Before you pay, check three things on each tool page: what the free plan leaves out, what the plan costs after the first term, and which platforms the tool runs on. Each page links the vendor's own pricing source so you can confirm the figures yourself. Tools are sorted by Tools.us.org score, highest first, with ties broken by the number of ratings. The score summarizes published ratings only; this page reports recorded facts and is not a hands-on test.
