Our verdict on OSINT.sh
OSINT.sh is a web-based collection of information-gathering and network-security tools for investigators, analysts, and developers working with domain and infrastructure data. Its Reverse WHOIS tool links domain names to an email address, while the API supports searches using an email address, name, or keyword. The service also covers historical WHOIS records, reverse domain searches by keyword, reverse IP lookup, DNS history, and certificate search. Web and API access are available, with API usage organized around monthly credit plans.
Pricing is structured across three monthly tiers. Proletar costs $50 per month and includes 1,000 Whois History credits, 1,000 Reverse Whois credits, 4,000 DNS History credits, and 10,000 credits for all other tools, plus 24/7 email support and 1 IP authorization. Middle Class costs $200 per month and increases those allocations to 6,000, 6,000, 30,000, and 60,000 credits, respectively, while keeping 1 IP authorization and 24/7 email support. Borjuis costs $500 per month and provides 20,000 Whois History credits, 20,000 Reverse Whois credits, 100,000 DNS History credits, 400,000 credits for all other tools, 24/7 email support, and 5 IP authorizations.
The main strength is breadth around domain intelligence: reverse WHOIS is supported by historical records, DNS history, reverse IP, certificates, and keyword-based domain discovery. That makes OSINT.sh a practical fit for API users whose workflows pivot from email addresses or keywords into related infrastructure. The trade-off is the credit-based structure, which requires buyers to match plan capacity to query volume. IP authorization is also limited to 1 on the two lower-priced plans, so teams requiring 5 authorizations need Borjuis. Choose OSINT.sh when email, name, keyword, and historical domain pivots matter; buyers needing only a narrow single-purpose lookup may not need its wider toolset.
