Limits

Numeric ceilings come from limits in ocd capabilities --json on the node.

ocd capabilities --json
ocd --config /etc/open-compute/config.toml capabilities --json

Without --config, limits come from the embedded default config. Cloudflare plan numbers: Workers limits. Do not infer that this process enforces those request-scoped quotas.

Compatibility

Topic	Cloudflare	open-compute
Programming model is isolates, not unbounded host processes	Yes	Yes
Product-specific durable limits (KV key size, D1 statements, R2 objects, cache object size, …)	Plan / product quota	Frozen in platform config and emitted in limits
Request-scoped CPU / subrequest / simultaneous-connection quotas	Yes	Stock OSS workerd LimitEnforcer does not enforce them; those hosted quotas are not provided. This does not relax the public-address security boundary, product-specific limits, handle cleanup, or process supervision
Cache object default	Cloudflare product quota	16 MiB / 1 GiB logical body per Worker; see Workers Cache
