📚 Domainstack - Domain Intelligence Tool

Domainstack is an all‑in‑one app for exploring domain names. Search any domain (e.g., github.com) and get instant insights including WHOIS/RDAP lookups, DNS records, SSL certificates, HTTP headers, hosting details, geolocation, and SEO signals.

🚀 Features

• Instant domain reports: Registration, DNS, certificates, HTTP headers, hosting & email, and geolocation.
• SEO insights: Extract titles, meta tags, social previews, canonical data, and robots.txt signals.
• Screenshots & favicons: Server-side screenshots and favicon extraction, cached in Cloudflare R2.
• Fast, private, no sign-up: Live fetches with smart caching.
• Reliable data pipeline: Postgres persistence (Drizzle), background revalidation (Inngest), and Redis for short-lived caching/locks.
