How this list is ordered. Specifiction scores each tool on how fully its maker documents it, whether its prices
are published, where the research puts it, the platforms it runs on and whether it can be tried for free (how we rank).
Makers can also buy a numbered place (how Specifiction is paid for).
Check supported platforms, pricing model, free-plan terms and trial length. If code access matters, check whether the tool is open source and review its licence.
