All these tools to build something, but nothing to build. I feel like I am part of a Pyramid Scheme where every product is about building something else, but nothing reaches the end user.
Note: nothing against fluid.sh, I am struggling to figure out something to build.
For problems that can be solved with only a small amount of simple code that is true. However software can become very complex and the larger/more complex the problem is the more important software developers are. It quickly becomes easier to teach software developers enough of your domain than to teach domain experts software.
In a complex project the hard parts about software are harder than the hard parts about the domain.
I've seen the type of code electrical engineers write (at least as hard a domain as software). They can write code, but it isn't good.
It is my experience that most of these business domain experts snore the moment you talk about anything related to the difficulties of creating software.
I’ve been a year deep into my first job out of tech. There is a never ending slew of problems where being able to code, specially now with AI, means you have wizard-like powers to help your coworkers.
My codebase is full of one-offs that slowly but surely converge towards cohesive/well-defined/reusable capabilities based on ‘real’ needs.
I’m now starting to pitch consulting to a niche to see what sticks. If the dynamic from the office holds (as I help them, capabilities compound) then I’ll eventually find something to call ‘a product’.
I find myself building fun tools for myself and things that help with quality of life slightly, but I don’t need all this extra enterprise stuff for that. I actually find myself more likely to use something I built because I am proud of it, even if there is already something on the market that addresses my need.
I’m really enjoying these LLMs for making ad-hoc tooling / apps for myself. Things that I inly need for a day or a week, that don’t need to work perfectly (i can work around bugs).
It’s really liberating. Instead of saying “gosh I wish there was an app that…” i just make the app and use it and move on.
Side note, been watching gold prospecting channels lately, there will be these dig sites/claims people go to, they'll do their thing, dig a hole, run it through some angled ramp water contraption... they get like nothing, it's the experience I suppose. But I was wondering what the owner gets from all these people showing up.
Someone on HN pointed out how all the LLM companies are basically going “we made this thing, can y'all please find the billion dollar application of it?” and that really made a lot of things - namely why I’m frequently raising an eyebrow at these tools and the vague promises/demand that we use them - click into place.
Don’t get me wrong, I have found uses for various AI tools. But nothing consistent and daily yet, aside from AI audio repair tools and that’s not really the same thing.
There are companies making a lot of money directly from software largely written by LLMs especially since Claude Code was released, but they aren't mentioning LLMs or AI in any marketing, client communications, or public releases. I'm at least very aware that we need to be able to retire before LLMs swamp or obsolete our niche, and don't want to invite competition.
Outside of tech companies, I think this is extremely common.
Lol, that does sounds a little scary but if it works it works. Mainly I built this to prevent there being a chance that changes affect production. This is meant to be used with scale (say hundreds of VMs) vs 1. From a safety perspective running Claude Code with just a watchful eye would not fly in my environment, which is why I built something like this.
I've noticed a lot of LLM-based tools that are essentially this sort of thing. Just a slightly more specific prompt wrapper around the core capability that can already do the thing. It's so bad.
Yeah. The times I have let claude off the read-only leash, it's gone fine for me too (with stern warnings not to do anything stupid, and a close eye). But that's not really solving the same problem as this project, I guess. From what I can see this is using a safer and more reproducible method (and not k8s native, so it feels a little foreign to me).
I do the same. I was thinking about creating read-only kubeconfigs for him to make sure it can't do bad stuff but with a good SKILL.md, it works perfectly.
Hey HN,
My name is Collin and I'm working on fluid.sh (https://fluid.sh) the Claude Code for Infrastructure.
What does that mean?
Fluid is a terminal agent that do work on production infrastructure like VMs/K8s cluster/etc. by making sandbox clones of the infrastructure for AI agents to work on, allowing the agents to run commands, test connections, edit files, and then generate Infra-as-code like an Ansible Playbook to be applied on production.
Why not just use an LLM to generate IaC?
LLMs are great at generating Terraform, OpenTofu, Ansible, etc. but bad at guessing how production systems work. By giving access to a clone of the infrastructure, agents can explore, run commands, test things before writing the IaC, giving them better context and a place to test ideas and changes before deploying.
