I already use website auditor from seo powersuite fro which I own a lifetime licence (yay me!)

I wanted something that was closer aligned to screaming frog in the way it presents data. Netpeak is close to perfect in that regard.

What I really like about it it the scraping capabilities, you can look for footprints amongst websites and work out which sites in your list are for example powered by a specific CMS so that you can target those website owners with a suitable offer. This is something I don't have in website auditor.

Netpeak also gives pretty reports to send to clients, which is something not offered in screaming frog.

I will say that in my experience, there have been times when the software felt laggy and struggled on my pc. I have a pretty decent custom built gaming rig so it really shoudn't! However nothing I can't deal with and maybe a few adjustments of the settings will fix that for me, less threads perhaps.

The support is great, they answered my question in regards to not being able to see broken links in my report pretty quickly and were very friendly.

I went for a single licence, it is more than enough for my needs considering I already own a tool that can capture email data on sites etc so have no real need for that. The price for a single licence is a steal so get in there now as time is running out!
