Open-source Adobe After Effects alternatives

TiXL, formerly Tooll3, is open-source software for creating real-time motion graphics. It sits between real-time rendering, node-graph procedural generation and linear keyframe animation, so artists get both generative flexibility and precise timeline control.

That combination lets artists build audio-reactive visuals for VJ performances, explore parameters through specialized interfaces, or blend keyframe animation with automation. Technical artists can go deeper and write fragment or compute shaders, or feed in input from MIDI controllers, sensors and sources such as OSC or Spout. The project is a .NET application built on DirectX 11 with an ImGui-based interface.

TiXL is licensed under MIT and runs on your own computer, with a website offering downloads and documentation. It is aimed at motion designers, VJs and creative coders who want a free alternative to commercial real-time graphics tools.

Synfig Studio is a free and open-source 2D animation program built for creating film-quality animation from vector and bitmap artwork. Instead of drawing every frame by hand, you set key positions and the software works out the frames between them, which lets small teams produce higher-quality animation with fewer resources.

It is available for Windows, Linux and macOS, and the codebase is C++ using the gtkmm toolkit, licensed under GPL-3.0. The official repository contains the Synfig Studio source, installation instructions for each platform's packages and notes on building and installing from source. Project topics highlight vector graphics and 2D animation.

The project is supported by code contributors and by individual and organizational financial contributors who sustain the community, and static analysis is run with PVS-Studio. The latest release listed is v1.5.5. Synfig suits independent animators, students and small studios who want a free tool for cutout, vector-based and bitmap-mixed 2D work.
