The Best Breach & Leak Check Tools in 2026
A data breach search tool tells you whether an email, username or password has leaked — and where. We compared the most widely used breach and credential search engines on the things that actually matter: whether there's a free tier, the cheapest paid entry, whether they reveal passwords, API access, and how many records they index. Every figure below was checked on each provider's own site.
