Shaded rows are where the two answers disagree and both listings have answered. A row where one side has not stated a fact is left plain, because silence is not a difference.
Serpstat
A full SEO suite at fifty dollars a month
Serpstat does keyword research, rank tracking, backlink analysis and site audits from one account, and prices the entry plan below where the better-known suites start. The data is thinner in some markets than Ahrefs or Semrush, which is the honest trade for the difference. For somebody checking a few hundred keywords a month rather than running an agency, the cheaper tier is not a compromised version of the tool, it is the same tool with lower limits.
Our note
The data is thinner than the market leaders in some regions, and that gap is the whole difference in price. Run the trial against keywords you already know the answer for, because that comparison tells you in an afternoon whether the cheaper tier is enough.

Sitebulb
A crawler that explains what it found
Sitebulb crawls a site and returns prioritised issues with an explanation of why each one matters, which is the difference between this and a spreadsheet of URLs. Crawl maps draw the structure of a site as a picture. JavaScript rendering is on every plan rather than reserved for the dearest. The desktop product audits ten thousand URLs at the entry tier, so anybody auditing a large site is looking at the cloud version instead.
