CronSignal

Hey PH! I'm MAK, a PM who spent years working on developer tools. One pattern I kept seeing: simple cron job failures causing outsized pain. A backup script silently stops running, a sync job breaks, and nobody knows until it's too late. CronSignal is my attempt at building small, focused observability tools for indie developers and small teams. One problem, solved well, with flat pricing so you never think twice about adding another monitor. How it works: add a curl to your crontab, we alert you if it doesn't ping on schedule. That's it. What you get: 1. $5/month flat - unlimited monitors, no per-job fees 2. Email, Slack, Telegram, Discord and Webhook alerts - including recovery notifications 3. MCP server - integrate with Claude, Cursor, or any AI coding assistant to manage monitors programmatically This is the first product in what I hope becomes a suite of simple, dev-focused monitoring tools (UptimeSignal is next). Would love feedback from the PH community. Happy to answer questions!
