Runebender is a cross-platform, free and open-source font editor built on the Linebender ecosystem of Rust crates. It runs on Linux and macOS, with Windows support in development.

It is designed to be an extensible and flexible base to build custom tools and workflows on top of, and uses the UFO and Designspace font source formats by default. It also supports importing Glyphs, Glyphs Package, and single-master Babelfont sources.

Included is a ComfyUI-like node editor for non-destructive workflows and local AI, with built-in support for DesignBot, a Rust DrawBot alternative built on the Linebender ecosystem.
