# Cloudflare Workers

Canonical: https://inetgeek.com/hosting/cloudflare-workers/

Serverless runtime that executes JavaScript, TypeScript, Python and WebAssembly isolates in every Cloudflare data centre, with KV, queues and Durable Objects alongside.

## Who it suits

Code that should run in every Cloudflare data centre rather than one chosen region, where 10 ms of free CPU per request is enough to start and a $5 account minimum then covers Workers, KV, Hyperdrive and Durable Objects together.

Consider something else if The work is CPU-bound or long-running: the free plan allows 10 ms of CPU per HTTP request and stops at 100,000 requests a day, and the paid plan defaults to 30 seconds rather than the 5-minute ceiling.

## What the documentation says

### Pricing

- Free tier: Yes ([source](https://developers.cloudflare.com/workers/platform/pricing/), read 2026-09-14)
- What the free plan includes: 100,000 requests a day on the free plan, resetting at midnight UTC; a Worker over the limit returns Cloudflare error 1027. ([source](https://developers.cloudflare.com/workers/platform/limits/), read 2026-09-14)
- Entry paid plan: $5/month minimum charge for an account on the Workers Paid plan, which covers Workers, Pages Functions, Workers KV, Hyperdrive and Durable Objects usage. ([source](https://developers.cloudflare.com/workers/platform/pricing/), read 2026-09-14)

### Execution

- CPU time limit: 10 ms of CPU per HTTP request on the free plan; up to 5 minutes on paid, defaulting to 30 seconds. Time spent waiting on network requests does not count. ([source](https://developers.cloudflare.com/workers/platform/limits/), read 2026-09-14)

### Infrastructure

- Regions: No region selection. A Worker runs in the data centre closest to the request; Smart Placement can instead pin it near a named cloud region, host or hostname. ([source](https://developers.cloudflare.com/workers/configuration/smart-placement/), read 2026-09-14)
- Uptime SLA: 99.99% monthly, in a dedicated Workers SLA that says it applies to use of Workers only and names no plan tier. Cloudflare's separate application-services plan table shows an uptime SLA on Business and Enterprise only. ([source](https://www.cloudflare.com/workers-service-level-agreement/), read 2026-09-14)

### Support

- Support on entry paid plan: Community forum and Discord on every plan, with Discord named as the Developer Platform channel. Opening a support case needs Pro or above — Free is limited to billing, account and registrar issues. Live chat starts at Business, emergency phone at Enterprise. ([source](https://developers.cloudflare.com/support/contacting-cloudflare-support/), read 2026-09-14)
- Response time commitment: None on the Workers Paid plan: Cloudflare says pay-as-you-go and Free customers get no SLA and are answered in the order received. Priority response times are sold as the Premium and Enterprise SLAs — 1 hour and 2 hours for an urgent P1.
