I've recently updated the SPM software list, with a couple of new (to me) programs, Mountains and TrueMap. Both are based on profilometer software, but also offer to open AFM files. Since profilometry and AFM produce very similar data, this makes sense, and both are capable programs, though I found mountains more flexible in opening AFM file formats. However, since AFM and profilometry tend to be used for different samples, the requirements can be somewhat different, and most AFM-specific packages are more flexible in for example levelling procedures, which are very important. The links to the programs can be found on the software page.
