# Platforms

> Make your SaaS instantly extensible—no extra infra, no extra risk.

Cloudflare turns any software product into a secure, multi-tenant platform. Let customers run their own code, store data, and expose APIs—directly on Cloudflare's global edge—while you stay out of the infrastructure business.

## Benefits

### Run untrusted code, safely

Each customer's logic lives in its own sandboxed Worker—isolated, metered, and shielded from your core.

### The full per-tenant platform

Create per-tenant, or project Workers, D1 databases, KV namespaces, R2 buckets, and vanity domains. Everything you need in one place.

### Zero infrastructure overhead

No clusters to reserve, no cold starts to dread. Pay only for the CPU cycles your customers actually use.

## Features

### Workers for Platforms

A safe, isolated compute runtime where each customer runs code as part of your app.

### Fine-grained ingress/egress controls

Dispatch traffic to customer Workers, set per-tenant limits, and meter every request for billing.

### Actor-model Durable Objects

Stateful primitives for carts, chat rooms, or per-store config—co-located with users for <50 ms access.

### First-class data bindings

Expose D1 SQL, KV, R2, or Vectorize to extensions without leaking API keys.

### Scale-to-zero, pay-for-CPU

Idle code costs $0; hot paths spin up in milliseconds. Bills average ~70% less than duration-based models.

### Custom domains & white-label TLS

Your customers' brand, your performance—certs and routing handled automatically.

### Turnkey monetization

Track usage per tenant and plug into any billing system to charge for runtime, storage, or premium tiers.

## Use Cases

### SaaS platforms launching plugin ecosystems or integration marketplaces

Enable third-party developers to extend your platform safely

### Website & commerce builders embedding per-site business logic

Let customers customize their sites with custom code

### Agencies & dev shops shipping client-specific extensions without new servers

Deploy custom solutions for each client on shared infrastructure

### AI "vibe-coding" agents that run close to your data and users

Deploy AI agents that operate on your platform context and data

### Sandboxed execution included

Each customer runs in their own isolated Worker environment with automatic resource limits and security boundaries.

### Platform-first architecture

Built on Workers for Platforms to provide an out of the box multi-tenant layer, with global distribution included

### Multi-tenant ready

Your platform runs at the edge in 330+ cities worldwide — with [D1 databases](https://developers.cloudflare.com/d1/), [KV storage](https://developers.cloudflare.com/kv/), and [R2 object storage](https://developers.cloudflare.com/r2/) available per-tenant.

### Secure by design

Deploy both platform and customer code together — from [API routes](https://developers.cloudflare.com/api-shield/management-and-monitoring/api-routing/) to [serverless functions](https://developers.cloudflare.com/pages/functions/), all with automatic isolation.

### Monetization built-in

Built-in usage tracking, billing integration, and rate limiting help you charge for platform usage.
