Is there an alternative to Leakdom.com?

I’m not sure which specific features of Leakdom.com you want to replace (data breaches, leaked databases, searchable leak archives, news about leaks, etc.). Here are several alternatives grouped by common purposes—pick the category that matches what you used Leakdom for.

If you tracked leaked data / searchable breach dumps

• Have I Been Pwned (haveibeenpwned.com) — search email addresses and see which breaches included them (focused on notifying individuals, not hosting raw dumps).
• Dehashed (dehashed.com) — searchable breach database for emails, usernames, IPs; paid tiers for full access.
• IntelX (intelx.io) — searchable archive of leaked data, paste sites, and darknet content (paid).
• BreachDirectory (breachdirectory.org) — searchable leaked credentials (availability varies).

If you followed news and analysis about data breaches

• Krebs on Security (krebsonsecurity.com) — investigative reporting on breaches and security incidents.
• The Hacker News (thehackernews.com) — frequent breach coverage and commentary.
• DataBreaches.net — reporting and tracking of breaches and extortion.

If you wanted aggregations of pastebin/darknet leaks

• Pastebin search engines and archives (various; availability changes).
• Dark web monitoring services (commercial): Digital Shadows, Recorded Future, Cybersixgill — they provide monitoring & alerts.

If your interest was for verifying leaked passwords locally

• Have I Been Pwned's Pwned Passwords (pwnedpasswords.com) — downloadable password hashes you can check locally.
• Hashes.org and other public password-cracking repositories (use responsibly and legally).

Safety/legal note

• Accessing or downloading raw stolen data can be illegal and unethical. Prefer reputable services that provide notification and aggregation without redistributing stolen content, and consult legal guidance if you’re unsure.

If you tell me which Leakdom feature you used (searching emails, browsing dumps, news, monitoring), I can recommend the best specific alternative and free vs paid options.
