Dev-focused ultrawide window manager & screen share
A cross-platform desktop application that provides context-aware window tiling for developers on ultrawide or large single monitors, combined with region-based screen sharing for video calls. It recognizes development workflow patterns (IDE, terminal, browser, docs) and automatically arranges windows, while allowing users to share only a portion of their screen during calls.
Why this matters
You invested in a beautiful ultrawide monitor, but now your workflow is full of friction. Full-screen apps look terrible stretched across 34 inches. During video calls, you awkwardly share your entire wide display, making everything unreadable for colleagues. Your operating system treats the ultrawide as one giant screen, so snapping windows into useful layouts requires tedious manual dragging. You know that macros and key bindings could speed things up, but configuring tiling window managers is a project in itself. You wish there was a tool that just understood how you code and arranged your windows accordingly, while also letting you share just the relevant portion of your screen during meetings.
- · Built for Software developers and engineers who use ultrawide monitors or large single displays (27-42 inch) and regularly participate in video calls where they need to share their screen.
- · Most likely monetization: SaaS subscription with one-time perpetual license option.

- Implement region-based screen capture using ScreenCaptureKit (macOS) and Graphics Capture API (Windows)
- Build virtual camera integration for sharing screen regions in Zoom, Teams, and Google Meet
- Add keyboard shortcut system for快速 switching between layout presets
- Create onboarding flow with preset layouts for common dev workflows (coding, debugging, pair programming)
- Package MVP for beta distribution and recruit 20 developers for initial testing
Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1Established free tools (FancyZones on Windows, Rectangle/Yabai on macOS) already solve basic window tiling, and users may not perceive enough additional value from context-aware features to pay
- 2Region-based screen sharing may require virtual display drivers or virtual camera plugins that conflict with corporate security policies or enterprise MDM restrictions
- 3Maintaining compatibility across macOS and Windows OS updates is resource-intensive, and a single breaking change could cause mass churn
Evidence Summary
How AI synthesized this insight — no verbatim quotes
Across the discussion, multiple developers independently reported that screen sharing during video calls is problematic on ultrawide displays, with 3+ mentions of this specific pain. Several users noted that fullscreen applications behave poorly on extra-wide panels, and that operating systems handle window placement inadequately. The recurring theme that productivity comes from reducing interface friction rather than buying hardware appeared in 2+ comments, yet no dominant software solution exists. Users also reported spending significant budgets on workspace equipment ($1,000+), indicating capacity to pay for tools that enhance their investment.

Who It's For
For Software developers and engineers who use ultrawide monitors or large single displays (27-42 inch) and regularly participate in video calls where they need to share their screen
Feature List
✓ Development-context-aware window tiling (detects IDE, terminal, browser, docs) ✓ Region-based screen sharing for video calls (share a portion instead of full ultrawide) ✓ Virtual monitor partitioning for large displays with independent per-region behavior ✓ Community-shared layout templates for popular IDE and workflow configurations ✓ Per-app fullscreen-aware tiling that respects ultrawide dimensions
