Workers for Platforms

If customers can run plugins, functions, integrations, or other custom code in your product, Workers for Platforms is one of the few managed services built for the problem. Dispatch namespaces hold unlimited user Workers, while custom limits and outbound Workers control what tenant code can do and see. Cloudflare handles isolation and per-tenant resource limits, saving you from building a safe multi-tenant container platform yourself.

The gaps pull the score down. Tenant Workers do not get Durable Objects, cutting off many stateful uses available on the main platform. There is no preview or staging system, so tenants deploy with less confidence than first-party Workers users. Observability barely reaches dispatch namespaces either. Proper logs, traces, and per-tenant error aggregation are all pipelines you have to build yourself.

Nothing else in the market really competes with the isolation model, which is why this isn’t lower. But the difference between “unique primitive” and “complete platform” is exactly the difference between what it is and what it charges like.
