Sites in ChatGPT

I have been using Sites a few months now, really underrated feature IMO. Any time I get a quick app idea I just hand it off to Sites and usually get a working prototype within the hour.

For example, here's a game where you are a mouse hunting for cheese in higher dimensional mazes: https://manifold-six-axis-escape.nathan338932.chatgpt.site/

Idea came to me while at a concert, was ready to play that same night.

People seem calm in here, but I really now think is replacing a lot of industries. Like Website Designer. I totally see people asking chatgpt to build them a website instead of paying them 2,000 USD.

Soon it will connect to Ads and it will runs for it as well.

Honestly since Opus 5.5, Opus is my interface for 95% off my work. I don’t open emails anymore i let it summarize draft and handle most of the work and I only talk to Claude and not read/write the emails myself.

I also barely go in analytics dashboards anymore, Most I do is creating artifacts to explain if text is not enough for me to understand.

I’m going to bed. I have analytics running for every cancellation on my software to see what goes on. I have a/b tests running that are getting interpreted automatically. My bugs are getting fixed automatically.

I can monitor my competitors and copy every feature a/b test resolution they’ve done instantly for (3$ of my budget)

I’m an early adaptor of the latest models. The labs will have better tools already, but it really feels like a breaking point. What’s normal for me today is normal for more tomorrow and the friction has never been lower...

Interesting..

Look at the "beneath the surface" example. Click on a creature close-up. Click the "rotate creature" button. The creature's rectangular jpeg, complete with black background, rotates on screen. No 3d or anything. This is their demo! It has that Potemkin village quality, much like AI apps, code, and answers.

I wonder if they'll combine this with the currently-in-closed-beta Sign In with ChatGPT to let people make sites that can make inference calls that get charged to the user's ChatGPT subscription rather than the site owner's API billing account, like Claude Artifacts already lets you do. That would synergize well with ChatGPT Sites being generally more robust and feature-complete than Claude Artifacts.

The idea is great but the websites shown as examples are clearly made by AI because they make no sense.

Current AI is NOT going to replace web devs or coders because it cannot tabula rasa make human sense. I suspect the reverse with a Jevons thingy happening

This is probably going to be hugely successful with the majority of the population.

I took it for a spin. I used Claude to create a self contained HTML file with JSON data embedded to create a SVG bar chart with sort and filter buttons. I then gave the HTML file to ChatGPT Work and it created the site using the provided HTML code unadulterated.

I then asked the next question. How can I automatically update the embedded JSON data. It gave two answers which I thought was weird. First, it said I could using a plugin to an MCP server. Second, it said I could use an API and when I asked for which API... it said there was an API available in ChatGPT Sites but no details. So I assume it can be done.

What I am thinking of is to use ChatGPT sites as a replacement for SharePoint. I can create self contained HTML charts and let employees view it within our enterprise instance of ChatGPT. The piece I am working on is how to automatically update the embedded data from our database.

This seems to close a gap that both Claude and chatgpt had.

If you ask something like "please make a little website for me and my friends to plan our shopping lists on", I would expect the result to be:

"Here you go: https://shopping-lister.chatgpt.com/"

Unfortunately right now most AI models get into the weeds of asking the user to sign up to netlify or firebase or buying a domain etc - none of which most users are interested in doing.

Very polished. I suspect OpenAI will abandon this project at some point to focus on other core products. This kind of feature is great, but it spreads them thin, and other players like Cloudflare are rolling hard to provide this kind of convenience to agents with far greater depth. This is not a judgement against ChatGPT Sites - it's a well-executed product.

Looks very useful.

I’ve been using exe.dev to throw up micro sites. It has a built in web agent and first party mobile app agent. And any coding agent that can use “ssh” (all of them) can easily figure out how to drive it.

It also has a lot more developer and PaaS tools like GitHub integration.

RIP Heroku for imploding before the wave of vibe coding. We had the ability to “spin up a free app on the internet” before it was cool.

I was imagining the other day what other "apps" that frontier labs can get into. If we had "Claude Mail" or "ChatGPT for Workspaces" it would be very interesting. Email service created by Claude, then docs (they have it already?) then all the business apps layer (heck integrate your vibe coded apps onto these! build your own slack, CRM)

If models are commoditized and apps is where the grab is - I actually wouldn't mind a new email provider - GMail has not practically changed in the last 10 years I feel.

Something I've been thinking a lot about recently is how much we still need UIs vs if we'll just interact with agents.

We have a platform that enables building both and I still find UIs to be quite relevant. Especially if it's so easy to build like in this case because you can always throw together a visualization for something quickly and then never look at it again.

This looks really cool and because I'm in a tangential space I know how fun and useful it's been to build and host stuff on the web quickly.

We're geared towards fully-fledged (serverless) apps and agents for internal use only though, in case it's of interest to anyone: https://railcode.dev/

Looks like a jab at Lovable.

Wonder what domain they're going to pick next. I feel like many LLM-dependent businesses are going to get sherlocked by OpenAI and Anthropic.

Sites is so good that it’s changed my workflow - I start in Opus 5.5, have it write a plan to Google Docs in markdown, then have Codex pick up the plan, shave it down, and build the prototype. A little annoying to switch tools, annoying enough to only do this on desktop, but the output is fantastic.

