Busca

A fast, keyboard-first command palette for Google Chrome.

Search your tabs, history, and bookmarks, run quick actions, and jump anywhere - without touching the mouse.

Features

One palette, two ways to open it:

Trigger	What it does
Cmd+T / Ctrl+T	Opens Busca as your new tab page
Cmd+K / Ctrl+K	Opens Busca as an overlay on any page

• Unified fuzzy search across open tabs, history, and bookmarks - ranked omnibox-style so your most-used result lands first, with inline autocomplete.
• Paste-to-navigate - paste a URL and press Enter to go straight there, just like the address bar.
• Bangs - type / for a picker (/g Google, /y YouTube, /w Wikipedia, /gh GitHub, /so, /npm, /mdn, /ddg), or add your own.
• Quick actions - clear cache (last 24h, or cache + cookies for the current site), reopen the last closed tab, duplicate or mute the current tab, open Chrome pages, a new incognito window, and more.
• Google apps launcher on the new tab (Gmail, Drive, Docs, Sheets, Calendar…).
• Real favicons on every result and bang.
• Preferences page - accent color, the empty-state layout, which tools appear, and custom bangs - synced across your Chrome.

Tech stack

• Preact + @preact/signals - tiny, fast UI
• TypeScript
• uFuzzy - fuzzy matching
• Hand-authored CSS rendered in a Shadow DOM overlay (host-page styles can't break it), with Hanken Grotesk + Geist Mono bundled
• Vite + @crxjs/vite-plugin - Manifest V3 build
• chrome.storage.sync for preferences

Local development

1. Prerequisites

• Node.js 18+ and npm

2. Clone and install

git clone https://github.com/NinyaDev/Busca.git
cd Busca
npm install

3. Build the extension

npm run build

Use npm run dev instead for a hot-reloading build while developing.

4. Load it in Chrome

1. Open chrome://extensions
2. Enable Developer mode (top-right)
3. Click Load unpacked and select the dist/ folder
4. Press Cmd+T / Ctrl+T for the new tab, or Cmd+K / Ctrl+K on any page

Important

Load the npm run build output. The npm run dev build streams from a local dev server and stops working once that server is closed.

Project structure

src/
  shared/      types, messaging, bangs, quick actions, preferences
  core/        the palette UI - search, ranking, icons, styling
  background/  service worker - builds the search index, runs actions
  newtab/      new-tab adapter (Cmd+T) + Google apps launcher
  content/     overlay adapter (Cmd+K)
  options/     the preferences page
manifest.config.ts

It's intentionally simple: one palette component mounted on two surfaces, and one service worker that builds the search index and runs every action.

Privacy

Busca is 100% local. There is no backend, no analytics, and no telemetry.

• Your tabs, history, and bookmarks are read on-device to power search and never leave your machine.
• Favicons come from Chrome's own local cache.
• Preferences are stored with chrome.storage.sync - kept on your device and synced through your own Chrome account, never to any server we control.
• The only network requests are the ones you trigger by opening a result or running a search - i.e. ordinary browsing.
