All Tools
Every tool below is free, requires no account, and runs real checks against named public services. Each result carries a source label — browser, API, or target server — so you always know where a number came from. Tools are grouped into categories and are also explained in the Guides.
Network Tools
Understand how a device or a domain is seen on the internet.
What Is My IP
See your public IP address, its approximate location, ISP and ASN — detected live from your browser.
Open ToolIP Lookup
Look up location, ISP, ASN and timezone details for any public IPv4 or IPv6 address.
Open ToolDNS Lookup
A, AAAA, CNAME, MX, NS, TXT, CAA and SOA records from Google Public DNS, with real TTLs.
Open ToolHTTP Status Checker
Real HTTP status codes, redirect chains and response headers — clearly labeled server-side requests.
Open ToolWebsite Analysis & SEO
Inspect what a website actually serves — tags, HTTPS setup, certificates and responses.
SEO Checker
On-page checks on live HTML: title, meta description, canonical, headings, robots.txt, sitemap, Open Graph, images and HTTPS.
Open ToolSSL / HTTPS Checker
HTTPS availability, HTTP-to-HTTPS redirects, certificates from transparency logs, security headers and mixed content.
Open ToolPerformance Tools
Measure real performance — of your connection and of the sites you rely on.
SEO & Crawl Tools
Files that decide how a crawler reads your site: what it is allowed to fetch, and how it discovers your pages.
Robots.txt Checker
Read every user-agent group and directive, and get the specific line to change when the site is blocked or a rule is ignored.
Open ToolSitemap Checker
Validate XML, URL counts, lastmod formats, duplicates and the sitemap namespace, for a urlset or a sitemap index.
Open ToolAdSense Readiness Checker
Crawl a site and score it across six categories — content, trust, navigation, crawlability, policy risk and performance — with every deduction explained and a repair plan for each one.
Open ToolSocial Media Tools
Run giveaways and pick winners fairly from social media comments using official APIs.
Random Comment Picker
Pick winners fairly from YouTube, Facebook, and Instagram comments. Transparent, auditable random selection using official APIs. Supports filtering, deduplication, and export.
Open ToolHow these tools stay honest
Named public services only
Every tool uses keyless public APIs and services that are named on the page and in the Privacy Policy: ipify, ipwho.is, Google Public DNS (dns.google), microLink, hackertarget, crt.sh, public CORS relays and Cloudflare's speed-test network. There are no hidden endpoints and no private keys in the code.
Limitations are disclosed
When a browser or API cannot measure something (for example the live TLS version or Core Web Vitals of another site), the tool reports “Not available in this test” instead of guessing. See the Disclaimer for the full statement.
