AI app build is easy. Distribution is hard. Here's the part most takes miss.
The build step compressed from weeks to minutes. The cost of getting strangers to open your app didn't move. And most AI builders quietly added a new friction tax at the handoff between your URL and the next person opening it.
Direct answer, verified 2026-05-11
AI compressed the build step from weeks to minutes. The work of getting strangers to open your app (writing a post, recording a demo, replying to comments, getting one person to forward it to another) is the same as it was in 2018. On top of that, most AI builders re-introduced new friction (signup walls, install gates, expired sandboxes) at the URL-to-eyeball handoff that simply did not exist when you sent your friend an HTML file. That stack is what people mean by “distribution is hard.”
Verified against the public discussion on startupnotes.eu (May 2026) and the implementation behavior of the mk0r repo (the relevant file paths are quoted below).
The takes you've already read
The standard version of this argument runs as follows. AI changed what an MVP costs to build. It did not change what it takes to actually ship one to real users. Marketing is the same job it was in 2018. Audience is the same job. The build moved from being the slow part of the lap to being the fastest part. Everything downstream of build (going live, getting users, learning from them) stayed where it was. Therefore distribution is the bottleneck.
All of that is true. It is also the easy part of the observation. Every article that ranks for this topic stops there. The harder part, and the part I want to walk through, is that “distribution” is not one thing. It is two things wearing the same coat.
Distribution is two problems, not one
The first problem is the one everyone names: how do strangers find out the app exists. The post, the demo, the launch, the SEO, the cold DM. That is marketing. It is hard, it has always been hard, and AI did not make it easier except at the margin (it can help you write the post a bit faster).
The second problem is downstream of marketing, and almost nobody is pricing it: once a stranger has decided to click your link, how much friction sits between that click and them seeing the app. In 2018 the answer for a hobby project was approximately zero. You sent a friend an HTML file or a URL pointing at a static host, they clicked, the page loaded, they saw the thing. In 2026 with the standard AI app builder stack, the answer is one or more of: a signup wall, a login gate, an install flow, a sandbox that expired three hours ago, a mobile layout the builder never bothered to test, a paywall past N unique viewers, or a wrapper UI that only lets the recipient see your app inside the builder's own dashboard.
That second category is friction tax. It compounds. Each layer is a number, and the numbers multiply. A 50% drop at signup combined with a 50% drop at mobile-broken layout is a 75% loss before marketing even hits the field. Most makers reading the phrase “distribution is hard” assume their job is to get better at marketing. Sometimes the actual job is to stop paying the handoff tax.
“What sits between a click on the share link and the recipient seeing the app, when the link is a public URL on a real domain with no auth in front of it.”
The point of the rest of this article
Run the diagnostic on your own app
Take the share link your AI builder gives you. Open it on a phone, signed out of everything you use, in an incognito or private window. Set a timer on click. Stop the timer when you can actually use the app, not when a loading state finishes but when the first interactive screen is in front of you. If the answer is longer than five seconds, or if at any point between click and screen you saw a signup prompt, a login flow, an install request, or an expired-sandbox message, you have found your handoff tax.
The friction inventory below is what to look for. Each item is a real failure mode I have hit testing share links from AI builders that ranked on Product Hunt in the last twelve months.
Handoff friction inventory
- Signup wall before first paint (you lose 40-60% of mobile clicks here, every time)
- Install a desktop app or browser extension to view (you lose 70%+)
- Login with Google, but Google is blocked in the recipient's browser
- Sandbox URL expired between when you sent it and when they opened it
- Link opens fine, but only inside the builder tool's wrapper UI with a banner
- Mobile-broken layout because the builder targeted desktop demos
- Paywall on output past a certain number of unique viewers
The handoff in 2018 vs 2026
The reason this category of friction is invisible to most discussions is that it was zero a decade ago and nobody clocked when it crept back. The comparison below is honest about both eras. Both 2018 and 2026 are great at specific things. The point is the handoff in 2018 was structurally simpler.
The path from click to first usable screen
You write an HTML file. You drop it on a static host (or DM the file directly). You send the URL. Your friend clicks. The page loads. They see the thing. There is no account, no install, no sandbox TTL, no wrapper UI. There is also no auth, no persistence, no payments, no analytics. The trade is that the thing you shipped is small. The handoff is free.
- 0 walls between click and screen
- No expiration on the URL
- Mobile and desktop both work because HTML
- The thing you can ship is small, that's the trade
The 53 lines that decide whether your link does any of this
mk0r is one bet against the handoff tax. The output of a build session is a URL at <vmId>.mk0r.com. It is a real public subdomain. The recipient clicks. The app loads. No signup, no login, no install, no wrapper. The mechanism is a single file in the open source repo, and it is 53 lines.
The file is src/proxy.ts. It runs as Next.js middleware. When a request hits a host like abc123xyz456789.mk0r.com, the proxy extracts the part before the apex, checks it matches the VM ID regex (15-30 lowercase alphanumeric characters), and rewrites only the hostname to 3000-<vmId>.e2b.app. Path, query, and method pass through untouched. There is no auth check. There is no signup gate. The link works for whoever has it, on whatever device, until the sandbox times out.
The TTL is one hour. It is set as a single constant at src/core/e2b.ts line 33: const E2B_TIMEOUT_MS = 3_600_000; That is the honest trade. Free, no signup, no install, in exchange for a one hour window. It is enough for the moment that actually moves your project, which is showing one specific person the thing while it is fresh in your head. If they react and you want it to live longer, the publish flow at src/app/api/publish/route.ts exists. Most builds never need that step.
