Products that do what Marvin, your own AI-powered game studio does
We’ve spent years working at large game studios, and one thing we saw repeatedly is how hard it is for a small team—or an individual—to not just build a game, but to run one like a sustainable business. We wanted to make those capabilities accessible to anyone and for anybody to bring their ideas to life. Marvin works through a set of specialized agents you can talk to directly. You can describe the game you want to build, and the agents collaborate with you on design, mechanics, art, physics, progression systems, and level creation. From there, you can publish the game to different…

I'm using AI (mostly Claude) to create/publish a new video game every day This is day 33, first stab at the tower defense genre. Most of the games (including this one) I build with a single prompt. Rarely, a couple extra prompts are needed for bug fixes or to tweak the physics/UI. Extremely rarely, the AI has difficulty making the game work right (usually drawing it) and it takes a dozen or more prompts -- but the majority of the time, it gets everything right and makes a fully playable game first try Happy to answer any questions, just a little hobby project of mine I'm having…

Founder here. I built NEO, an AI agent designed specifically for AI and ML engineering workflows, after repeatedly hitting the same wall with existing tools: they work for short, linear tasks, but fall apart once workflows become long-running, stateful, and feedback-driven. In real ML work, you don’t just generate code and move on. You explore data, train models, evaluate results, adjust assumptions, rerun experiments, compare metrics, generate artifacts, and iterate; often over hours or days. Most modern coding agents already go beyond single prompts. They can plan steps, write files, run…

Hey HN, I wanted to see what happens if you put a large group in control of a site that’s completely built and updated by an AI agent. See the site here: https://youarethepm.com. I first tried this with a small group of co-workers and it worked surprisingly well, so the obvious next step was: give it to a bigger group of strangers and see what we learn. This site is fully autonomous. An AI agent reads this thread, decides what to do, writes code, and ships updates on a virtual computer. I might step in if it gets totally stuck, but the goal is for the site to evolve primarily based…

Hi HN, I am Erik Bethke, game dev that has been making online games for 30+ years (Starfleet Command, GoPets, FarmVille, Mafia Wars). For the last 3 years I have been building Bike4Mind and now I have to put my big boy pants on and 'go to market'. Ugh, it would be so much more cozy to fire up a few more agents and fix a few more bugs, polish some more UX - or hey how about a new feature that does Q, R or S? What is Bike4Mind? I started Bike4Mind to be the home of a bunch of AI augmented game development tools, and over time have just kept adding features. It is a full cognitive workbench we…

Hi everyone, We have been developing a platform to enable professionals to build AI assistants to help them through their work. After a few months, we realized people are trying to sell basic functionalities that can be built from scratch in a couple of hours. Due to this, individuals who are not familiar with the current SOTA are misinformed about the potential of generative models. So, we decided to open up some of our most popular templates as standalone tools for free to empower individuals and set a solid standard for what people should expect. We believe the barrier to accessing…

Most AI applications are built for individuals but work happens in groups and humans want to collaborate with both agentic AI and other teammates in the same session. We created Hybrid Groups for that purpose. In Hybrid Groups, agents join group chats as virtual team members in Slack and GitHub. They participate in group conversations, proactively contribute when needed and perform actions on behalf of individual users, like managing your calendar for meeting suggestions or updating your todo list without sharing access to your private resources to the group. The project is open-source at…

Hey HN, We started out building a whole game-making platform: engine, editor, templates, the lot. It was a slog, and it kept fighting the thing that made it interesting: the models got good. With Opus 5, Fable 5, SOL 5.6, a one-prompt Three.js or Canvas game already looks genuinely great, and the models know those APIs far better than they'd ever know our harness. Forcing people through our engine meant limiting them to it, while solving the part AI solved better than us trying to buold the harness The part it can't solve is multiplayer. A generated game is usually a single HTML file; making…

Hey HN, Most AI “agents” I’ve tried are basically chatbots with amnesia — they forget everything the moment you close the tab and can’t do anything unless you’re sitting there watching them. I wanted real AI coworkers that just… work. So I built Computer Agents (aiOS). Every agent you create gets its own isolated computer in the cloud — complete with persistent memory, a real file system, code execution environment (with automatic dependency management), and the ability to run scheduled or webhook-triggered tasks 24/7. You give it a goal (“research this market and email me a report…

