Free technical checks
Small diagnostic tools for obvious DNS, deliverability and integration problems. They are meant to reduce guesswork quickly, not to replace a full review when production systems are already causing business issues.
Free SPF/DMARC Validator
Live nowQuick check for SPF, DMARC and basic mail-routing signals before deeper DNS or deliverability cleanup.
Stripe Webhook Tester
Live nowSimulate a Stripe-style webhook delivery to see whether a public endpoint responds cleanly or fails before production payments depend on it.
Hosting & CMS Architecture Detector
Live nowInspect a public domain for obvious hosting, framework and CMS signals before you inherit an unclear stack or migration risk.
Misconfiguration & Vulnerability Scanner
Live nowQuick public checks for missing security headers, exposed WordPress endpoints and obvious file exposure mistakes on a live domain.
Need a full fix instead of a quick scan?
If the issue is already affecting enquiries, invoices, payment flow or customer communication, the right next step is usually direct troubleshooting rather than more self-service testing.
