True, workerd is open source. But the bindings (KV, R2, D1, Queues, etc.) aren't – they're Cloudflare's proprietary services. OpenWorkers includes open source bindings you can self-host.

I tried to run it locally some time ago, but it's buggy as hell when self-hosted. It's not even worth trying out given that CF itself doesn't suggest it.

		I'm curious what bugs you encountered. workerd does power the local runtime when you test CF workers in dev via wrangler, so we don't really expect/want it to be buggy..
