TabCascade

Open many URLs at once—in order, as discarded tabs, with a delay, or instantly. Includes favorites, history, and a side panel.

Open dozens—or hundreds—of URLs without losing control. TabCascade is a fast, flexible URL batch opener that helps you organize and launch large URL lists directly from Chrome’s side panel. Open tabs sequentially, with a custom delay, as discarded tabs, or all at once. ✨ KEY FEATURES 🚀 Flexible batch opening Choose how your URLs are opened: in order, with a delay, instantly, or one after another in the same tab. 💤 Discarded tabs Create tabs without loading them immediately. They only load when you select them, helping reduce memory and CPU usage. 📋 Easy URL input Paste one URL per line, import a TXT or CSV file, collect URLs from your open tabs, or use selected text from the active webpage. 🧹 Automatic cleanup Detect invalid entries and remove duplicate URLs before opening your batch. ⏯️ Full batch control Pause, resume, or stop delayed opening at any time. Failed URLs are clearly listed and can be retried individually or together. 🗂️ Smart tab grouping Keep opened tabs in a single Chrome tab group or automatically organize them by domain. ⭐ Favorites Save frequently used URL lists and reopen them whenever you need them. 🕘 Local history Quickly access previously opened batches. History and favorites remain stored locally in your browser. 🔖 Bookmark open tabs Save all suitable tabs from the current window into a new bookmark folder with one click. 📥 Import and export Import URL lists and favorites or export them for backup and reuse. 📋 Clipboard tools Copy complete URL lists to your clipboard instantly. 🪟 Side panel or standalone window Use TabCascade inside Chrome’s side panel or open it in its own compact window. 🎨 Custom appearance Choose between light, dark, and system themes and personalize the interface with different accent colors. 🔐 PERMISSIONS TabCascade requests only the permissions required to provide its core features: 💾 Storage Stores your settings, URL drafts, favorites, and opening history locally in your browser. 🗂️ Tabs Creates, updates, reloads, discards, collects, and organizes tabs based on your actions. 🧭 Web Navigation Detects whether URLs opened by TabCascade have finished loading or failed, allowing ordered batches and retries to work correctly. 📚 Tab Groups Organizes opened tabs into a single group or separate groups based on their domains. 📌 Side Panel Displays TabCascade’s main interface inside Chrome’s side panel. ⚙️ Scripting Temporarily runs bundled extension code to manage ordered or discarded tabs and to capture selected webpage text when explicitly requested. 📋 Clipboard Copies URL lists to your clipboard when you use the copy function. 🔖 Bookmarks Creates a bookmark folder from your currently open tabs when you select the bookmark feature. 🖥️ Display Information Positions TabCascade’s optional standalone window within the available screen area. 🌐 Website Access Allows TabCascade to manage user-requested HTTP and HTTPS URLs during ordered, delayed, or discarded tab opening.
