Every comparison here is built from published facts — pricing structure, feature lists, and documented terms taken from each vendor's own site — with the source URLs listed on the page and the month they were checked at the top. Where a vendor does not publish a limit, we say so rather than guess. Each page includes a straight “choose them if” section for every tool, because a comparison that only argues one way is not worth reading.
