The Mock LISA Data Archive aims to provide realistic simulations of the output from the LISA observatory to interested researchers developing algorithms for analyzing LISA data.
LISA simulator is open-source software for simulating by the response of LISA to a gravitational wave signal (N. Cornish & L. Rubbo).
Sensitivity curve generator: An online tool that can be used to explore the average sensitivity
characteristics of any equal arm observatory operating in the standard
Michelson mode.
Synthetic LISA is a public-domain package for simulating the LISA science process (M. Vallisneri & J. Armstrong).
