Get A+ to F grades with plain-English explanations. Built for indie builders who ship fast but want to stay secure.

2. **Secret Scanner** - Scans your website's public JavaScript files for exposed API keys, tokens, and credentials. Detects AWS keys, Stripe tokens, Google API keys, GitHub tokens, Firebase configs, OpenAI tokens, and 20+ other patterns. If hackers can find it, we show you first.

3. **Ghost API Hunter** - Probes for accidentally exposed API documentation like /swagger, /api-docs, /graphql, /.env files, and debug endpoints. Scans your main domain plus common subdomains (api.*, backend.*, dev.*, staging.*, admin.*).

4. **SSL Certificate Checker** - Verify SSL/TLS certificates for any domain. Check certificate validity, expiration dates, issuer details, and certificate chain status.

5. **DNS Health Check** - Analyze any domain's DNS configuration including SPF, DKIM, DMARC, MX records, DNSSEC, and CAA records. Essential for email deliverability and security verification.

6. **Blacklist/Reputation Check** - Check if a domain is listed on public spam blacklists (Spamhaus, SURBL, URIBL, SpamCop, Barracuda).

7. **Free Security Alerts (Preview)** - Opt-in, low-frequency email alerts for one domain. Monitors SSL expiry, DNS health, security headers, reputation, exposed secrets, and leaked APIs. No account required.
