jamovi vs JASP

jamovi is a free, open-source statistical analysis program for working with data through point-and-click controls or scripting. It supports statistical tests, regression models, and Bayesian analysis, and imports SPSS (.sav), SAS, Stata, CSV, and Excel files. The spreadsheet-style interface lets users choose variables and settings, with results updating as they work; analysis does not require writing code. The desktop application runs on Windows, macOS, and Linux, and works offline after installation. Cloud access runs in a browser without installation or setup, including on modern browsers, Chromebooks, lab computers, tablets, and other devices. The free Cloud Guest plan requires no credit card, but guest sessions lack queue skipping, unlimited session length, longer idle timeouts, and larger datasets. jamovi is powered by R and displays the R syntax behind analyses. Data, analyses, and results can be saved together in a shareable, reproducible file. Cloud can connect to OneDrive to open and save jamovi files; Cloud plans include the full module library.

JASP is free desktop statistical software for Linux, macOS, and Windows, designed to run analyses through a graphical interface without programming. It offers standard procedures in both frequentist and Bayesian forms, with modules for descriptives, t-tests, ANOVA, regression, meta-analysis, machine learning, structural equation modeling, survival, and time series. The spreadsheet-style interface uses drag-and-drop controls, and results update as analysis options change. JASP produces APA-formatted output, including tables that can be copied into a word processor, and lets users annotate results. It is integrated with the Open Science Framework and can run without an internet connection. Import formats include CSV, TSV, text, SPSS, SAS, Excel, Stata, and R files, among others. JASP requires a 64-bit operating system, about 4 GB of free disk space, and at least 4 GB of RAM; 8 GB is recommended, with 16 GB or more suggested for large datasets. Android, iOS, and iPadOS devices are not supported. The software uses the GNU Affero GPL v3 license, and its download page says it will remain free.
