staygreen.io：免费应用监控服务上线，含 MCP server
面向独立开发者的免费监控服务，支持 uptime、SSL、DNS、Stripe webhook、Supabase 检查，并提供给 AI agent 用的 MCP server。
Paid app monitoring services were driving me crazy: > $30/mo for a custom status page domain? > $34/mo for webhooks alerts > $330/mo for white-label > Unable to monitor Stripe or Supabase So, I just launched free staygreen[.]io I built for myself. 100% free (lifetime): - Uptime, SSL, DNS, TCP and heartbeat monitors - Checks that read what your app returns - Stripe webhook and Supabase project checks - Email, Telegram, Slack, Discord and webhook alerts - A status page on your own domain - MCP server for your AI agents - 1 app, 50 monitors and 5 heartbeats - HTTP checks every 3 min from SF & Toronto - Commercial use Just give it your app URL, it will suggest all monitors, thumbnails, branding color, etc. Feedback: https://github.com/phuryn/staygreen 🙏 P.S. I'm open sourcing it after hitting 500 users or 1,000 GitHub stars
