# Domain Lab

> Domain Lab (domainlab.app) is an AI-powered domain monitoring service. It tracks domain expiration (WHOIS/RDAP), DNS record changes with full history and diffs, and SSL certificate health across all registrars — then explains every change in plain English with AI analysis and alerts you via email, Slack, Pushover, or webhooks.

Domain Lab re-scans every domain daily — including on the free plan — where some domain tools check registration data only weekly. It is built for developers, agencies, and domain owners who manage domains across multiple registrars and want one dashboard with intelligent alerts.

## Key features

- Domain expiration monitoring via WHOIS and RDAP across TLDs, with smart renewal alerts
- DNS change detection: every record change is stored as a diff with full history
- SSL certificate monitoring: expiry, issuer, and configuration changes
- AI-powered analysis: plain-English explanations of what each domain, DNS, or SSL change means
- Event feed of all detected changes per domain
- Custom notification rules per domain and event type
- Alert channels: email, Slack, Pushover, and custom webhooks
- Connect Claude, ChatGPT and other AI assistants to your account (MCP server); REST API with API keys for automation (works with Zapier, n8n, Lindy)

## Pricing

- Base plan: free — monitor 1 domain, daily checks, DNS comparison included, no credit card required
- Pro plan: $9/month — monitor up to 100 domains, daily checks, AI reviews, registrar sync (auto-import from Cloudflare and Porkbun), full REST API access, and AI agent & automation integrations (Zapier, n8n, Lindy)