Why this is not an argument against marketing
Removing handoff tax does not get you users. Distribution-as-marketing is still its own job, and it is still hard. You still have to write the post, record the demo, reply to the thread, get one person to forward it to another, ship the cold DM that does not feel like a cold DM. None of that gets easier by removing a signup wall.
What removing handoff tax does is preserve the conversion rate your marketing actually earns. If your post is good enough to get a hundred clicks, you want all hundred to see the app, not the thirty-five who survive the wall. The handoff tax is multiplicative against everything upstream. Marketing has to fight the wall on top of fighting attention, and most marketing budgets cannot.
What I'd want you to take from this
Build is easy now. That is real. Distribution is hard. That is also real. But before you accept “distribution is hard” as the full explanation for why your AI app did not move, run the five-second diagnostic. Open your share link on a phone, signed out, incognito. Count the walls. The number you get back is not marketing. It is a structural choice the tool you used made for you. Pick differently.
Want to see the handoff actually go to zero?
Show me what you're building. I'll send you a live mk0r URL with no signup in front of it and we can compare it side by side with what your current builder ships.
Frequently asked questions
Why is distributing an AI built app harder than building it?
Three reasons stacked on top of each other. First, AI compressed the build from weeks to minutes, but the cost of getting strangers to actually open your app did not change. The work of writing a post, recording a demo, replying to comments, getting one person to forward it to another person, that work is the same as it was in 2018. Second, the universe of new AI apps that ship every day is now hundreds of times bigger than the audience for any one of them, so attention per app went down even though every individual app got cheaper to make. Third, and the part most takes skip, most AI builders re-introduced new friction at the handoff between your URL and the next person opening it. Signup walls to view, login gates, install flows, sandboxes that expire before the recipient even reads your DM. None of that existed when you shipped an HTML file to a friend in 2018. It exists now because the AI builder needed an account to attribute usage to. The combination is what people are calling 'distribution is hard.'
Is this just another way of saying 'marketing is hard'?
No. The standard answer to 'distribution is hard' is marketing. Write the post, build the audience, do the Product Hunt launch, learn SEO. All real, all the same as it was a decade ago. But that conversation skips a different category of distribution loss, which is everything that happens between the moment a recipient clicks your link and the moment they actually see your app. If the link forces a signup before the first paint, you lose a chunk of clicks there. If it asks them to install an extension or app, you lose them there. If the sandbox expired three hours ago because the link was passed around DMs overnight, you lose them there. None of that is marketing. It is structural friction that the builder you used decided to add. Marketing can fight a 10% conversion rate at the handoff, but it cannot fight a wall.
What does mk0r actually do differently at this layer?
The output of a build session is a live URL at `<vmId>.mk0r.com`. It is a real public subdomain on the open internet. The recipient does not sign up. They do not install anything. They do not log in. They click the link and the app loads, on whatever device, on the first paint. The file that decides this is `src/proxy.ts` in the open source repo, 53 lines. It checks that the host looks like a VM ID, then rewrites only the hostname to `3000-<vmId>.e2b.app` while preserving path, query, and method. That is the entire mechanism. The trade is honest: the sandbox URL has a one hour TTL set as `E2B_TIMEOUT_MS = 3_600_000` at `src/core/e2b.ts` line 33. If you need the link to live longer than an hour you have to act, but the act is small, and the first hour is enough for the moment that actually moves your project, which is showing one person the thing while it is fresh in your head.
If distribution is the bottleneck, why even bother with build speed at all?
Because build speed changes the shape of what gets attempted. When the build cost was two weeks of nights and weekends, you only built the idea you were already sure of, and you only showed it to people after you were sure it worked. When the build cost is fifteen minutes, you build the idea you are not sure of, and you show it to one person before you have decided whether it is worth working on. That second loop is where most distribution happens for indie projects: one person at a time, in a DM, with a real reaction from a real reader. Build speed is what makes that loop possible. Distribution is what closes it. They are not in competition. They are different stages of the same lap.
Does this mean serious apps don't need real hosting and a real domain?
Real apps with paying users need real hosting, real domains, real auth, real persistence. Nobody is saying otherwise. The argument is about a different stage. The stage between 'I had an idea this morning' and 'I am going to invest a real engineering week in this.' At that stage you do not yet know if the idea is worth a real domain. You want to show it to two people and read their faces. A throwaway public URL with a one hour TTL is exactly the right shape for that stage. When you are sure, mk0r has a path to publish to a custom domain, the request flow lives at `src/app/api/publish/route.ts` and emails the operator to wire the domain. Slow but honest. Most apps never need that step because they never make it through the first stage. The ones that do, do.
What if the AI builder's signup wall is actually making the product better?
Sometimes it is. Auth-gated outputs make sense when the product is collaborative, when there is real state to persist per user, when the builder genuinely needs to know who is hitting the sandbox to bill or to learn. The argument is not that signup is always wrong. The argument is that signup at handoff is a tax, and a lot of products are paying that tax without realizing it costs them anything. Every wall between your URL and the next person opening the app is a number, and that number is usually somewhere between 30 and 80 percent depending on the audience. If the product is at the stage where it needs to attract its first hundred users, paying an 80 percent wall tax is a bad trade no matter how clean the auth flow looks.
How do I actually test this for my own AI built app today?
Open the share link you would send to a stranger, on a phone, signed out of everything, in an incognito window. Time how long it takes from click to first usable screen. If the answer is longer than five seconds, or if there is any signup or install step in between, you have found your distribution friction. That number is not marketing. That number is mechanics. mk0r is one way to remove it. There are others. The point of the article is not to sell you on a specific tool. The point is that this category of friction is real, measurable, and almost nobody is pricing it when they write 'distribution is hard' on Twitter.
