TabCubby

Stop losing tabs. Start working in workspaces.
TabCubby lets you save and organize your browser tabs into named workspaces — so you can switch between projects, research sessions, or client work without losing a single link.
Core features:
• Workspaces — Create color-coded workspaces for any project, topic, or context
• Save tabs instantly — Save your current tab or all open tabs to any workspace in one click
• Open links fast — Open a single link or all links in a workspace at once
• Search — Filter workspaces and links instantly by name, domain, or URL
• Dark mode — Easy on the eyes, day or night. Preference saved automatically.
• Import & Export — Back up your workspaces as JSON or move them to another device
• Deduplication — TabCubby skips links already saved in a workspace, automatically
• No account required — All data stays on your device. Nothing is sent to any server.
How it works:
Click the TabCubby icon to open the popup
Create a workspace (give it a name and a color)
Save your current tab — or all tabs at once — into that workspace
Come back any time and open links individually or all at once
Perfect for:
Researchers juggling multiple topics
Developers switching between projects
Students organizing references by subject
Anyone who opens 30 tabs and never closes them
TabCubby is free, lightweight, and built with your privacy in mind. Your data never leaves your browser.
