  • OS: Windows 10+ (x64)
  • RAM: 4 GB minimum (8 GB+ recommended)
  • Storage: ~500 MB for app + ~1 GB for Python backend
  • Python: 3.10+ (bundled in installer)
MacOS and Linux support are on the roadmap. Windows is the primary target.

Installation

Option 1: Download the Installer

  1. Go to GitHub Releases and download LastBrowser-Setup-x.y.z.exe.
  2. Run the installer. Choose your installation directory (or keep default).
  3. A desktop shortcut and Start Menu entry are created automatically.
  4. Launch LastBrowser from the shortcut.

Option 2: Portable Version

Download LastBrowser-Portable-x.y.z.exe. No installation needed — run directly from any folder.

Option 3: Build from Source

See Building from Source below.

First Run

When you launch LastBrowser for the first time:

  1. Splash Screen — "Starting LastBrowser" with loading modules.
  2. Main Window — Dark-themed interface with sidebar and content area.
  3. Server Status — Python backend starts automatically. Status shows "connected" when ready.

From here you can create workspaces, configure AI agents, pin web apps, start browsing, and open the Command Palette (Ctrl+K).

Setting Up Workspaces

Each workspace has its own tabs, cookies, apps, and kanban boards — fully isolated.

Create a Workspace

  1. Click + in the workspace switcher (top of sidebar).
  2. Name it, pick an emoji icon, choose an accent color.
  3. Switch between workspaces by clicking their names.

Manage Workspaces

  • Rename: Right-click and select Rename.
  • Reorder: Drag and drop in the switcher.
  • Pause: Free up resources for inactive workspaces.
  • Export/Import: Share workspace configurations as JSON.

Navigation hub with one-click access to all panels:

  • Chat — Interact with AI agent
  • Kanban — Task management boards
  • Agents — AI agent configuration & monitoring
  • Browser — Vertical tab browsing
  • Memory — Agent memory and recall
  • Skills — Manage agent skills
  • Settings — App configuration

Use Ctrl+B to toggle sidebar visibility. The bottom footer shows server connection status.

Configuring AI Agents

  1. Open the Agents panel.
  2. Click Add Agent and configure: name, model (e.g. deepseek-v4-flash), provider, max tokens, temperature, role.
  3. Enable the agent and assign it to tabs or tasks.

Agent dashboards show real-time stats: total tasks run, tokens used, success rate.

Using Kanban Boards

  1. Navigate to the Kanban panel.
  2. Click New Board — default columns are created (Inbox, Todo, Planned, In Progress, etc.).
  3. Drag cards between columns. Set WIP limits on columns.

Focus Mode

Built-in Pomodoro system: Pomodoro (25m), Focus 50 (50m), Focus 90 (90m), Short Break (5m), Long Break (15m). When active: notifications muted, badges hidden, sounds muted.
