Compare LeakRadar and LeakCheck for exposed credentials, monitoring and API workflows. Review source context and plan access before choosing.

Credential lookups with room to investigate

Our assessment uses public product documentation. It is not an independent benchmark of coverage or detection speed.

## Choose LeakRadar when

You need domain categories and eligible raw-file or forum searches alongside credential lookups.

## When to consider the other product

You need LeakCheck's breach lookups, BulkCheck or the search types available in its API.

## Compare the work you can do

| What matters | LeakRadar | LeakCheck |
|---|---|---|
| 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. | Breach and infostealer data, with search types that vary by 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. | Pro API supports several lookup types and detailed results on eligible plans. |
| 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. | Monitoring and Telegram alerts, plus BulkCheck for multiple lookups. |
Features can depend on the subscription and dataset. A missing mention in public documentation is not evidence that a feature is unavailable.

## Access and pricing

## Plaintext 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.

## Access that fits your work

Start with a free account, then choose the plan that fits your datasets, monitoring, exports and team.

Get notified via Email, Slack, Discord, Telegram or Webhook when new exposed credentials match your monitored domains or email addresses.
