All 12 Browser Simulators
Every canonical agent-based model, running live in your browser. Hover any tile to see the model in motion — then click to open the full simulator.
Schelling Segregation
Mild preferences produce extreme sorting. The founding example of emergence in social science.
SEIR Epidemic
A pandemic in your browser. Tune R₀ and recovery — watch the curve bend.
Boids Flocking
Three rules, hundreds of agents, emergent murmurations. The visual payoff of ABM.
Wildfire Spread
Cellular-automaton wildfire with wind and humidity. Paint firebreaks and route the fire.
Voter Model
Binary opinion dynamics. Zealots, media, and drift decide consensus or polarization.
Sugarscape
The Epstein–Axtell economy. Pareto wealth distribution emerges from simple harvest rules.
Conway's Game of Life
Two rules. Three states. One of the most surprising systems in all of computing.
Predator-Prey
Wolves, sheep, grass. Three populations locked in Lotka-Volterra oscillation.
Hospital Capacity
SIR with finite beds. Watch the curve overwhelm capacity — and mortality spike.
Bus Route Simulator
Passengers arrive, buses cycle. Bus bunching forms on its own — unless you design against it.
Spatial Cooperation
Prisoner's dilemma on a lattice. Nudge temptation past 1.50 and watch defection sweep.
Traffic Intersection
A 4-way signalized intersection. Tune phases; find the timing that minimizes wait.
Try Schelling segregation, right here
Drag the tolerance slider below 0.3 — the grid stays mixed. Push past 0.35 — watch neighborhoods lock into clean blocks. The 1971 model, fully interactive.

Epidemic Simulation
SEIR/SEIRD models with age-structured populations, spatial mobility, vaccination campaigns, behavioral adaptation, and variant emergence. Simulate city-scale outbreaks with millions of agents. Powered by FLAME GPU 2.
Traffic & Mobility
Microscopic intersection simulation and city-wide origin-destination modeling. Import road networks from OpenStreetMap. Test signal timing, transit routes, and autonomous vehicle scenarios. Powered by FLAME GPU 2.
Social Dynamics
Classic ABM models at GPU scale: Schelling segregation, opinion dynamics, wealth distribution, cooperation games, cultural diffusion. Run the canonical models from your browser with millions of agents.
Ensemble Sweeps
Run hundreds of parameter variations simultaneously across multiple GPUs. Compare scenarios side-by-side. Get publication-ready charts and auto-generated methodology text for your paper.
Who uses SimLab

Epidemiologists
Simulate disease outbreaks across realistic synthetic populations. Run intervention scenarios. Connect to SciRouter's drug discovery tools for end-to-end pandemic response.
Social Scientists
Run the classic ABMs at scales your laptop can't handle. Schelling with 10 million agents. Voter models on million-node networks. Ensemble sweeps for statistical robustness.
FAQ
What is FLAME GPU 2?›
FLAME GPU 2 is an open-source GPU-accelerated agent-based modeling framework from the University of Sheffield. SciRouter hosts it so you don't need CUDA or GPU hardware — just call the API.
How many agents can I simulate?›
Free tier supports up to 100,000 agents. Pro (5M agents) and Agentic/Enterprise (50M+ agents) unlock larger simulations on dedicated GPU instances.
Can I build custom models?›
Yes. The visual rule builder lets you define agent types, properties, and behaviors without code. Pro users can also upload Python model definitions for full flexibility.
How does this connect to SciRouter's other tools?›
SimLab results can feed directly into SciRouter's molecular tools. Simulate an epidemic, then screen antivirals with DiffDock and ADMET-AI — same platform, same API key.
What does it cost?›
SimLab uses the same credit system as all SciRouter tools. A basic simulation run costs 5-20 credits. Ensemble sweeps cost more based on number of runs. Free tier gets 500 credits/month.
Can I use it for teaching?›
Absolutely. The canonical model library is perfect for ABM courses. The auto-generated methodology text helps students learn proper scientific documentation. Contact us for classroom site licenses.