I got the idea after seeing how much Claude Code has helped me work on code, I thought "I wish there was something like that for infrastructure", and here we are.
Why not just provide tools, skills, MCP server to Claude Code?
Mainly safety. I didn't want CC to SSH into a prod machine from where it is running locally (real problem!). I wanted to lock down the tools it can run to be only on sandboxes while also giving it autonomy to create sandboxes and not have access to anything else.
Fluid gives access to a live output of commands run (it's pretty cool) and does this by ephemeral SSH Certificates. Fluid gives tools for creating IaC and requires human approval for creating sandboxes on hosts with low memory/CPU and for accessing the internet or installing packages.
I greatly appreciate any feedback or thoughts you have, and I hope you get the chance to try out Fluid!
Why would you not put a description like this on your actual website? Your homepage does not explain anything about what this actually does. Are you really expecting infrastructure engineers to install your app with a bash command after only providing the following information?
Claude Code for infrastructure. Debug, act, and audit everything Fluid does on your infrastructure.
Create sandboxes from VMs, investigate, plan, execute, generate Ansible playbooks, and audit everything.
This allows the agent to make any changes in a production clone vs agents running on a production VM. For example, you wouldn't want claude editing crucial config on the chance it brings everything down vs letting it do in a cloned environment where it can test whatever.
Clever solution. I think ops (like this) and observability will be pretty hot markets for a while soon. The code is quite cheap now, but actually running it and keeping it running still requires some amount of background. I've had a number of acquaintances ask me how they can get their vibe coded app available for others to use.
I really like this idea. I do a lot of kubernetes ops with workloads I'm unfamiliar with (and not directly responsible for) and often give claude read access in order to help me debug things, including with things like a grafana skill in order to access the same monitoring tools humans have. It's saved me dozens of hours in the last months - and my job is significantly less frustrating now.
Your method of creating ansible playbooks makes _tons_ of sense for this kind of work. I typically create documentation (with claude) for things after I've worked through them (with claude) but playbooks is a very, very clever move.
I would say something similar but as an auditable, controllable kubernetes operator would be pretty welcome.
The real problem is just the volatility for the employees. Unless Board of Directors/Owners punish downtime, you risk a dark pattern of uptime just being a nice-to-have when I can just replace any expertise with the next kid out of college + Claude.
So you really need customers to react. And this isn't theoretical - people have already lost their jobs and there's really, really good people in the market available right now.
- The website tells less than your comment here. I want to try but have no idea how destructive it can be.
- You need to add / mention how to do things in the RO mode only.
- Always explain destructive actions.
Few weeks ago I had to debug K8S on the GCP GDC metal, Claude Code helped me tons, but... I had to recreate whole cluster next day because agent ran too fast deleted things it should not delete or at least tell me the full impact. So some harness would be nice.
Many places have "dev", "test" "prod"... but IMHO you need "sandpit" as well.
From an ops point of view as orgs get big enough, dev wraps around to being prod-like... in the sense that it has the property that there's going to be a lot of annoyed people whose time you're wasting if you break things.
You can take the approach of having more guard rails and controls to stop people breaking things but personally I prefer the "sandpit" approach, where you have accounts / environments where anything goes. Like, if anyone is allowed to complain it's broken, it's not sandpit anymore. That makes them an ok place to let agents loose for "whole system" work.
I see tools like this as a sort of alternative / workaround.
Sandpit should be a personal (often local, if possible) dev environment. The reason people get mad about dev being broken for long periods of time is that they cannot use dev to test their changes if your code (that they depend on) is broken in dev for long periods of time.
Note: nothing against fluid.sh, I am struggling to figure out something to build.

There are an infinite amount of problems to solve.
Deciding whether they’re worth solving is the hard part.

Scary? A little but it's doing great. Not entirely sure why a specialized tool is needed when the general purpose CLI is working.

Interesting idea, few things:
- The website tells less than your comment here. I want to try but have no idea how destructive it can be.
- You need to add / mention how to do things in the RO mode only.
- Always explain destructive actions.

But particularly for devops / systems focused work, you lose too much "test fidelity" if you're not integrating against real services / cloud.
