Sketch the plan
Draw walls, zones, openings, dimensions, and annotations on a precise 2D canvas.
Ostrid Design · public alpha spatial design software
Ostrid Design turns floor plans into spaces you can step inside.
Ostrid turns floor plans into walkable 3D spaces. Sketch in 2D, see them update live, and walk through rooms, routes, and ideas before they become finished models.
Public alpha: expect rough edges, incomplete tools, and breaking changes. Early testers help shape the first stable release.
The problem
Floor plans are useful. But they're hard to feel.
A room can look right from above and still feel cramped, confusing, or lifeless when you move through it. Most tools separate planning from experience, making it harder to understand scale, flow, and movement early in the process.
- Static drawings hide spatial feeling.
- 3D tools can be slow for early layout ideas.
- Game engines are powerful, but not made for quick floor-plan sketching.
The solution
Sketch the plan. Walk the space.
Ostrid connects a simple 2D floor plan editor with a live 3D walkthrough. Draw walls, shape rooms, adjust layouts, and step inside the result without switching tools.
It sits between CAD and game engines: precise enough for spatial thinking, playful enough to feel like exploration.
The current alpha workflow
From floor plan to footsteps.
Preview the space
See floors, slabs, height, and openings update live in a 3D preview as the plan changes.
Walk the idea
Drop into Walk Mode and move through the space in first or third person to test scale, flow, light, and spatial feeling.
Built for spatial thinkers
For people who think in rooms, routes, and light.

Where things stand
A working alpha, not a finished building editor.
You can already experiment with walls, roofs, stairs, multi-floor structures, materials, live 3D, and walkthrough mode. These systems are still being tested and may be incomplete or unreliable with real projects. Ostrid is not yet a replacement for production CAD or construction documentation tools.

Questions, answered early.
What is Ostrid?
Ostrid is an early public-alpha spatial design tool for sketching floor plans in 2D, previewing them in 3D, and testing walkable spaces.
Is Ostrid available now?
Yes, as a public alpha. You can sign in and try it now, but features, file compatibility, and workflows may change or break while we work toward a stable release.
Who is Ostrid for?
Spatial design students, level designers, interior layout explorers, architects, concept designers, and hobby builders — anyone who thinks in rooms, routes, and light.
Is Ostrid a CAD tool?
Not exactly. Ostrid sits between CAD and game engines. It's focused on quickly sketching and experiencing space, not replacing full technical drawing tools.
Will Ostrid run in the browser?
Yes. Ostrid is a web-based spatial design tool, so you can create and explore spaces without any heavy setup.
