psignifit is a free multi-platform software package that performs maximum-likelihood fitting and significance testing for psychometric functions.

It can fit sigmoidal psychometric functions to psychophysical data taking into account possible "nuisance" parameters such as the observer's lapse rate, assess goodness-of-fit by Monte-Carlo simulation, and provide confidence intervals via bootstrap-percentile and bootstrap bias-corrected accelerated (BCa) methods.

The bootstrap-software.org website is being constructed.
