About these guides
How we compare software
The same plain rules apply to every guide on this site.
Method
What we use
Each vendor’s own public pricing page, product pages and documentation, plus official government sources for compliance topics. Every claim links to its source. When a vendor doesn’t publish a price, we say “quote only” rather than repeat third-party estimates.
What we don’t do
We don’t claim hands-on testing we haven’t done, publish star ratings or invented scores, or write fake reviews. If we ever test a product hands-on, the page will say what we did and when.
Affiliate disclosure
None of our guides contain affiliate links today. In the future we may join vendors’ affiliate or partner programs, which pay us a commission if you buy through our link, at no extra cost to you. If we do, every affiliate link will be labeled, this notice will name the programs, and rankings won’t depend on commissions. Vendors can’t pay to be listed or ranked.
Corrections
Spotted an outdated price? Every page shows the date we checked, and vendors change prices often, so the vendor’s own page is always the final word.
