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).

Before choosing, compare free access, paid pricing and trial terms. Check for social source search, domain and IP lookup, monitoring and alerts, link analysis, API access, data export and the platforms you use.
