unbrace

Expand Unix-style curly braces {...} in URLs and search queries into multiple browser tabs.

unbrace brings Unix-style curly brace expansion to your browser address bar and search engines. Instead of manually opening repetitive URLs one by one, enter a single pattern and unbrace will instantly expand it across multiple browser tabs. Whether you are comparing websites, checking multiple subdomains, reading numbered webcomics, or running search queries across multiple topics, unbrace automates the tedious work. KEY FEATURES Direct Address Bar Interception Type brace patterns directly into the Chrome address bar. If you enter domain patterns like {amazon, ebay, bestbuy}.com/deals or twitch.{tv, com}, unbrace automatically recognizes the addresses and opens them across tabs. If you enter search phrases like how to learn {rust, python}, unbrace generates search queries for each term on your active search engine. Omnibox Shortcut Type "ub" followed by a space in your address bar to activate unbrace directly from the omnibox. Interactive Popup Playground Click the extension icon to preview pattern expansions live before opening them. Check the total tab count or copy all expanded URLs directly to your clipboard with one click for use in curl, wget, terminal scripts, or documentation. Window and Tab Organization Choose whether expanded URLs open as background tabs in your current browser window or launch in a dedicated new window. Safety Tab Limit Built-in safeguards prevent accidental tab storms or browser freezing. Set a custom maximum tab limit (default 20, up to 100) to keep your browser fast and responsive.
