    > It brings the power of edge computing to your own infrastructure.I like the idea of self-hosting, but it seems fairly strongly opposed to the concept of edge computing. The edge is only made possible by big ass vendors like Cloudflare. Your own infrastructure is very unlikely to have 300+ points of presence on the global web. You can replicate this with a heterogeneous fleet of smaller and more "ethical" vendors, but also with a lot more effort and downside risk.

    The problem with sandboxing solutions is that they have to provide very solid guarantees that code can't escape the sandbox, which is really difficult to do.Any time I'm evaluating a sandbox that's what I want to see: evidence that it's been robustly tested against all manner of potential attacks, accompanied by detailed documentation to help me understand how it protects against them.This level of documentation is rare! I'm not sure I can point to an example that feels good to me.So the next thing I look for is evidence that the solution is being used in production by a company large enough to have a dedicated security team maintaining it, and with real money on the line for if the system breaks.

    Cool project, great work!Forgive the uninformed questions, but given that `workerd` (https://github.com/cloudflare/workerd) is "open-source" (in terms of the runtime itself, less so the deployment model), is the main distinction here that OpenWorkers provides a complete environment? Any notable differences between the respective runtimes themselves? Is the intention to ever provide a managed offering for scalability/enterprise features, or primarily focus on enabling self-hosting for DIYers?

    I did a huge chunk of work to split deno_core from deno a few years back and TBH I don't blame you from moving to raw rusty_v8. There was a _lot_ of legacy code in deno_core that was challenging to remove because touching a lot of the code would break random downstream tests in deno constantly.

    Isn't the whole point of Cloudflare's Workers to pay per function? If it is self-hosted, you must dedicate hardware in advance, even if it's rented in the cloud.

    I see anything that reduces the relience on vendor lock-in I upvote. Hopefully cloud services see mass exodus so they have to have reasonable pricing that actually reflects their costs instead of charging more than free for basic services like NAT.Cloud services are actually really nice and convenient if you were to ignore the eye watering cost versus DIY.

    Technically, and architecturally this is excellent. It’s also an excellent product idea. And I’m particularly a fan of the big-ass-vendor-inversion-model where instead of the big ass vendor ripping off an open source project and monetizing it, you look at one of their projects and you rip it off inversely and open source it — this is the way.

    Perhaps it might be helpful to some to also lay out the things that don't work today (or eg roadmap of what's being worked on that doesn't currently work?). Anyway, looks very cool!

    To the author: The ASCII-art Architecture diagram is very broken, at least on my Pixel phone with Firefox.These kinds of text-based diagrams are appealing for us techies, but in the end I learned that they are less practical. My suggestion is to use an image, and think of the text-based version as the "source code" which you keep, meanwile what gets published is the output of "compiling" it into something that is for sure always viewable without mistake (that one is where we tend to miss it with ascii-art).

    What if we hosted the cloud... on our own computers?I see we have entered that phase in the ebb and flow of cloud vs. self-hosting. I'm seeing lots of echoes of this everywhere, epitomised by talks like this:https://youtu.be/tWz4Eqh9USc
  • victorbjorklund
    Cool. I always liked CF workers but haven’t shipped anything serious with it due to not wanting vendor lock-in. This is perfect for knowing you always got a escape hatch.

    Good to see this! Cloudflare's cool, but those locked-in things (KV, D1, etc.) always made it hard to switch. Offering open-source alternatives is always good, but maintainign them is on the community. Even without super-secure multi-tenancy, being able to run the same code on your own stuff or a small VPS without changing the storage is a huge dev experience boost.

    Any reason to abandon Deno?edit: if the idea was to have compatibility with cloudflare workers, workers can run deno https://docs.deno.com/examples/cloudflare_workers_tutorial/

    Cool project, but I never found the cloudflare DX desirable compared to self hosted alternatives. A plain old node server in a docker container was much easier to manage, use and is scalable. Cloudflare's system was just a hoop that you needed to jump through to get to the other nice to haves in their cloud.

    This is super nice! Thank you for working on this!Recently really enjoying CloudFlare Workflows (used it in https://mafia-arena.com) and would be nice to build Workflows on top of this too.

    I wonder why V8 is considered as superior compared to WASM for sandboxing.
  • vmg12
    Does this actually use the cloudflare worker runtime or is this just a way to run code in v8 isolates?
  • dangoodmanUT
    This is similar to what rivet (1) does, perhaps focusing more on stateless than rivet does(1) https://www.rivet.dev/docs/actors/
  • st3fan
    This is very nice! Do you plan to hook this up to GitHub, so that a push of worker code (and maybe a yaml describing the environment & resources) will result in a redeploy?
  • theknarf
    Why would I want this over just sticking Node / Deno / Bun in a Docker container?
  • kachapopopow
    Could you add a kubernetes deployment quick-start? Just a simple deployment.yaml is enough.
  • utopiah
    DX?I'm quite ignorant on the topic (as I never saw the appeal of Cloudflare workers, not due to technical problems but solely because of centralization) but what does DX in "goal has always been the same: run JavaScript on your own servers, with the same DX as Cloudflare Workers but without vendor lock-in." mean? Looks like a runtime or environment but looking at https://github.com/drzo/workerd I also don't see it.Anyway if the "DX" is a kind of runtime, in which actual contexts is it better than the incumbents, e.g. Node, or the newer ones e.g. Deno or Zig or even more broadly WASI?

    Interesting option to consider next to openfaas
