CK Cyber Playground
Build Anything
A playground for us to build anything we want: tools, experiments, games, timers, demos, and whatever comes next.
Boxing Timer Benchmark
Run boxing, sparring, and conditioning intervals while comparing total work, rest, density, and session duration.
World Clock Converter
Track team time zones and convert meeting times across North America, Europe, and APAC.
SafeShare Photo
Check photo metadata, remove private data locally in the browser, verify the result, and download a clean copy.
QR Safety Checker
Decode a QR code locally, review the full destination, and understand warning signs before opening a link.
Personal Exposure Finder
Type a name and get a robust Google dorking matrix for checking public profiles, documents, organization pages, URLs, and recent mentions.
Password Pattern Lab
Build a small defensive training dictionary sample to understand predictable password patterns and safer password habits.
URL Snapshot Viewer
Review a URL locally, search existing urlscan.io scans, or request a no-key screenshot preview through mShots.
Domain Exposure Audit
Create scoped Google dorks for owned-domain public admin, credential, debug, backup, document, and exploit-reference exposure.
Certificate Checker
Check a public website TLS certificate for hostname match, issuer, expiration, chain count, fingerprint, and handshake metadata.
Domain Registration Lookup
Look up public RDAP registration details, domain age, registrar, expiration, nameservers, redaction, and status codes.
Browser Permission Checker
Check current-site permissions in the browser, test popup behavior, and see browser-specific steps for turning permissions off.
Each new idea can live here as its own page.
