Cloudflare for Platforms

Build your own multitenant platform using Cloudflare as infrastructure

Cloudflare for Platforms lets you run untrusted code written by your customers, or by AI, in a secure, hosted sandbox, and give each customer their own subdomain or custom domain.

Who is Cloudflare for Platforms for?

Cloudflare for Platforms is designed for teams building products where end users need to run code, store data, or get their own domain. Common use cases include:

AI coding platforms — Let users describe apps in natural language, generate code with AI, and deploy instantly
E-commerce and website builders — Power storefronts where merchants customize behavior, add integrations, or write their own logic
Low-code / no-code platforms — Let non-developers build and deploy applications without managing infrastructure
Developer tools and SaaS products — Allow customers to extend your product with custom scripts, webhooks, or plugins

Platform Capabilities

You can think of Cloudflare for Platforms as the exact same products and functionality that Cloudflare offers its own customers, structured so that you can offer it to your own customers, embedded within your own product. This includes:

Custom Domains and Subdomains — you call an API to create custom subdomains or configure custom domains for each of your customers
Isolation and multitenancy — each of your customers runs code in their own Worker — a secure and isolated sandbox
Programmable routing, ingress, egress and limits — you write code that dispatches requests to your customers' code, and can control ingress, egress and set per-customer limits
Databases and storage — you can provide databases, object storage and more to your customers as APIs they can call directly, without API tokens, keys, or external dependencies
Infinite scale — Deploy millions of applications, domains, and resources (e.g. databases) without managing infrastructure. Cloudflare automatically scales with your platform.
