The technical memory of the internet,written by a crawler
VikiTronBot continuously observes how the public internet is built, secured and changing — and opens that record as free tools to explore it and a public API to build on it.
Free Webmaster Tools
Every tool here is a UI over the same live dataset our crawler builds: DNS records, TLS certificates, IP metadata, subdomains, robots.txt.
DNS Records Checker
Instant DNS record check including TTL, DNSSEC and configuration errors.
DNS History
Explore historical DNS records and track domain changes over time.
DNS Explorer
Full-text search and filtering in our DNS index across domains.
Subdomain Finder
Discover subdomains from DNS, certificates and public sources.
SSL Certificate Checker
Verify TLS certificate details, chain, expiration and hostname match.
Robots.txt Checker
Download and verify robots.txt, validate syntax and test user-agent rules.
IP Lookup
WHOIS, reverse DNS, geolocation, ASN and domains hosted on IP.
My IP
Your public IP address, hostname, protocol and network info.
Tor IP List
Complete list of Tor exit nodes and relays with geolocation data.
What “memory” actually means
Most tools ask a single question, then forget the answer. VikiTron keeps the record.
Continuous, not one-shot
VikiTronBot crawls around the clock and versions what it sees. Look up not just the current DNS record, but every change over time.
Respectful by design
Honors robots.txt, adaptive rate limiting, transparent user-agent and contact. Full crawling policy at /bot.
One dataset, two surfaces
Every free tool here calls the same public JSON API. What you can click, you can also script.
Beyond DNS
TLS handshake, Certificate Transparency, reverse DNS, ASN, geolocation and Tor exit-node list — all in one index.
Who uses the record
The same public dataset serves very different jobs.
Webmasters
Debug DNS, verify TLS renewals, audit robots.txt, discover forgotten subdomains.
Security & OSINT
Certificate Transparency, historical DNS, reverse DNS on any IP, live Tor exit-node list.
Developers & SREs
Every lookup here has a JSON endpoint. Wire it into monitoring, CI checks or your own dashboards.
About VikiTron
A public-internet observatory maintained by BizKitHub. VikiTronBot crawls the technical surface of the web — DNS, TLS, IPs, subdomains — and keeps a historical record of how it changes.
The name goes back to 2012. Today it's a crawler-first data project — free tools for anyone, public JSON API for anything you want to build on top.
