Cloudflare Free Tier Limits

Pingflare is designed to stay within Cloudflare free tier limits:

• Workers: 100,000 requests per day
• D1: 100,000 write rows per day, 5 million read rows per day
• Cron Triggers: minimum 1-minute interval

With the default 90-day log retention and automatic cleanup on each cron run, write usage stays bounded proportional to the number of active monitors.
