VectorDNS

DNS lookup, WHOIS, and domain monitoring tool. Search nameservers, check domain availability, and track DNS record changes over time.

Features

DNS Record Lookup — Query A, AAAA, MX, TXT, NS, CNAME, SOA, CAA, and SRV records for any domain
WHOIS Lookup — View registrar, registration/expiration dates, nameservers, and domain status
Domain Availability — Check if a domain is registered or available via IANA RDAP
Domain Monitoring — Save domains to a dashboard, track DNS changes over time, get alerts when records change
Change Detection — Daily automated re-checks with visual diffs showing what changed
Notifications — In-app notification feed + email alerts via Resend
Dark Mode — Dark theme by default with light mode toggle

DNS API: Go microservice on VPS (miekg/dns — direct UDP/TCP resolution, DNSSEC, propagation checks)
Deployment: Vercel (frontend) + VPS (Go DNS API)
Package Manager: Bun

Getting Started

Prerequisites

Bun >= 1.3
A Supabase project (free tier works)
(Optional) Resend API key for email alerts

Setup

# Clone and install
git clone https://github.com/DevVoxel/VectorDNS.git
cd vectordns
bun install

# Configure environment
cp .env.local.example .env.local
# Fill in your Supabase URL, anon key, and other values

# Run database migrations
# (see supabase/migrations/ once they exist)

# Start dev server
bun dev

Open http://localhost:3000 to see the app.

Environment Variables

Variable	Required	Description
`NEXT_PUBLIC_SUPABASE_URL`	Yes	Your Supabase project URL
`NEXT_PUBLIC_SUPABASE_ANON_KEY`	Yes	Supabase anonymous/public key
`SUPABASE_SERVICE_ROLE_KEY`	Yes	Service role key (for cron jobs)
`CRON_SECRET`	Yes	Secret to authenticate Vercel cron requests
`RESEND_API_KEY`	No	Resend API key for email notifications

Architecture

VectorDNS uses a hybrid architecture: Next.js on Vercel for the frontend, and a Go microservice on a VPS for DNS resolution and monitoring. See docs/architecture.md for details and docs/api-spec.md for the Go API spec.
