Detailed Review
JASP is a desktop statistics program that replaces much of what students and researchers do in IBM SPSS Statistics with menus instead of code. The JASP governing board page lists the chair and secretary at the University of Amsterdam and gives the Department of Psychological Methods in Amsterdam as the contact address.
The JASP site says the project is open source, free of charge and supported by the University of Amsterdam. We read the JASP home, about, privacy, download and features pages on 5 November 2026.
Who is behind JASP and where is it based?
The JASP community page names Prof. dr. Eric-Jan Wagenmakers (University of Amsterdam) as chair of the governing board and gives the Department of Psychological Methods, Nieuwe Achtergracht 129B, Amsterdam, as the address.
The JASP menu also lists JASP Services BV. We did not read a company register entry or an imprint for it, so the exact contracting entity for paid services is not stated in the text we read.
What can JASP do compared with IBM SPSS Statistics?
JASP offers classical and Bayesian forms of t-tests, ANOVA, regression, frequency tables, mixed models and factor analysis. The JASP feature page also lists modules for acceptance sampling, audit sampling, structural equation modelling and circular statistics.
IBM SPSS Statistics adds forecasting, decision trees, neural networks and complex-samples procedures in paid add-ons. The JASP about page says JASP deliberately does not present a large menu of exotic analyses.
Does JASP collect data from the software?
The JASP privacy policy says the JASP software itself collects no user data, so JASP neither has nor stores data of users working in the program. The policy covers the website, the forum and the newsletter only.
The JASP download page states that no internet connection is required to run JASP.
Limitations to Consider
The pages we read do not name the legal entity behind JASP Services BV, and the licence name is not stated in the text we read. JASP states that it avoids a large menu of exotic procedures, so users of SPSS add-ons for forecasting or neural networks may find gaps. JASP has a minimum of 4 GB of RAM and about 4 GB of disk space.
Who Should Use JASP
Students and researchers who want a free, menu-driven alternative with Bayesian options, for example in psychology and social science. A larger team that needs paid vendor support will find no price list on the pages we read. Users who prefer scripts can also look at R.

Frequently Asked Questions
Yes. The JASP download page says it is available entirely for free, no strings attached.
The JASP home page says JASP is an open-source project supported by the University of Amsterdam in the Netherlands.
Yes for many standard analyses. JASP is based in Amsterdam, and IBM SPSS Statistics is sold by International Business Machines Corporation in Armonk, New York. IBM sells forecasting and predictive modelling add-ons that JASP does not list.
