SOAP 2.0 is a free tool that simulates the effects of dark spots and bright plages on the surface of a rotating star, computing their expected radial velocity and photometric signatures. SOAP 2.0 is an upgraded version of SOAP that includes the convective blueshift and its inhibition in active regions.
The code is described in X. Dumusque, I. Boisse & N.C. Santos 2014, ApJ, 796, 132
as well as its use, some tests, and applications.
The source code is available for download here.
If you do not wish to download and install the code, you can also use this website to run SOAP 2.0. Use the file button to upload a .cfg file (example here) defining the stellar an active region properties, or a .tar file containing a maximum of 10 .cfg files. Then use the send button, which will process your files and provide a download of the results. The format of the results are described here.
