The shortlist
LeakCheck is built for fast lookups by email, username or phone number. Teams usually start comparing when an investigation needs more: every exposed account of a domain at once, the service a stolen password was used on, raw leak files or dark web forum posts. Each tool below is described from its own documentation, and each entry says when it is the better fit.
At a glance

| DeHashed | Field-by-field breach lookups with WHOIS tools | LeakRadar vs DeHashed ↗ |
| Snusbase | Querying breach tables and hashes through an API | LeakRadar vs Snusbase ↗ |

Why teams look beyond LeakCheck
LeakCheck answers one question quickly: has this email, username or phone number appeared in a known leak? Its paid plans add breach monitoring, alerts to Telegram, email, Slack, Discord or webhooks, and API access.
According to its pricing page, domain monitoring, reverse search by password and domain, info-stealer log search by website and BulkCheck are listed on the Enterprise plan only. Teams that need these features for a whole organization often compare the workflow and the cost with other tools before upgrading. [3]
How we compared
We read each vendor's public product pages and documentation, then compared the same three points for every tool: what you can search, the context you get for each match, and what happens next (alerts, exports, API). We did not run a coverage benchmark: the size of a database says little about how many useful matches it holds for your own domain. Test that with the same authorized scope in each tool.
Data methodology ↗- 01Best for
LeakRadar
Domain and account investigations across stealer logs, combolists, raw files and dark web forums
LeakRadar starts from a domain or an email address. Domain results are sorted into employees, third parties and customers, and each stealer-log record keeps the service URL where the credentials were captured. Monitoring alerts go to Email, Slack, Discord, Telegram or a webhook, and large exports run as background jobs in CSV, TXT or JSON. Credentials stay masked until you unlock them, and the available datasets depend on your plan.
- Research scope
- Search stealer logs (url:user:pass), combolists (email:pass / user:pass), raw leak files and dark web forum posts, according to your plan.
- Investigation context
- Inspect the exposed password alongside the account and, for stealer logs, its service URL. When the source includes plaintext, that detail helps your team scope password resets and investigate exposed access.
- Follow-up
- Get notified via Email, Slack, Discord, Telegram or Webhook when new exposed credentials match your monitored domains or email addresses. Examine plaintext passwords and service URLs. Export CSV, TXT or JSON, or connect your security tools through the REST API.
- 02Best for
DeHashed
Field-by-field breach lookups with WHOIS tools
DeHashed is the closest to LeakCheck's lookup model: you search breach records by fields such as email, username or IP address. It adds WHOIS tools for domain and infrastructure context, and domain monitoring with email and webhook notifications.
- Research scope
- Search across fields such as email, username and IP address. [4]
- Investigation context
- WHOIS tools add domain registration and infrastructure context. [7]
- Follow-up
- Domain monitoring with email and webhook notifications. [5]
- 03Best for
Snusbase
Querying breach tables and hashes through an API
Snusbase suits analysts who prefer to query breach data directly. Its API supports multi-field and wildcard searches with source-table filters, plus combo, hash and WHOIS lookups, and API access comes with paid membership.
- Research scope
- Searchable breach data, combolists and previously cracked password hashes. [8]
- Investigation context
- API searches support multiple fields, wildcards and source-table filters. [9]
- Follow-up
- API endpoints include combo, hash and WHOIS lookups for custom workflows. [9]
- 04Best for
Intelligence X
Historical archives beyond credentials
Intelligence X covers more than credentials: archived web content, leaks and dark web material across many source categories. Its Identity Portal returns line-level results and leaked-account exports. Licenses are split between research, API, Identity Portal and enterprise use.
- Research scope
- Search across archived web content, leaks, dark-web material and other source categories. [10]
- Investigation context
- Identity Portal provides line-level results and leaked-account exports. [11]
- Follow-up
- Paid licenses include alerts; API and export entitlements vary by license. [11]
- 05Best for
Have I Been Pwned
Breach notifications and password screening
Have I Been Pwned is the reference for breach notifications. It shows which breaches an address appears in, offers domain monitoring on subscription and checks password hashes through Pwned Passwords. It does not show the password linked to an account.
- Research scope
- Breach lookups, domain monitoring and a separate Pwned Passwords service. [12]
- Investigation context
- Stealer-log lookups provide email and website relationships, without account-linked passwords. Pwned Passwords checks password hashes separately. [14]
- Follow-up
- Subscription tiers support domain monitoring; stealer-log API access requires an eligible tier. [13]
- 06Best for
Hudson Rock
Infostealer intelligence with device context
Hudson Rock specializes in infostealer data: captured credentials come with device and infection context, and domain searches separate internal from external exposure. Its API covers domain, identity, stealer and file searches.
- Research scope
- Infostealer intelligence includes captured credentials and device context. [17]
- Investigation context
- Domain searches distinguish internal and external exposure and include employee and user categories. [16]
- Follow-up
- API documentation covers domain, identity, stealer and file searches. [15]
LeakCheck alternative for domain and source investigations
Credential lookups with room to investigate
You need domain categories and eligible raw-file or forum searches alongside credential lookups.
Put LeakRadar to work ↗You need LeakCheck's breach lookups, BulkCheck or the search types available in its API.
LeakCheck · Sources and review ↘Compare the data you can actually investigate.
File lines, not a count of unique accounts.
UpdatedPlaintext passwords, with their account context
Inspect the exposed password alongside the account and, for stealer logs, its service URL. When the source includes plaintext, that detail helps your team scope password resets and investigate exposed access.
Compare plans for plaintext access and included unlock points.
Stealer logs
Connect a captured login to its service URL, username and password to understand which access is exposed.
url:user:passCombolists
Find email/password and username/password pairs, including records without a service URL.
email:passuser:passRaw leak files
Search the text of leaked files, database dumps and unstructured records beyond normalized credential fields.
Dark web forums
Search indexed forum posts for mentions of your organization and examine the discussion's source context.
Get notified via Email, Slack, Discord, Telegram or Webhook when new exposed credentials match your monitored domains or email addresses.

Questions before switching
Does LeakRadar have an equivalent of LeakCheck's BulkCheck?
Not as a file upload. To review many accounts of one organization, a domain search returns them together, sorted into employees, third parties and customers, and large exports run as background jobs. For a list of unrelated addresses, you can script lookups through the REST API within your plan's limits.
Can I receive leak alerts in Telegram, as with LeakCheck?
Yes. LeakRadar monitoring sends alerts by Email, Slack, Discord, Telegram or webhook when new exposed credentials match a monitored domain or email address. The number of monitored assets and the available channels depend on your plan.
Does LeakRadar show which website a stolen password was used on?
For stealer logs, yes. Each record keeps the service URL where the credentials were captured, next to the account and, when the source contains it, the plaintext password.
Does LeakRadar offer an API like LeakCheck?
Yes. LeakRadar provides a REST API with token authentication and an official Python client. API access and permitted commercial use depend on your plan and the Terms of Service.
Can I test LeakRadar before leaving LeakCheck?
Yes. A free account lets you explore the search features and monitor your signup email in stealer logs. Run the same authorized queries in both tools, then compare the useful matches rather than the result counts.
