Window View
When the decision hinges on what you can actually see from a specific unit, Window View is purpose-built for the job. Instead of emphasizing roof surfaces and solar metrics, it focuses on a floor-and-window workflow so you can place a window on any wall and verify real sightlines and nearby obstructions.
That makes it especially useful for comparing apartments in the same building, where a small change in height or orientation can dramatically change the view. The sun path overlay adds a practical layer for understanding when direct sunlight will hit a window, helping answer “will this room get morning sun?” faster than a more general shadow visualization.
Window View also stands out for being open-source and free, which is appealing when you want quick answers without accounts, contracts, or team licensing. The main trade-off is that unit-level placement often requires manual input, but that same granularity is exactly what makes it valuable for renters, buyers, and agents who care about the window-level reality, not just the building footprint.
