As answered by people managing Open Devdocs and DNSRobot.net.
DNSRobot.net's answer:
Next.js, React, TypeScript, Node.js, Tailwind CSS, and shadcn/ui. DNS queries use Node.js native dns module, Cloudflare DNS-over-HTTPS for DNSSEC, and RDAP for WHOIS data. Deployed on Nginx with PM2 process management.
DNSRobot.net's answer:
DNSRobot.net's answer:
DNS Robot combines 53 DNS, domain, email security, SSL, and network tools in one place — completely free with no signup, no API key, and no rate limits. Most competitors offer 10-15 tools and gate features behind paid plans. DNS Robot also supports 12 languages and provides a public API that AI agents can use directly.
DNSRobot.net's answer:
Unlike MXToolbox or DNSChecker, DNS Robot gives you everything for free — no account walls, no premium tiers, no captchas. It runs 53 tools including unique ones like Domain Health Check (scores your domain 0-100 across 11 checks in one click), auto-detecting DKIM selector from 65+ common names, and IP blacklist scanning across 47 DNSBL engines simultaneously.
DNSRobot.net's answer:
Web developers, system administrators, DevOps engineers, email marketers, and security researchers who need quick, reliable DNS and network diagnostics without creating accounts or paying for subscriptions.
DNSRobot.net's answer:
DNS Robot started from frustration with existing DNS tools — they were either slow, cluttered with ads, or locked useful features behind paywalls. We built a clean, fast, ad-light platform that puts all 53 tools one click away. It's built with Next.js and runs real-time queries using native DNS resolution, RDAP, and Certificate Transparency logs.
