The Arc browser's vertical sidebar, vibe-coded for Chrome: Spaces, pinned tabs and one-click Arc import in a side panel.
ChromeSideBar is a Chrome extension that brings the Arc browser's vertical sidebar to Chrome. Its author, monehsieh of monemone-org, is refreshingly direct about how it got made: "So I vibe-coded this extension to bring that to Chrome."
The extension displays pinned sites, bookmarks and active tabs in a side panel that recreates the Arc sidebar experience — including Spaces for tab grouping, IDE-style tab history, drag-and-drop organization, and one-click import from Arc. It is open source under Apache-2.0, rated 4.6 stars on the Chrome Web Store (v1.0.326, updated July 2026), and the GitHub repo shows steady work with a commit two weeks before this write-up.
Browser extensions are a good stress test for AI-written code — they live inside a host's API surface, handle real user data, and ship to a store with review. ChromeSideBar clears all of that and is genuinely useful for the Arc-curious who won't leave Chrome. A clean example of vibe coding shipping production software.
