Runebender Core
Rust library and intended command-line interface for font operations that should run without a desktop or browser editor.
Open the browser build with its bundled demo font, then use the docs below to understand how the native editor, ComfyUI front-end, headless Core path, and older Druid work fit together.
01 Headless core
runebender-core is the Rust and CLI-shaped path for non-UI font work.
02 Separate editors
Xilem and Comfy are different interfaces with separate docs, status, and workflows.
03 Room to grow
Druid remains history; future front-ends can join without flattening the map.
Project family
One name, several editor paths.
Runebender is not one finished application. Core is the headless path, Xilem is the native editor, Comfy is graph-hosted, and Druid is the earlier implementation. The site should make that structure clear before asking anyone to install or read a manual.
Runebender Xilem
Native desktop editor. This is where the current detailed manual, install notes, shortcuts, tracing workflow, and source map live.
Runebender Comfy
Graph-hosted editor work: ComfyUI custom nodes, Vue/WASM surfaces, browser experiments, FONT wires, and node-based font workflows.
Runebender Druid
The earlier Druid-based Runebender implementation. It anchors the project lineage but is not the current front-end direction.
More hosts later
New front-ends should get their own docs instead of inheriting Xilem-specific behavior by default.
Documentation structure
Shared concepts, separate manuals.
Common vocabulary, source formats, support, and troubleshooting stay in shared docs. Editor behavior belongs under the editor that actually implements it, which keeps the site honest while the project is still changing quickly.
Understand the family
Core, Xilem, Comfy, Druid, and future front-ends each have a defined role.
Use Xilem
Build the desktop editor, open UFO sources, draw glyphs, trace images, and use shortcuts.
Use Comfy
Follow the ComfyUI/Vue/WASM path for node-based font work and browser-hosted experiments.
Use Core
Follow the Rust crate and CLI path for scripted, non-UI font operations.
UFO extensions
Explain Runebender format conventions, including hyperbezier storage and fallbacks.
Choose a channel
Report issues to the right repository and keep alpha behavior tied to reproducible evidence.

Glossary, format notes, support, troubleshooting, and verification stay independent from any one editor interface.
Read format notesXilem
The detailed current manual, install path, shortcut reference, tracing notes, and source map are native-editor docs.
Open Xilem docsComfy and Core
The Comfy and Core pages are intentionally lighter today, but they define clear homes for graph workflows, headless CLI work, and shared library behavior as those docs mature.
Open Comfy docsAlpha warning
Use copies. Verify against source.
Runebender is active experimental software. Keep real font sources under version control, confirm behavior against the current repository, and treat these docs as a map rather than a compatibility guarantee.
