    For an alternative to airplane.dev, you can checkout Windmill.

    https://github.com/windmill-labs/windmill

    "Open-source developer infrastructure for internal tools (APIs, background jobs, workflows and UIs). Self-hostable alternative to Airplane, Pipedream, Superblocks and a simplified Temporal with autogenerated UIsm and custom UIs to trigger workflows and scripts as internal apps.

    Scripts are turned into sharable UIs automatically, and can be composed together into flows or used into richer apps built with low-code. Supported script languages supported are: Python, TypeScript, Go, Bash, SQL, and GraphQL. "

    I'm genuinely curious what server-side stuff on BC you are referring to. That may have been something added after our assessment. The way I'd generally approach something like that for any of the platforms would be using an external low/no code solution to process webhook data. But it would depend heavily on the use case. For a more developer friendly option I've been really impressed by windmill.dev. We use a mix of n8n and windmill for various needs.

  • Show HN: Windmill – fastest open-source workflow engine – the how
    6 projects | news.ycombinator.com | 22 Nov 2023
    Yes it goes in that direction, however note that you can already do this in a not too hard way.

    Our openflow spec is both open-source and has a full openapi definition: https://github.com/windmill-labs/windmill/blob/main/openflow...

    you can use that to generate client sdks in any languages and build your own dag with it. That's what one of our customer did building a reactflow to openflow library: https://github.com/Devessier/reactflow-to-windmill

    It's not as good as the decorator way but we move fast and if you still have interest for it we could prioritize it (and ask for feedbacks :))

  • GitHub Actions Are a Problem
    19 projects | news.ycombinator.com | 12 Nov 2023
    We have built an open-source generic workflow engine to run arbitrary scripts (https://windmill.dev) with a vscode extension to build the yaml using a low-code builder and each individual script in their dedicated python/ts files so you get your full editor assistants https://youtu.be/aSOF6AzyDr8?t=116

    One of the area we are expanding next is a github app so you get exactly the same UX as github actions but running windmill workflows on your windmill workers.

  • Cloudflare acquires PartyKit to allow developers to build real-time multi-user
    3 projects | news.ycombinator.com | 5 Apr 2024
    Standards bodies only standardize things after they've been proven to work. You can't standardize a new idea before offering it to the market. It's hard enough to get just one vendor to experiment with an idea (it literally took me years to convince everyone inside Cloudflare that we should build Durable Objects). Getting N competing vendors to agree on it -- before anything has been proven in the market -- is simply not possible.

    But the Durable Objects API is not complicated and there's nothing stopping competing platforms from building a compatible product if they want. Much of the implementation is open source, even. In fact, if you build an app on DO but decide you don't want to host it on Cloudflare, you can self-host it on workerd:

    I think this is for people who want to run their own cloudflare workers (sort of) and since nobody wants to run full node for that, they want a small runtime that just executes js/wasm in an isolated way. But I wonder why they don't tell me how I can be sure that this is safe or how it's safe. Surely I can't just trust them and it explicitly mentions that it still has file IO so clearly there is still work I need to do customize the isolation further. But then they don't show any info on that core usecase. But then that's probably because they don't really want you to use this to run it on your own, they are selling you on running things on their edge platform called "Wasmer Edge". So that's probably why this is so light on information.. the motivation isn't to get you to use this yourself, just to use this their hosted edge platform. But then I wonder why I wouldn't just use https://github.com/cloudflare/workerd which is also open source. Surely that is fast enough? If not then it should show some benchmarks?

    i love how the main reference for workerd can be just one capnp file.

    https://github.com/cloudflare/workerd/blob/main/src/workerd/...

    this changed my world how i think about computing on the web.

    if there was just a good enough js library as for lua and you could directly send capnp messages to workerd instead of always going through files. I guess one day i have to relearn c++ and understand how the internals actually work.

  • Am I out of touch for trying to limit my stack to containers?
    1 project | /r/ExperiencedDevs | 18 May 2023
    Edge runtimes are very good alternatives to containers that shouldn't be dismissed for "not being containers". They're often faster, more scalable, and cheaper than containers. Them being so lightweight also enable a "nanoservice architecture" – being able to run every service on a single computer instead of running different services on different computers and having to deal with network latency and unreliability.