Hi HN, I'm one of the engine programmers at All Out Games (https://allout.game/), a multiplayer-first gaming UGC platform where creators can make and play games with their friends. For scripting we wanted our creators to be able to jump in and create game mechanics without having to think about networking. If a developer had to manually send packets to/from client/server to get things to happen then we have failed. It is particularly bad if you are using AI tools because they struggle to keep in mind what code is meant to run where (client, server, or both) and…

Hello, HN! I've posted a couple times here to get feedback on a strategy game I've been working on called Meatshields. All of your suggestions and feedback have been EXTREMELY helpful so I want to thank everyone here once again for generously helping me iron out kinks in the game. One big request I got the last time I showed the game was the ability to write your own AI for it. I thought about it and realized that would be totally do-able! The downside is that you have to host the AI service yourself, so it's sort of BYOAI, but it won't need to support a massive ton of requests or anything…

Hi HN! I'd love your feedback for this AI storytelling game. Remember when you used to read choose-your-own adventure books as a kid? We're trying to re-create that. The site lets you create adventures by seeding them with parameters that end up feeding LLMs: title, genre, writing style, etc. Once you've done that, you can play your book like a game: with custom chapters, illustrations, voice narration, choices, and dice rolls. We’re really into the idea of merging the open-ended generative AI with goal-directed story arcs that the game author can control. Everything is open source (links…

I built a multiplayer strategy game for AI agents called Artifice. You give an agent a strategy prompt and it plays on its own. Games are 4 players, 25 turns, simultaneous actions, fog of war, and free-text diplomacy between agents. The main entry point is the site: https://artificegame.com And here is the github repo: https://github.com/burakcan/artifice You can watch live games there with the full map, troop movements, and private messages between agents. A lot of the fun has come from the playtests. In one of them, an agent was told to play like an old man…

Coding agent management is all the rage right now, and many tools are being created to fill the gap. As a power user for all tools I've used since I've started my software engineering career, I've always taken the time to test multiple tools thoroughly before deciding on one, and an agentic manager was no different. I've tested many tools, but ultimately landed on Agent of Empires (AoE for short). Why ? Because it's fast, the development is active and it's feature complete, and easy to contribute to. So I did (contribute). In my day to day workflow for my job, I need the ability to start…

I have a favour to ask. I’ve been working for a while on Kalavai, a project to make distributed AI easy. There are brilliant tools out there to help AI hobbyists and devs on the software layer (shout out to vLLM and llamacpp amongst many others!) but it’s a jungle out there when it comes to procuring and managing the necessary hardware resources and orchestrating them. This has always led me to compromise on the size of the models I end up using (quantized versions, smaller models) to save cost or to play within the limits of my rig. Today I am happy to share the first public version of our…

Hi HN, I built AgenTank. It is a small game where an AI agent writes the logic for your tank. You watch it fight, give strategic feedback, let the agent update the tank code, and send it back into battle. I have run 1,000+ battles on my own tank and spent about $200 in Claude credits improving it. The part I enjoy most is not just winning, but watching the tank make visible mistakes, thinking of a better strategy, and seeing whether Claude can turn that into better code.

Sup HN! Dipanshu and Rushant here from Caspian. One is a functional programmer and the other has been deploying AI employees. Together we realized how agents have communication bottleneck. Given the coming agentic economy, we had a thought experiment on what can be the key infrastructure for agents as they get better. Our inspiration for solving for communications infra came from our own time spent just setting up comms while we were deploying open claw for companies plus we noticed about 15%+ of issues in Openclaw and Hermes were that of comms. So we abstracted the headache of reliable…

Hi HN, I’ve been working on an AI-powered website builder that allows anyone to create a fully functional website in just a few minutes. No coding, no design skills—just a simple, intuitive process with AI handling the heavy lifting. Here’s what you can do with it: • Create a website by entering a name, description, and subdomain. • Use AI to design the site, customize content, and edit sections with simple prompts. • Preview, tweak, and publish your website live instantly. • Download the code for full flexibility if you want to self-host or integrate. It’s still an MVP, and I’ve got lots of…

Hi hn, Its been a while since my kid has been dreaming to make videogames, as you know, the entry bar is high, too many technical details are involved. A few months ago, we started making games, we have tried many different ways, from dragging blocks to write code with a high-level library to make it simple, it is still too much work. Getting into the AI boat, I decided to give it a try for making games, turns out that it works super nicely, still, you still have many technical concepts involved, what language should the game be written in? where do you store the file/assets? how do you…
