Email, username and domain OSINT in one workflow.
Start with an identifier you already have. Opsis checks the relevant sources, then organizes the available findings so you can follow up on the ones that matter.
Email search
Start with an email address to check for associated accounts. Where a source exposes public profile data, review names, usernames, photos and profile links alongside the result.
Username search
Look for a handle across social networks, developer communities, gaming sites and more. Compare the available profile details: the same username on two sites does not prove it is the same person.
Domain search
Investigate a domain with WHOIS, DNS and reverse WHOIS lookups. Premium document metadata analysis can add context from publicly available files when those files are accessible.

700+ modules. Every major platform.
Username lookups, email enrichment, and domain OSINT — all against verified, maintained modules across social, gaming, dev tools, and crypto.
Better signal than the alternatives.
Most username scanners drown in false positives, miss the data that matters, or both. Here's what we did differently.
Verified hits, not guesses
Most scanners flag any HTTP 200 as “found” — even a generic “user not found” page. Opsis requires real profile signals (avatars, display names, structured data) before it counts.
Sources we actually maintain
OSINT sites change constantly — HTML restructures, APIs deprecate, modules go stale. We continuously monitor and repair our 700+ modules so they work when you query them.
Profile data, not checkmarks
A green check is the start, not the end. Opsis pulls avatars, names, bios, follower counts and join dates so you see who an account belongs to.

Questions about searching with Opsis.
What is an OSINT search platform?
An open-source intelligence (OSINT) search platform brings information from multiple publicly accessible sources into one workflow. Opsis starts with an email address, username or domain and organizes the available findings for you to review.
How is Opsis different from a search engine or a tool directory?
A web search engine finds indexed pages; a tool directory points you to other tools. Opsis runs source-specific checks and brings the results into one report, with public profile information where it is available.
Does a match confirm someone’s identity?
No. Account-existence signals and public profiles are leads, not proof of identity. Compare names, photos, links and other context before drawing a conclusion. A missing result also does not prove an account is absent: sources can be private, unavailable or rate-limited.
Do I need to install anything or know how to code?
No. The Opsis web app runs in your browser. Create an account, select a plan, then choose a search type and enter the identifier you want to investigate. API access is available on Pro for programmatic searches.
