About
fumi is a Chrome extension + native messaging host that lets you run JavaScript in any web page and invoke scripts on your machine from it — all managed as plain files in your editor, under version control.
Think Tampermonkey, but your userscripts can shell out to anything on your box.
Key features:
- Files, not a UI. Actions and scripts live in ~/.config/fumi/ — edit with your editor, track with git.
- Any language for host scripts. fumi.run("foo.py", payload) — bash, Python, Go binary, whatever is executable.
- Small, auditable surface. The host exposes exactly two operations: list actions, run a script.
- Tampermonkey-style frontmatter. @match, @exclude — familiar and declarative.
- Zero state in the browser. The extension is a thin runner; the filesystem is the source of truth.
Requirements: macOS, Google Chrome with Developer mode enabled.
