What we build
- Domain and DNS tooling for lookup, security signals, and propagation checks.
- SSL and certificate checks for trust, expiry, and connection details.
- IP utilities and learning references for network context.
- Text, encoding, and formatting utilities for daily tasks.
Principles
- Accuracy first: highlight the strongest signal, not the most noise.
- Clear output: results should be easy to read and act on.
- Practical defaults: sane thresholds and explanations without jargon.
- Consistent UI: familiar layouts across tools for faster use.
Who it is for
CuscusLab is built to serve a wide audience: developers, IT staff, SEO teams, support engineers, and anyone who needs fast answers about domains, security posture, or data formatting.
Data and limitations
CuscusLab combines local processing with upstream DNS and registry responses. Results can vary by region, resolver, and timing. When data is ambiguous, we surface warnings instead of hiding uncertainty.
