The Mozilla Monitor alternative for plaintext credentials and domain monitoring
Mozilla Monitor is a free consumer service that tells you whether your email appeared in a known breach, using Have I Been Pwned data. It never shows the password and is limited to your own email addresses. LeakRadar is the professional step up: search the actual plaintext credentials from stealer logs, combolists and dark web dumps across 543B+ leak lines, by email, domain or username, with continuous monitoring, alerts and a REST API.

Mozilla Monitor is a free, privacy-friendly consumer service from the makers of Firefox: enter your email and it tells you, using Have I Been Pwned data, whether it appeared in a known breach. It is a good, trustworthy check for individuals, and it deliberately never shows the leaked password, covers only public breaches, and works one email address at a time. LeakRadar is the professional alternative when a yes or no is not enough: it reveals the actual plaintext credentials across 543B+ leak lines, searchable by email, domain or username, with stealer-log and combolist depth, downloadable raw files, dark web forum search, automatic domain segmentation, five-channel monitoring and a REST API. Search is free, so you can run the same check you would on Monitor, then see the credentials behind it.

Why teams choose LeakRadar over Mozilla Monitor
1
See the actual password, not just a yes or no
Mozilla Monitor confirms your email appeared in a breach but never shows the credential. LeakRadar reveals the real plaintext passwords, usernames and URLs across 543B+ leak lines, so you can see exactly what is exposed and act on it.
2
Beyond your own inbox: domains, usernames and teams
Monitor checks email addresses you own, one person at a time. LeakRadar searches by email, domain or username, segments a domain into employee, customer and third-party exposure, and supports team seats, for security work, not just personal checks.
3
Stealer logs, dark web and a real API
Monitor is built on public-breach data from Have I Been Pwned. LeakRadar adds stealer logs, combolists, downloadable raw files and dark web forum search, with continuous monitoring on five channels and a 30 req/s REST API that Monitor does not offer.

—Frequently asked questions
No. Monitor tells you which breaches an email appeared in and what categories of data were exposed, but it never shows the actual password, and it uses k-anonymity so it never sees your full email either. LeakRadar reveals the real plaintext passwords tied to accounts across 543B+ leak lines once you unlock cleartext on a paid plan.
Show the actual credentials, search by domain and username, and work for organizations. LeakRadar reveals plaintext passwords across 543B+ leak lines, indexes stealer logs and combolists, offers raw file download and dark web forum search, segments a domain into employee/customer/third-party exposure, supports team seats and exposes a REST API, none of which Monitor offers.
Yes. Beyond individual emails, LeakRadar monitors entire domains, automatically segments exposure into employees, customers and third parties, generates PDF incident reports, and alerts on Email, Slack, Discord, Telegram and Webhook. Mozilla Monitor is built for individuals checking their own email addresses.
Search is free on LeakRadar, so you can check exposure at no cost, much like Monitor. You only pay to reveal cleartext at volume and unlock raw files, dark web search, domain monitoring and the API, starting at €29.99/mo. Mozilla Monitor is entirely free but stops at breach alerts for your own email.
Yes, a REST API at 30 requests per second on every plan, with documentation and a Python SDK at docs.leakradar.io. Mozilla Monitor has no public developer API.
The verdict
Mozilla Monitor is a free, privacy-respecting way for individuals to learn whether their email has appeared in a known breach, backed by Have I Been Pwned and a trusted brand. Its limits are by design: it never shows the password, covers only public breaches, and works one personal email at a time. LeakRadar is the professional alternative: it reveals the actual plaintext credentials across 543B+ leak lines, searches by email, domain or username, adds stealer logs, combolists, raw files, dark web forum search, domain segmentation, five-channel monitoring and a REST API. Use Monitor for a free personal check; use LeakRadar when you need to see and act on what actually leaked. Search is free, then from €29.99/mo.
