**Only pay for what you use**

Pay only for execution time ([CPU time](https://developers.cloudflare.com/workers/platform/limits/#cpu-time)), not idle time spent waiting on I/O.

**Near your users, or your data**

Deploy once, run in Cloudflare's 335+ cities by default, or use [Smart Placement](https://developers.cloudflare.com/pages/functions/smart-placement/) to run near your data, to minimize end-to-end latency.

**No cold starts**

Don't keep users waiting, or spend your time on prewarming rube-goldberg machines.

**Infinite concurrency without the markup**

No need to pay for pre-provisioned concurrency. Just scale up based on demand on your big launch days, no matter how many concurrent users you get.

**First-class local development**

Workers allows you to fully test your changes locally and allow you to get in the flow, ahead of pushing your changes with [workerd](https://github.com/cloudflare/workerd), our open-source runtime.

**Write in JS, TS, Python or Rust**

Choose from a template in your language to kickstart building an app.

### Serverless architecture, from the ground up: Isolates vs. Containers

Workers are built on unique architecture called isolates. Isolates are an order of magnitude more lightweight, which means they can easily and quickly scale up and down to meet your needs.

User code

Process overhead

Build scalable APIs

Handle billions of requests with automatic scaling and global deployment. No load balancers, no capacity planning, no regional configuration.

Deploy complete web applications

Ship React, Vue, or Next.js apps integrated backend logic, databases, and storage. Full-stack development without infrastructure management.

Run serverless functions at the edge

Handle authentication, rate limiting, routing, caching logic near your users. Reduce latency and reduce load on your server by offloading processing to Workers.

Run business logic and background jobs

Handle webhooks, process data, and run scheduled tasks with built-in Queues, Workflows, and Cron Triggers. Reliable automation without server babysitting.

### Hello World to full-stack on a single integrated platform

Go beyond hello world by connecting to any resources you need — database, storage, browser rendering, images and more with a simple binding.

###### Deploy with confidence, even on Fridays

Go from localhost to global in seconds

###### ...or by clicking merge

Cloudflare Workers connects directly to your Git repository, allowing you to deploy however, whenever you want

### Go fast, or slow

Workers enables you to instantly deploy to all 330+ cities, or gradually roll out changes to a percentage of your users. If errors spike up, roll back when you need.

#### Cloudflare's toolkit is accelerating that movement even faster. Their clear documentation, purpose-built tools, and developer-first platform helped Intercom go from concept to production in under a day. "

### Powerful primitives, seamlessly integrated

##### Built on systems powering 20% of the Internet, Workers run on the same infrastructure Cloudflare uses to build Cloudflare. Enterprise-grade reliability, security, and performance are standard.
