SimplePlanes for Mac

What the game offers

SimplePlanes is a sandbox flight simulator that puts realistic aerodynamics at the center of its gameplay. You create aircraft by snapping together structural components, installing engines, and shaping wing sections. After assembling a craft you can climb into the cockpit and put it through flight tests to see how it handles.

Building or jumping straight into flying

If you prefer not to design from scratch, there’s a vast community workshop with hundreds of thousands of user-created designs available for free download. The collection spans a wide range of styles — from vintage World War II bombers and contemporary jet fighters to speculative sci-fi ships — so you can take any plane for a spin immediately.

Key strengths

• Robust physics model that rewards thoughtful engineering
• Massive online library of community-made aircraft (250,000+)
• Modular parts system for custom airframe and wing design
• Direct in-cockpit testing so you can iterate quickly

A recommended alternative

Besiege (paid) is a good option if you want a different engineering-focused construction game that emphasizes creative machine design and destruction rather than traditional flight simulation.
