New Visual event layout simulator is live

Will this
setup
become
chaotic?

Design your event or store layout. Run a crowd simulation. Watch bottlenecks form before they happen.

Three steps from blank room to bottleneck insight

No CAD experience. No engineering degree. Just a browser and 5 minutes.

01

Build the layout

Pick a room type — gym, cafeteria, store, outdoor. Drag and drop tables, booths, barriers, checkout stations, and signs. Resize, rotate, label each one.

02

Set entrances and zones

Drop doors on room edges. Assign arrival percentages per door. Draw invisible zones — Browse, Checkout, Pickup — and set dwell times and visit probabilities for each.

BROWSE CHECKOUT 55% visit avg 3min
03

Simulate and analyze

Set total visitors and arrival curve. Hit Run. Watch simulated families flow through your layout. When the simulation ends, see heatmaps, wait times, and specific bottleneck warnings.

Drag. Drop. Label. Done.

No tutorial needed. Choose a room preset, drag components from the library, and you're simulating in under 5 minutes.

  • 5 room presets: Gym, Cafeteria, Hallway, Store, Outdoor
  • 12+ object types: tables, booths, barriers, checkout stations, signs, walls
  • Every object: draggable, resizable, rotatable, labelable
  • Set dimensions in feet or meters. Accurate scale, not a sketch.

Watch it unfold in real time

Families enter through your doors, browse your zones, queue at checkout, and exit. No physics degree required.

  • Visitors spawn as families, not individuals — more realistic for community events
  • Agents pathfind around obstacles, avoid collisions, queue naturally
  • Arrival curves: steady, front-loaded, or random spikes — model your actual event
  • Speed up to 10x to stress-test busy periods

Concrete answers, not pretty charts

Stop guessing. Get specific, actionable recommendations backed by the simulation.

Checkout congestion detected. Move pickup station behind the checkout counter — reducing crossover traffic can cut average wait time by over a third.

Not just one use case. Dozens.

School PTA Events

Plan carnival layouts, pickup table positions, and entry flows for meet-the-teacher nights and school fundraisers.

Pop-up Retail

Test your booth layout before the market opens. Know which products need more floor space and where to put signage.

Dog Adoption Events

Design the kennel layout, waiting areas, and meet-and-greet zones to reduce stress on animals and visitors alike.

Vendor Fairs

Balance foot traffic across aisles. Position high-traffic vendors to prevent dead zones and crowding at popular booths.

Farmers Markets

Simulate stall placement and flow patterns before market day. Adjust layout to prevent congestion at popular vendor spots.

Concession Stands

Test queue barrier placement, counter positions, and service lane configurations before the game starts.

The problem

Every event organizer
eventually learns this
the hard way.

You spend weeks planning a school fundraiser. You set up the gym exactly like last year. And then, 400 people show up and it all falls apart.

The checkout line snakes into the browsing area. Nobody can find the shirt pickup. Someone trips over a queue barrier. You improvise for two hours.

Professional simulation tools exist. MassMotion. PTV Viswalk. Legions. They cost $10,000 a year and require a week of training to use.

That's for architects designing airports. Not for the mom organizing a PTA carnival.

We built CrowdSim because the gap between "a blank room and a chaotic event" should not be a guessing game.

Will this setup
become chaotic?

Stop guessing. Build your layout, run the simulation, and know before you set up.
