Frequently asked questions

Is sunwatch a free uptime monitor?

Yes — start with 3 monitors at no cost, with 1-minute checks and webhook alerts. Extra monitors are $1/monitor/month.

What is a crypto-paid uptime monitor?

A crypto-paid uptime monitor lets you pay for monitoring with cryptocurrency instead of a card or subscription. sunwatch accepts USDC on Base, so you can add monitors wallet-to-wallet without KYC or recurring billing.

Do I need an account or KYC?

No account, no email, no identity verification. Add a URL and webhook and you're monitoring in seconds.

How do webhook alerts work?

When your site's state changes, sunwatch POSTs a JSON payload to your webhook. Route it to Slack, Discord, PagerDuty, or any endpoint you control.

What crypto does sunwatch accept?

Payments are handled with Base Pay using USDC on Base. No subscription lock-in — pay only for the monitors you want.
