shadom.co vs Free Domain Alerts
Both track domain expiration for free. Here is where the limits and features differ, sourced from each service's own pages.
What Free Domain Alerts does
Free Domain Alerts tracks domain and SSL certificate expiration and emails you before they lapse. Its own pricing page states 20 domains are free, with paid plans for higher limits. It also adds upcoming expirations to your calendar, lets you invite a team, and exports data as CSV, Excel, or PDF. It is positioned as a simplified version of the same makers' bigger tool, Little Warden.
What shadom.co does
shadom.co monitors up to 100 domains free, with email, push, and webhook alerts for expiration, registrar and nameserver changes, and status transitions. It calculates a predicted drop date per domain using TLD-specific lifecycle timing (grace, redemption, pending delete), not just the expiry date, and exposes the same data through a REST API and an MCP server for AI agents.
Where they differ
If SSL certificate expiration or calendar sync matters to you, Free Domain Alerts covers that and shadom.co currently does not. If you need more than 20 domains free, want push or webhook alerts, need a predicted drop date rather than just the expiry date, or want API/MCP access, shadom.co covers those and Free Domain Alerts' public pages do not describe them.
