About NosHost

NosHost is a free troubleshooting toolkit for people who run websites. It lets you look up DNS records, check email authentication (SPF, DKIM and DMARC), inspect SSL certificates and trace redirects, then explains what each result means and what to investigate next. Configuration helpers cover cron schedules, robots.txt and redirect rules, and guides walk through common problems such as delayed DNS changes and redirect loops. The public tools need no account, though server checks have limits and may reuse clearly labelled recent results.

What can it do?

  • DNS record lookup
  • SPF, DKIM and DMARC email authentication checks
  • SSL certificate inspection
  • Redirect tracing
  • Cron, robots.txt and redirect-rule helpers
  • Guides for common website problems

What does free actually mean?

Public tools are free with no account required. Server checks have limits and may reuse clearly labelled recent results. It covers basic checks, not a full paid monitoring suite.
