Accounts using the Workers free tier are limited to a maximum of 100,000 requests per day, with a burst rate limit of 1000 requests per 10 minutes. This limit applies at the account level, meaning that requests on your
workers.dev subdomain count toward the same limit as your zoned domains. Visitors who run into the rate limit will be served a Cloudflare 1015 error page, however if you are calling your script programmatically, you can detect the rate limit page and handle it yourself by looking for HTTP status code 429. Upgrading to a paid plan will automatically lift this limit.
感觉自己用用可以,但是做公开服务很容易被搞啊==隔 10 分钟来 1000 次请求就炸了
