Edge Computing and Developer Platform
Cloudflare's developer platform lets you build and deploy applications at the edge — running your code in 330+ cities worldwide, milliseconds from your users. No servers to manage, no containers to orchestrate, no cold starts to worry about.
What's Free
Workers (100k requests/day), Pages (unlimited sites), KV (limited reads/writes), D1 (5M rows read/day), Durable Objects (limited), Queues (limited), Secrets Store, and Version Management are all available on the free plan.
