# Free monitoring tools

Free checks for any website. No signup, no account, and each one ends in a plain-language verdict rather than a raw data dump.

## Security

- [SSL/TLS certificate checker](https://ranetrace.com/tools/ssl-checker.md) - Check any site's SSL/TLS certificate, its issuer, and how many days until it expires.
- [Security headers checker](https://ranetrace.com/tools/security-headers.md) - Grade a site's HTTP security headers, from HSTS to Content-Security-Policy.
- [Blocklist checker](https://ranetrace.com/tools/blocklist-checker.md) - Check whether a domain or IP is listed on the major security and spam blocklists.

## DNS & domain

- [DNS lookup](https://ranetrace.com/tools/dns-lookup.md) - Look up the A, AAAA, MX, TXT, and other DNS records behind any domain.
- [Domain & WHOIS lookup](https://ranetrace.com/tools/domain-lookup.md) - See a domain's registrar, registration dates, lock status, and when it expires.

## Availability

- [HTTP status & speed check](https://ranetrace.com/tools/http-status.md) - Check whether a site is up, its HTTP status code, and where its response time goes.

Ranetrace runs these same checks continuously and tells you when something changes: https://ranetrace.com/pricing.md
