Markov Side-by-Side
Interactive tools for simulating stochastic processes directly in the browser. No installation required — define your model and run.
Reaction Network Designer
CTMC Gillespie
Exact stochastic simulation of biochemical reaction networks. Define species, parameters, and transitions — the Gillespie algorithm draws exact inter-event times.

Time-Dependent Simulator
Fixed Time-Step CTMP
Simulate continuous-time Markov processes with time-varying rates. Define arbitrary f(t) helper functions and use them directly in your transition rates.
Presets: Waning Birth, Seasonal Lotka-Volterra
SDE Solver
Euler-Maruyama Method
Numerically solve systems of stochastic differential equations dX = f(X,t)dt + g(X,t)dW. Run multiple realizations simultaneously to visualize path distributions.
