Only tools of the same or a competing category, from another vendor, count. They are ranked by their public customers at every proof level, job posts included; a tie goes to the stronger proofs (more confirmed, then more observed). Each tool shows its mix: confirmed (a case study, a press release), observed (the vendor’s customer page), signal (a job post, the weakest proof). Shared customers are shown for information and never set the order. Tools of other categories that the same companies use are listed apart, as tools used with Vector. usedby does not publish departures, so no company is shown switching from Vector to another tool.