They are desperate to find a moat cause models aren’t much more than a commodity.

What they might not realise is that stuff/services like these (ChatGPT Sites) are probably not much of a moat either in a world where majority of population has access to increasingly better models capable of building competitors in days if not hours. Even if they restrict usage of their models when it comes to creating competitor services there will always be other models that you can use to build competitor.

What is happening is that their products are putting people out of work but at the same time they are also enabling anyone to easily build competitors to their own products and are thus putting their own services “out of work”. They are essentially eating their own tail. Ouroboros. Is noone seeing that?

The only truly lasting moat might be hardware/compute. At least for now.

Are there any significant differences between Claude Artifacts and this?

Gonna wager good money they attempt to relaunch Apps or something of the sort, where you build, launch, host within ChatGpt, seamlessly making it easier really soon.

Then the app economy gets going within ChatGPT

I’m getting dejavu. Is this the 2026 version of Yahoo GeoCities

My fun little project has been Sherlocked! https://weejur.com

For whatever reason most of the sites are Arabic-language prototypes for things like plumbing companies. I'm not sure why - if those are solving a real problem, or whether someone is running a scam, or what.

I think this is the next step in the evolution of AI based tools. We can develop the app or tool, but we need somewhere to easily publish it.

I actually recently shared my own version of this concept, but self hosted. I'm optimistic that there can't be much lock-in from the big providers, but I think there's a large market to capture

Funny how the showcased "Tidal house" has unreadable text on an image.

https://tidal-house-retreat.openai.chatgpt.site/

> Quiet cabins. A view of your own.

They'd better be proactive with checking for abusive users, because I can easily see people trying to spin up honeypots, crypto miners, scam sites, etc. on this. Especially given that the hosting appears to be free with undefined CPU/RAM limits.

Looks good. Like most ChatGPT things, though, it will probably take good prompting and iteration, to ensure that the sites have individuality.

Still, I suspect a lot of independent Web developers are sweating. It was already getting tough, but this is a coffin nail.

i love sites

i make it for anything, i made one as a food guide for the UW chow down https://uw-chow-down-2026.corruptbytes.chatgpt.site/

Probably the most underwhelming feature of Chatgpt. I dont know why its so slow and overall terrible as compared to Claude artifacts

I've been using this for probably six weeks. It just popped up as an option one day in Codex.

We’ve been building something like this, but perhaps even more powerful, safe, and beginner friendly. If Sites looks like it’s the right speed for you, we’d love your feedback on https://vibes.diy/

Is there anything similar that's open source and self hosted and can be hooked into any agent via MCP?

I know that Vercel or something similar is quite close to that, but it's not that well integrated into MCP/Skills.

I'd like to have one of this but where the content is dynamically updated by a 'cloud' agent on schedule, is this feasible today?

My guess is Google and Apple are going to eventually take all the market share for this "app builder" category. They own the device market-share and can offer way better integration

Seems like Ploy, I think.

Does anyone know if Claude makes it easy to publish sites u vibe coded to a custom subdomain or new domain? That’s the biggest reason I use this feature in ChatGPT over Claude

impressive, but brand websites mostly "eaten" by curated accounts in social media

Sadly while the example: https://below-the-surface-ocean.openai.chatgpt.site can be detected as SLOP on the first contact of photon with the retina, I honestly cannot detect https://frame-studio-motion.openai.chatgpt.site and it is giving me depression. The website is basic, but it doesn't feel slop. And I guess that is something.

I'm genuinely sad that what we learned with hard work and sweat, our craft, our identity, our soul; is now something you can buy. I've been in this profession for a long time and now I see people who have absolutely no fucking clue, but lots of money, and they buy all these agents and make things that work (way more broken, with absolutely shit quality), but they work and so they brag about their creations to me all day long, and man that makes me feel like a total loser.

I spent decades trying to master media theory, language design, computer graphics, compiler design, rewriting systems, mathematics, logic, build systems, graphs, data-flow systems, making GUI kits, layout systems, ... all to make a better system for thinking, and now the whole idea of thinking is outsourced (as altman says "sold as utility by the meter"). I need to become an addict or something and be wasted. This is not a life.

Add WYSIWYG site builders to the list of businesses on the chopping block.

Been using it for a while. Very good experience so far. Maybe even better than claude or replit

I’d be firing my entire marketing team if this is all they came up with.

Is this better than Claude? Probably not, right?

I haven't used ChatGPT in over a month. I bounce between Grok, Gemini & Claude. Is ChatGPT even worth it.

Grok can do things the other two can't, like read and fetch websites sometimes where Claude and Gemini cannot.

Gemini is just someone to feed javascript to when you want to save on Claude tokens.

If you want a solution that works with any model/harness, try ht-ml.app!

Would be great if all AI slop sites lived under a common namespace...

rip base 44 /wix

wow there goes lovable's moat

geocities vibes?

Could you just be an API to serve intelligence instead of moving into the app layer and putting your clients out of business. How much wealth and power do you need to accumulate seriously?

another easily blockable domain at least

If you're wondering why OpenAI's models seem to be struggling to stay ahead of Anthropic and are falling further behind, I think it's because of side quests like this.

They have dots, they had Sora, so many other things that take away attention from just having the best model. There are already a bazillion ways to do this. Sure, the integration's nice, but it's just not needed.
