Overview

Split your browser into layouts for comfortable webapp testing

Tilr lets you organize your browser windows into predefined screen layouts with a single click. Choose between two columns (1x2), two rows (2x1), a 2x2 grid, or a 3x2 grid (6 windows), and Tilr will automatically position your windows to fill the screen. Each panel is a real browser window with full capabilities — no iframes, no limitations. Resize any window and the others adjust automatically to keep the layout perfectly synchronized — no gaps, no overlaps. The layout stays consistent whether you're fine-tuning proportions or working across multiple monitors with independent layouts on each screen. Designed for web developers, QA testers, and anyone who needs to view multiple webapps side by side without manually resizing and dragging windows. Features: - Four layout modes: two columns, two rows, 2x2 grid, and 3x2 grid (6 windows) - Dynamic resizing: drag any window edge and all adjacent windows adapt instantly - Independent multi-monitor support: run different layouts on each screen simultaneously - Distribute your open tabs across layout windows automatically - One-click restore to regroup all tabs into one window - Windows managed as a group with automatic cleanup - Multilingual: 12 languages (English, Spanish, Catalan, Galician, Basque, German, French, Italian, Portuguese, Danish, Finnish, Dutch) - No data collection, no analytics, no external connections - Open source (GPL v3)
