StochKit is an extensible stochastic simulation framework developed in C++ that aims to make stochastic simulation accessible to practicing biologists and chemists, while remaining open to extension via new stochastic and multiscale algorithms. StochKit currently supports Linux, Windows, and OS X.

StochKit version 2.0.* contact:

StochKit2 performs stochastic simulations using Gillespie's SSA (and variants). It was developed by Professor Linda Petzold's research group at the University of California, Santa Barbara.

There are 3 versions: Windows (full) version (, Windows "lite" version with limited functionality (, and the Linux/Unix/Mac OS X version (StochKit2.tgz).
