Try It FreeAbout Our Free B2B Tools
LemReveal's free tools give you instant access to the same intelligence infrastructure used by our paid platform — powered by 200+ data sources across company registries, technology detection, DNS analysis, and web intelligence. Each tool provides actionable data with no account required.
How Are These Tools Different?
Unlike simple WHOIS or header checkers, our tools cross-reference multiple data sources simultaneously. The Tech Stack Checker, for example, combines HTTP header analysis, DNS CNAME probing, and technology fingerprinting to detect tools that single-source checkers miss entirely.
Need to watch a record, not just look it up?
LemReveal re-checks official company registers on a schedule and emails you when a name, status, address or director changes.
