Alternative.me

Alternative.me builds pages around software replacements, capturing searches from people actively looking to switch tools.

Submission is reported free with editorial review, and outbound links are reported dofollow — a rare combination among comparison sites, most of which nofollow product links. Reviews are supported on listings.

With DR 75 and roughly 1.1M estimated monthly visits, it is one of the better free listings available for SaaS: real comparison traffic and a link that counts. Position the entry against the specific tools you replace.
