      The actual app name would be good to have. Understandable they don’t want to throw them under the bus but it’s just delaying taking action by not revealing what app/service this was.

    Claude Code defaulting to a certain set of recommended providers[0] and frameworks is making the web more homogenous and that lack of diversity is increasing the blast radius of incidents

      The other day, I was forcing myself to use Claude Code for a new CRUD React app[1], and by default it excreted a pile of Node JS and NPM dependencies.

      So I told something like, "don't use anything node at all", and it immediately rewrote it as a Python backend, and it volunteered that it was minimizing dependencies in how it did that.

      [1] only vibe coding as an exercise for a throwaway artifact; I'm not endorsing vibe coding

        It emits Actix and Axum extremely well with solid support for fully AOT type checked Sqlx.

        Switch to vibe coding Rust backends and freeze your supply chain.

        Super strong types. Immaculate error handling. Clear and easy to read code. Rock solid performance. Minimal dependencies.

        Vibe code Rust for web work. You don't even need to know Rust. You'll osmose it over a few months using it. It's not hard at all. The "Rust is hard" memes are bullshit, and the "difficult to refactor" was (1) never true and (2) not even applicable with tools like Claude Code.

        • neilv 11 minutes ago
          How are you getting low dependencies for Web backend with Rust? (All my manually-written Rust programs that use crates at all end up pulling in a large pile of transitive dependencies.)
        • OptionOfT 10 minutes ago
          Except with using Rust like this you're using it like C#. You don't get to enjoy the type system to express your invariants.

      It's interesting how many of the low-effort vibecoded projects I see posted on reddit are on vercel. It's basically the default.
      • Aurornis 10 minutes ago
        Reddit vibecoded LLM posts are kind of fascinating for how homogenous they are. The number of vibe coded half-finished projects posted to common subreddits daily is crazy high.

        It’s interesting how they all use LLMs to write their Reddit posts, too. Some of them could have drawn in some people if they took 5 minutes to type an announcement post in their own words, but they all have the same LLM style announcement post, too. I wonder if they’re conversing with the LLM and it told them to post it to Reddit for traction?

    • elric 11 minutes ago
      Interstingly, a recent conversation [1] between Hank Green and security researcher Sherri Davidoff argued the opposite. More GenAI generated code targeted at specific audiences should result in a more resilient ecosystem because of greater diversity. That obviously can't work if they end up using the same 3 frameworks in every application.

      It's a good point, but I don't think the problem here is Claude. It's how you use it. We need to be guiding developers to not let Claude make decisions for them. It can help guide decisions, but ultimately one must perform the critical thinking to make sure it is the right choice. This is no different than working with any other teammate for that matter.

        No, the problem is the people building and selling these tools. They are marketed as a way of outsourcing thinking.

    • mvkel 7 minutes ago
      That's only looking at half of the equation.

      That lack of diversity also makes patches more universal, and the surface area more limited.

      The thing I can’t stop thinking about is that Ai is accelerating convergence to the mean (I may be misusing that)

      The internet does that but it feels different with this

      • themafia 53 minutes ago
        > convergence to the mean

        That's a funny way of saying "race to the bottom."

        > The internet does that but it feels different with this

        How does "the internet do that?" What force on the internet naturally brings about mediocrity? Or have we confused rapacious and monopolistic corporations with the internet at large?

        • mentalgear 10 minutes ago
          Indeed 'race to the bottom' seems more like capitalism in general.

      It's so trivial to seed. LLMs are basically the idiots that have fallen for all the SEO slop on Google. Did some travel planning earlier and it was telling me all about extra insurances I need and why my normal insurance doesn't cover X or Y (it does of course).
    • andersmurphy 1 hour ago
      That's the irony of Mythos. It doesn't need to exist. LLM vibe slop has already eroded the security of your average site.
      • egeozcan 48 minutes ago
        Self fulfilling prophecy: You don't need to secure anything because it doesn't make a difference, as Mythos is not just a delicious Greek beer, but also a super-intelligent system that will penetrate any of your cyber-defenses anyway.

          Explain more about this beer.
        • andersmurphy 37 minutes ago
          In some ways Mythos (like many AI things) can be used as the ultimate accountability sink.

          These libraries/frameworks are not insecure because of bad design and dependency bloat. No! It's because a mythical LLM is so powerful that it's impossible to defend against! There was nothing that could be done.

    What is the rationale for using vercel ? I'm getting a lot of value out of cloudflare with the $5/month plan lately but my bare metal box with triple digit ram has seen zero downtime since 2015.
    • deaux 2 hours ago
      They put a massive amount of VC cash into convincing people that Next.js was "the modern way" to create a website. Then they got lucky with the timing of LLMs becoming popular while they were the hot thing, leading LLMs to default to it when creating new websites. To picture that amount of VC cash - they're at Series F, and a huge chunk of that went towards marketing.

      Both have been changing as people realize it's rarely the right tool for the job, and as LLMs also become more intelligent and better at suggesting other, better options depending on what is asked for (especially Claude Opus).

      • apsurd 1 hour ago
        I really want this to be true. nextjs is a nightmare. I'm eternally disgruntled.

        nextjs is also powerful due to AI. But the value is a robust interactive front-end, easily iterated, with maybe SSR backing, nothing specific to nextjs (it's routing semantics + React).

