Overview

Bridge browser JS and host-side scripts via Native Messaging.

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. Source code: https://github.com/tkuramot/fumi
