Cloudflare Workers Free, 100,000 free requests per day

Free limits: Dynamic requests are limited to 100,000 per day, with 10 ms of CPU time per invocation, the time actually used for computation. Static asset requests, such as images and files, are free and have no request limit. However, Worker execution paths and cache billing conditions apply separately. CPU limits and paid costs arising from external API usage are separate.

対象: Both new and existing accounts can use the default Free plan.

Card registration: You can get started without a card.

When used in Korea: This is a globally distributed service, and a network point of presence in Seoul has been confirmed. It does not guarantee that data is stored and processed only in Korea.

When not in use: It runs when a request comes in, rather than keeping a virtual machine (VM) running continuously. The documentation I checked does not specify a fixed deletion period for inactivity.

If you exceed the limit: Exceeding the daily limit on the Free plan results in an error. Switching to a paid plan incurs a minimum charge of $5 per month, plus overage fees.

Commercial use: I found no restriction in the terms I reviewed requiring use to be personal and non-commercial only. However, there are usage restrictions, including a ban on collecting or processing payment card information on free web properties.

Usage period: This is not a limited-time trial.
