Email-lookup tools compared: Account Finder vs UserScanner, Holehe, Blackbird, Zehef, mailsleuth and Epieos
I ran the same eight email addresses through eight account-discovery tools and recorded what each one found. The raw numbers, the per-email coverage grids, and what they cost.

There are a lot of tools that take an email address and tell you where it has accounts, and most comparisons of them are hand-wavy. So I ran a small benchmark: the same eight email addresses through the same eight tools — Account Finder, UserScanner, Holehe, Blackbird, Zehef, mailsleuth, and Epieos in both its free and API forms. Below is exactly what came back, email by email. I work on Account Finder, so I've kept this to numbers you can check and left the spin out.
- Account Finder — hosted; checks ~170 services by querying each one through a real service wrapper over a pool of vetted proxies, so a hit is an actual positive response rather than a guess. On some services it also returns a little extra — an avatar, or a masked phone or email — beyond a yes/no.
- UserScanner — open-source and actively maintained; genuinely good, and the consistent runner-up on breadth here (~100 services, plus a separate username mode). Repo: github.com/kaifcodec/user-scanner
- Holehe — open-source CLI, but largely unmaintained for years and many of its site modules are now broken, which drags its numbers down. Repo: github.com/megadose/holehe
- Blackbird — open-source CLI that checks 600+ sites, but it's primarily username-oriented, so its email mode lands few. Repo: github.com/p1ngul1n0/blackbird
- Zehef — open-source CLI, deliberately narrow (~18 big platforms plus leak checks). Repo: github.com/N0rz3/Zehef
- mailsleuth — open-source CLI, narrow by design (~15 services). Repo: github.com/44za12/mailsleuth
- Epieos — hosted; its free lookup appears to cover fewer services than the paid API, and Epieos has recently shifted toward a profile-style search — detailed profile data, links to profiles, and breach/leak hits. CheckMate (checkmate.bio) is another service in that deep-profile space, with the same kind of detailed data, profile links and leak coverage. I tested Epieos's free lookup and API separately.
Each tool got the same eight addresses, one run each, no retries. Four are throwaway or well-known public test addresses (test@gmail.com, johndoe@gmail.com, test@example.com, jeevacation@gmail.com); the other four are real inboxes I have permission to check, anonymised here as two personal inboxes and two work addresses. "Found" means the tool reported a registered account on a service — nothing more.
- Same input, same day, single run per tool — no cherry-picking the best of several attempts.
- The open-source CLIs (UserScanner, Holehe, Blackbird, Zehef, mailsleuth) were run locally through the same kind of proxy pool, so they weren't throttled or IP-blocked — a fair shot, not a hobbled one.
- I didn't hand-verify every hit, so treat each count as that tool's own claim, compared on equal footing.
- Epieos's API wasn't run against the four public test addresses, so those cells read "n/t" (not tested), not zero.
Account Finder runs about $0.0033 per lookup at volume (up to $0.05 on the small plan), with a free trial; Epieos's API is roughly $0.12 to $1 per lookup, and its free lookup is free. The five open-source CLIs are free to license — but to run any of them at scale you supply and pay for your own proxy pool, or you'll be rate-limited and blocked, so "free" isn't quite free.
On speed, Account Finder held steady around 15 seconds — that's a deliberate cap: if a service hasn't responded by then it's dropped and the search returns what it has, so the runtime stays predictable regardless of the inbox. Blackbird was fastest at 3–4 seconds but returned the least; UserScanner was slowest at 40–54 seconds on the busy inboxes; Epieos landed around 9–18 seconds.
Each grid is one email. Services run down the left; every tool gets a column with its total on top, and a service sits on the same row across all columns, so you can scan across and see which tools caught it. Rows are sorted with the services most tools agreed on first, trailing down to the long tail that only one tool reached.

A fair snapshot, not a verdict. Same inputs, one run each, proxies for everyone — but coverage shifts as services change their flows, and I didn't hand-verify every hit, so any tool could have a false positive or two. Trust the shape — Account Finder and UserScanner ahead on breadth, the rest narrower — over any single cell, and run your own addresses if you want certainty.
Want free and auditable, and don't mind running and paying for your own proxies? The open-source CLIs are a good start — just check they're still maintained. Want the widest net with no setup, a predictable runtime, and a per-lookup price low enough to run in bulk or wire into a pipeline? That's the case for Account Finder. Either way, cross-check more than one tool; the overlap and the gaps are a signal in themselves.
The honest takeaway isn't "use tool X." It's that these tools disagree more than you'd expect — which is exactly why you run an email through more than one.
Account discovery is dual-use. Run it to audit your own footprint, vet a counterparty, or do authorized OSINT — not to harass, stalk, or surveil. Every tool here surfaces only publicly observable account metadata, never anything behind a login.
