Concept

No Tabs. Just persistent physical space.

Den Browser replaces ephemeral browser tabs with structured, persistent surfaces designed for long-running work.

Broad Context

Desk

A horizontal work area representing a broad task context. Switch between multiple desks instantly from the keyboard without losing your place.

Surface

Board

A focused column representing a single task. Holds either a Web Sheet stack or a live native Terminal session side-by-side.

Content

Sheet & Terminal

Web screens held within a board with persistent navigation history, or interactive Terminal, Zellij, and zmx sessions.

Orchestrate your web workflow

No more tab list clutter. Den Browser maps spatial window management directly to Desks, Boards, and Drawers.

Niri-Inspired Spatial Canvas

Inspired by the Niri scrollable tiling window manager, web tasks sit side-by-side on an infinite horizontal strip. Boards never overlap or hide behind tabs—glide smoothly across your workspace.

Integrated Terminal & Zellij

Place native shell, Zellij, or zmx terminal sessions side-by-side with your Web Boards on the same Desk. Seamlessly bridge web research and CLI tasks from your keyboard.

Built-in Content Blocking (uBOL)

Bundled with uBlock Origin Lite out of the box. Blocks intrusive ads, popups, and trackers for a lightweight, distraction-free web experience.

Keyboard-First Control

Toggle Den Mode (Ctrl + ,) or use Vim-style commands to navigate and resize boards (-/=), switch desks, and launch saved Essentials (g) purely from the keyboard.

Shared Drawer & History

Capture links opened from external apps into a Den-wide Drawer (a) without disrupting your active Desk. Preview, filter, place (p), discard (x), or restore (u) anytime.

Zen View & Focus Mode

Press z for Zen View to strip away all UI chrome, or Shift + F for Focus Mode to softly dim background boards and zero in on your active task.
