Choosing well
Start with access and price
A free plan can help you assess an OSINT workflow before paying. Check what access it includes and whether a paid tier is required for the searches or exports you need.
Trial lengths are not uniform: Hunchly advertises 30 days, whereas Intelligence X advertises 7 days.
Check the platform fit
Look for an Android app if you plan to work from a Xiaomi, Redmi or POCO phone or tablet. Available platform labels include web, Linux, API, Windows, macOS and extensions.
Match the search scope
Compare support for social-source search with domain and IP lookup. These cover different starting points for an investigation.
BuiltWith, DNSDumpster and Epieos are examples of names to review when comparing lookup-focused options.

When findings must feed another workflow, check whether the tool offers API connectivity and export functions.
