Hey Product Hunt! 👋 I built Expert Web Tools because I was tired of pasting sensitive data — JWTs, JSON payloads, cURL commands, hashes — into random online tools and hoping for the best. Every single tool on this site runs 100% in your browser via JavaScript and WebAssembly. Nothing is sent to a server. No accounts. No tracking. No logs. Ever. Some tools I'm especially proud of: 🔧 WAF & Rewrite Rule Builder — visually generate Cloudflare, NGINX, Apache & AWS WAF rules 🐳 Visual Dockerfile Builder — multi-stage, non-root, secure Dockerfiles in seconds 🔐 CSP Validator — AI-assisted Content Security Policy analysis and secure baseline generator ⚡ cURL to Code Converter — paste any cURL command, get Python / JS / PHP / Go output instantly 🔍 DNS Lookup with SPF/DMARC — no-fluff authoritative record checker I'd love to hear which tools you find useful — and what's missing. What would you add? Happy to answer any questions below 👇
