Frequently asked questions

How are arrays compared?

By default, arrays are compared by position (index 0 vs index 0, etc.). Enable "Ignore Array Order" to sort arrays before comparing, which treats [1,2,3] and [3,1,2] as identical.

What is JSONPath notation?

JSONPath uses dot notation to describe the location of a value. For example, $.user.name means the "name" field inside the "user" object at the root level.

Can I compare deeply nested objects?

Yes. The diff algorithm recursively walks both JSON trees and detects changes at any depth. Each change includes the full path from root to the changed field.

Free SSL Certificate Checker

Enter a domain to inspect its SSL/TLS certificate. You'll see the issuer, validity dates, days until expiry, protocol version, and whether the certificate chain is healthy. Useful for catching expiring certificates before they cause browser warnings.

Security Headers Checker

Paste a URL to analyze its HTTP security headers. The tool checks for Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and other headers that protect against common web attacks. You'll get a grade and a list of missing protections.

Free Email Validator

Enter an email address to validate it. The tool checks format syntax, resolves MX records to verify the domain accepts mail, detects disposable email services (like Mailinator), and flags role-based addresses (like info@ or admin@). Useful for cleaning mailing lists or validating form submissions.

Email Authentication Checker (SPF, DKIM, DMARC)

Enter a domain to check its email authentication configuration. The tool validates SPF records (who can send on your behalf), DKIM records (email signatures), and DMARC policies (what to do with unauthenticated mail). Misconfigured authentication is the top reason emails land in spam.
