes, while dockable tool and color windows accompany an unlimited canvas with a camera field. Onion skin displays drawings before and after the current keyframe, with controls for drawing count and transparency. Sound can be imported through a sound layer, although waveform display is still pending. Exports include MP4, WEBM, AVI, GIF, APNG and PNG image sequences. Video importing, text tools and shape tools are not implemented. Pencil2D is free for commercial use. Help is available through its forum, Discord, tutorials, FAQ and user manual.

Rive is a tool for designing 2D animations, motion graphics, and rigged characters, with an editor for building animated content. The editor is available as a desktop app, and command-line support is listed for macOS, Linux, and Windows. Rive content can run natively on mobile, desktop, web, consoles, TVs, and vehicles; integrations include Web, iOS, macOS, Android, Flutter, React, React Native, Unity, and Unreal. Export formats are RIV, REV, MP4, GIF, PNG sequence, and WebM. The Editor can be used free to explore, learn, and build.
