Every tool on this site
44 tools are live and 0 are on the build plan. Press / or Cmd+K anywhere to search them. This page is the crawlable version of that palette, and it stays honest about what is not built yet.
Your IP
- /Your public IP address, rendered at the edge with no client fetch, plus approximate location, ISP, ASN and connection type.
- /ipYour public IP as text/plain with a trailing newline. Built for curl, scripts and CI.

- /browser-infoWhat your browser reveals: engine, OS, screen, languages, timezone and privacy signals.
- /http-headersThe HTTP headers your browser actually sent, with a one-line explanation for each.
Privacy

- /dns-lookupA, AAAA, MX, TXT, NS, SOA, CAA, SRV, PTR, DNSKEY and DS from two resolvers in parallel.
- /whois-lookupRegistrar, dates, nameservers, status and abuse contact, normalised from RDAP with a WHOIS fallback.
- /reverse-dnsPTR records plus a forward-confirmed check that tells you whether the name is trustworthy.
- /mx-lookupMail records with an SPF lookup-count check and DMARC policy parsing.
- /ssl-checkerSubject, SANs, issuer, validity, days left, key type and chain for any HTTPS host.
- /blacklist-checkWhether an address is listed on a curated set of attributed public blocklists.
- /asnA curated set of autonomous systems: the clouds, CDNs, carriers and ISPs most public addresses belong to.
Diagnostics
- /port-checkTCP connect check against curated ports on your own address, or one port you enter.
- /ping-testRound-trip time from three regions with min, average, max and loss.
- /tracerouteHop-by-hop path from three regions with PTR and approximate geography per hop.
- /speed-testDownload, upload, latency and jitter measured against edge and object storage.
- /multi-vantageWhat our edge sees compared with probes in the US and the EU.
- /reachability-checkWhether your browser can reach a short list of major endpoints, measured client side.
Utilities
- /subnet-calculatorIPv4 and IPv6 CIDR maths: network, broadcast, range, host count, mask and wildcard.
- /mac-lookupVendor for any MAC address or OUI prefix, from a bundled IEEE table.
- /ip-converterDotted quad, decimal, hex and binary, plus IPv6 compress and expand.
- /user-agent-parserPaste any user agent string and read the browser, engine, OS and device it claims.

- /widgetA small card showing a visitor IP and country, embeddable with one tag.
Learn
