Free tools for the web-curious.

Handy utilities we use every day, free for everyone. Look up DNS records, trace redirects, inspect JSON and more — most of them run entirely in your browser.

DNS Lookup

Query A, AAAA, MX, TXT, NS and CNAME records for any domain — straight from your browser.

Reverse IP Lookup

Find the PTR (reverse DNS) hostname behind any IPv4 or IPv6 address.

HTTP Status Code Checker

Check the HTTP response status of any URL and follow its full redirect chain.

Open JSON

Validate, pretty-print and explore JSON in a collapsible tree — nothing leaves your browser.
