Why developers switch from UptimeRobot

10x better value

UptimeRobot charges $7/mo for 10 monitors. CronAlert gives you 100 monitors for $5/mo. That's $0.05 per monitor vs $0.70 — a 14x difference.

More alerts on free

UptimeRobot locks Slack, webhooks, and SSL monitoring behind paid plans. CronAlert includes all alert channels and SSL monitoring on the free tier.

Faster free checks

UptimeRobot's free tier checks every 5 minutes. CronAlert checks every 3 minutes — you'll know about issues 40% sooner without paying a cent.

AI-native with MCP

CronAlert is the only monitoring tool with an MCP server. Manage monitors, check status, and investigate incidents directly from Claude, Cursor, or any AI assistant.

That's it. Your monitors start checking immediately.
