About Domain Inspector

Domain Inspector is an Internet security and domain diagnostics toolkit for Ubuntu Touch. It is vibe coded using AI.

Enter a domain name and inspect its public DNS, website, mail and routing configuration directly from your phone.

Checks include:
- IPv4 and IPv6
- DNSSEC validation
- NS, MX and TXT records
- HTTPS/TLS and certificate validity
- HTTP to HTTPS redirects
- HSTS and Content-Security-Policy
- CAA
- security.txt
- SPF and DMARC
- MTA-STS and TLS-RPT
- SMTP STARTTLS
- DANE/TLSA
- RPKI route authorisation

The feature set is inspired by modern Internet standards covered by Internet.nl. Domain Inspector is independently implemented and is not affiliated with Internet.nl. It does not send domains to Internet.nl and does not reproduce Internet.nl's scoring system.

RPKI prefix/origin information uses the documented public RIPEstat Data API from RIPE NCC.

The app performs read-only standards and configuration checks. It is not a vulnerability scanner and does not attempt exploitation.

Privacy:
- no advertising
- no analytics or tracking
- no account required
- DNS uses your configured resolver
- web/mail checks connect directly to the inspected services
