## Tools in this category

Ranked by verified rating first among the 3 tools with at least 5 published reviews, then by the number of teams using the tool. A tool with fewer than 5 reviews is listed after those, ranked by adoption instead, never allowed to outrank a well-reviewed tool on the strength of a thin average. Fewer than 10 tools in this category currently clear that floor, so treat this as an early signal, not a mature ranking. Ratings come from professionals who verified a work email at the organization named in their review. Among the 26 vendor tools Soft Atlas tracks in this category, an entry marked "not yet rated on Soft Atlas" has no published review yet, it is listed, not scored as zero.