        So much complexity has gone into SSR. I hate 5MB client runtime just to read text as much as anyone, but not if the tradeoff is isomorphic env with magic file first-line incantations.

        > To picture that amount of VC cash - they're at Series F, and a huge chunk of that went towards marketing.

        I guess they should have put some of that marketing money into hiring someone to manage the security of their systems. It's pretty telling that they had to hire an "incident response provider" just to figure out what happened and clean up after the hack. If you treat security like something you don't have to worry about until after you've been hacked you're probably going to get hacked.

      • mrits 50 minutes ago
        So glad I decided to just stick with django/htmx on my project a few years ago. I invested a little time into nextjs and came to the conclusion that this can't be the way.

      You use a free template that's done in Next.js and uses its Image component, so you need a server.

      Everything runs fine locally until you try to deploy it, and bam you need 4g ram machine to run the thing.

      So you host it on Vercel for free cause it's easy!

      Then you want to check for more than 30 seconds of analytics, and it's pay time.

      • systemvoltage 1 hour ago
        I am not following the logic. If you’re a hobbyist, sure.

        But the argument is if you’re using Vercel for production, you’re paying 5-10x what you’d pay for a VM, with 4gb.

        So then what’s the rationale? You can’t be a hobbyist but also “it’s pay time” for production?

        • rwyinuse 1 hour ago
          Perhaps the rationale is laziness. Maintaining VM probably takes some more effort and competence than deploying to Vercel. Some people are willing to pay to minimize effort and the need to learn anything.
          • ajdegol 33 minutes ago
            Vercel auto creates deployments on pushes to branches. That was a super useful feature in beta testing web stuff.

      Very nice developer experience. A lot of batteries included, like CDN, incremental page regeneration, image pipeline or observability. Not having to maintain a server.

      I’m still planning to move elsewhere though, the vendor lock-in is not worth it and I’d like to keep our infra in the EU.

        • fontain 33 minutes ago
          Cloudflare’s developer experience doesn’t come close, it is terrible. Cloudflare are working on it, and hopefully they’ll be a real competitor to Vercel on ease of use someday, but right now, it is painful when compared to Vercel. Cloudflare is infrastructure first, Vercel is developer experience first.
    • gherkinnn 43 minutes ago
      I haven't used Cloudflare and am the first to shit on Vercel. But I have to say, some aspects of their hosting are nice. In many ways it really is just a terminal command and up it goes with good tooling around it. For example, the PR previews take zero setup and just work. Managing your projects is easy, it's all nicely designed, it integrates well with Next and some other frontend-heavy systems and so on.
    • kandros 1 hour ago
      For many people Vercel is Easy (not simple)

      Knowing how to operate a basic server is perceived as hard and dangerous by many, especially the generation that didn’t have a chance to play with Linux for fun when growing up

    • hdkfov 40 minutes ago
      Out of curiosity what are you using cloudflare for that it costs $5 and who do you use for the baremetal box?
    • dev360 2 hours ago
      For a lot of folks, I think its ease of deployment when using Next.js. I switched to astro, also doing a lot of cloudflare at the moment. Before that, I was doing OpenNext with sst.dev on AWS but it started feeling annoying.
    • victorbjorklund 1 hour ago
      If you are using nextjs it is easier because vercel done a lot of things to make it a pain to host outside of vercel.
      • Bridged7756 33 minutes ago
        Do you have any examples?. I'm not that acquainted with the pains of deploying Next apps, though I've heard that argument being used.
    • kingleopold 2 hours ago
      it's free for newbies and everyone, ofc it's a trap but freemium model gets people. aws can cost easily few thousands with 2-3 mistakes and clicks. vercel makes you start free then if you grow they bill you 10x-100x aws
      • arealaccount 50 minutes ago
        I dunno I put a lot of traffic through Vercel, maybe 100k visitors per day, and it was under a few hundred a month. I think a couple EC2 instances behind a load balancer would cost similar or more. I was under the impression that its still a VC subsidized service.

        They regularly try to get me to join an enterprise plan but no service cutoff threats yet.

    • Bridged7756 2 hours ago
      I suppose their market is one click deployments. Maybe for non technical people or people not willing to deal with infra.

    • locallost 2 hours ago
      I started using it a few years ago when I moved to my current company, and have to say I've learned to like it quite a bit. Moving to Cloudflare is an option, but currently it just works so we can't be bothered. Costs are not nothing, but basically no issues with it until now, and it's not so expensive that it raises eyebrows with the biggest being that we have 3 seats. The setup is quick and again it just works. We are a very small team, and the fact we don't have to deal with it on a daily/weekly basis is valuable. Obviously this current situation is a problem, but I am not sure which platform is free of issues like these. People act like it can't happen to me, until it does.

      0.82% of homes are burglarized every year.

      Meaning since 2015, you’ve got an 8.2% chance of having someone walk out with that box. Hopefully there’s nothing precious on it.

      • jimberlage 2 hours ago
        Assuming that all homes are at equal risk of being burglarized. In practice the neighborhoods I’ve seen are either at much higher risk or much lower risk.
        • 0123456789ABCDE 2 hours ago
          and burglarized homes have higher prob. of being burglarized again, and probabilities don't accumulate but compound, and is the server even in a house?

          The chance of being burglarized is not the same as the chance that when you are hit, they decide to take your webserver. Think it through.
