Lumno

A lighter entry point for browser power users

A browser command bar for tab search, bookmark search, and site search

Lumno is an open-source browser command bar that opens focus search from any page. It puts tab search, bookmark search, history search, frequently visited pages, and site search in one lightweight overlay for Chrome, Edge, and Dia, including Arc migration workflows.

Core Features

Search browser context in one place

Find open tabs, bookmarks, history, and frequently visited pages from one input instead of jumping between the address bar, bookmark manager, and browser side panels.

Press Tab for site search

Lumno includes common site engines. Type a site keyword, press Tab, and send the query into the right website for docs, communities, repositories, or search engines.

Minimalist new tab

The new tab keeps bookmarks and useful page cards close without pulling attention into a feed. Opening a new window still starts with search, visit, or switch.

Arc migration friendly

If you are moving from Arc to Dia, Chrome, or Edge, Lumno preserves the high-frequency command bar workflow without asking you to replace the whole browser.

Where Lumno fits

  • Research recovery: use focus search to bring back context from bookmarks, history, and open tabs.
  • Work switching: jump between writing, code, docs, and search result pages with less browser friction.
  • Site search: send precise queries to GitHub, docs, communities, or search engines.
  • Arc migration: keep a familiar command bar rhythm inside Dia or Chrome.

People moving from Arc

Keep a familiar browser command bar, site search, and tab-switching workflow inside Dia, Chrome, or Edge.

Frequently Asked Questions

Is Lumno an Arc browser alternative?

Lumno is not a full browser and is not affiliated with Arc. It focuses on the Arc-style command bar search experience: quickly finding tabs, bookmarks, history, and site content from any page while using Dia or Chrome.

Which browsers does Lumno support?

Lumno is built for Chrome, Edge, Dia, and other Chromium-based browsers. After installing it, you can open focus search with an extension shortcut and use the minimalist new tab for common destinations.

How is Lumno different from regular tab search?

Regular browser tab search usually searches only open tabs. Lumno combines tabs, bookmarks, history, frequently visited pages, and site search in one command bar, so the search surface is broader and the path is shorter.

Is Lumno free and open source?

Lumno is a free, open-source browser extension. You can install it from the Chrome Web Store, read the source on GitHub, report issues, or join feature discussions.
