The vibe-coding hangover.

In 2025 the most repeated demo in software went like this: you typed a sentence describing an app, and a few minutes later a working app appeared in your browser, database and deploy URL included. Lovable and Bolt.new built their whole products around that moment. Early Replit Agent put a cloud development environment behind it. People started calling it vibe coding, and for a stretch of the year it felt like the ground was moving.

I spent real time with these tools, partly as competitive research and partly because the demo is fun. This post is about what happens after the demo, because the industry is now living through the hangover from that particular party, and I think the hangover is more instructive than the party was.

The demos were not fake

The wave was earned. Compressing "I have an idea" into "I have a running app" is a real technical achievement, and the teams behind Lovable and Bolt.new deserve respect for making it feel ordinary. So does Replit for wrapping the same move in an actual cloud environment rather than a toy sandbox. A lot of people shipped their first working software last year because these tools existed. Nothing below takes that away.

The wave also settled an argument. Nobody serious still disputes that models can write code. But whether a model can produce a working app was never the interesting question. The interesting question is whether anyone can keep working on that app in week six.

Week six is where it dies

Here is the pattern I hit repeatedly, and the one I hear from nearly everyone who pushed a prompt-to-app build past its demo. The first session is euphoric. The second is fine. Around the fifth, you ask for a small change, the tool regenerates a large chunk of the app to make it, and something unrelated quietly breaks. You ask for a fix. The fix breaks a second thing. Now you are negotiating with a system that has no idea why the code looks the way it does, because it never knew. Every prompt becomes a fresh roll of the dice across the whole project, weighted by whatever happened to survive into the context window.

The concrete versions are familiar to anyone who has been through it. The login flow that worked on Tuesday returns a blank page on Friday because a later generation renamed a route nothing else knew about. The restyle that fixed the page you asked about and subtly changed spacing on the pages you did not. Several of my own test builds ended the same way: a working demo that drifted for a string of sessions, then a rewrite in a real editor.

The failure is structural, and better models alone will not fix it, because one-shot generation fails at real software in a specific, repeatable way: no plan, no structure, no memory of intent.

No plan means architecture happens token by token. The model commits to a data model in the first minute of generation and meets the requirement that invalidates it twenty minutes later. When a person builds this way we call it improvising in production, and the industry spent decades learning to stop.

The missing structure shows up as unlimited blast radius. When the unit of work is the whole app, a request to move a button can touch the schema. There is no boundary that says this change may modify these files and nothing else, so the only integrity guarantee you have is luck.

And because nothing remembers intent, the decisions evaporate. Code is a record of decisions, and in a one-shot tool the decisions live only in a chat scroll. Ask why sessions are handled the way they are and there is no artifact to consult. The tool does not know. After enough sessions, neither do you.

Checkpoints are an admission

Replit deserves a closer look here, because checkpoints are the most practical feature in the category. Replit Agent 3 lets you roll a project back to a known-good state when a generation goes sideways. Read that as the vendor telling you, correctly, that generations go sideways often enough to justify an undo button for your entire app. I like checkpoints. But a rollback is a save point, not an explanation. It restores the past without telling you what the present did wrong. Undo is not review.

The editor agents got further down this road. Cursor built on VS Code precisely so the agent would work where code already lives, and its changes land in a real repository where the diff is the native unit of change. Claude Code takes the same posture in the terminal, and Devin moves the autonomy into a cloud IDE. These tools take more care with maintenance than any one-shot builder, and I use them. Their limit is a different one: the repo holds the code while you hold the plan in your head. The editor knows what you typed most recently, not what the software is supposed to become.

The rest of the field is pointing the same direction. Anthropic's Claude Cowork preview in January applied the agentic core of Claude Code to ordinary desktop work, reading and editing real files in folders you choose. Manus now has a desktop app of its own. Agents everywhere are converging on persistent, inspectable artifacts. The one-shot builders are the outlier, not the future.

What a structured alternative has to look like

Each failure mode implies a requirement. Put them together and the shape of the tool stops being mysterious.

The plan is an artifact

Before any code exists, the tool should show you what it intends to build, in pieces you can edit. For a small product that plan might be a dozen pieces: the data model, the pages that sit on it, the integrations you forgot you needed, the deploy target. If the plan is wrong you fix the plan, which is cheap, rather than the code, which is not. The plan is also where scope gets negotiated. The moment to say "no admin panel yet" is before the admin panel exists.

Builds are sectioned

Each piece of the plan builds separately, so blast radius stays local. Regenerating the auth section cannot quietly rewrite billing. When something breaks, you know which section owns the break, and fixing it does not put the rest of the app back on the table.

Every change is a diff

Nothing mutates silently. Changes arrive as diffs you read and accept, which is the same contract version control has enforced on human programmers for decades, for the same reason. Reviewing a scoped diff takes minutes. Re-auditing an app that changed underneath you takes days, which is why nobody does it, which is how the drift compounds.

Intent survives the session

The plan stays attached to the code it produced. Six weeks later the why is still on the surface, so a change request gets evaluated against what the software is meant to be rather than against whatever text happens to sit in the context window that day.

And beneath all four: real work starts from existing material. A tool that only accepts a blank prompt is a demo machine by construction. It has to ingest the repository you already have and the design your designer already made, because almost nothing worth maintaining starts from zero.

How we built it

Project Canvas is OMEGA's version of this, and I will describe it as mechanism rather than pitch, since the argument of this post and the design of the product are the same argument.

You start from an idea or from existing material: files, a local folder, a git repo, a Figma link. Canvas turns the idea into a plan drawn as nodes, and the nodes are the contract. You can rename or delete them and add the piece the plan missed, all before a line of code exists. The build then runs section by section against those nodes, producing real code you can open rather than a black-box bundle. A live preview runs beside the build, so you are looking at the actual app instead of a rendering of one. Every change the system makes lands as a diff you review. A terminal sits on the same surface for the moments you want your own hands on the project, and deploy is the last step of the same flow rather than an export to somewhere else.

The visual half gets the same treatment. Design Studio is a full AI-guided UI/UX studio with an infinite canvas and real design systems, and its copilot proposes edits that are reviewed and undoable rather than applied on faith. A design made there bridges directly into a Canvas build instead of being re-described to a model in prose, which is where a lot of one-shot fidelity goes to die.

Under both sits the same Neural-Fractal Agentic AI™ (NFA) engine that runs the rest of OMEGA: work decomposed into small scoped units, each holding only the context it needs. Sectioned builds are that idea applied to code, and I wrote about the engine itself in an earlier post.

The cost: plan-first is slower to first pixel, and it loses demo contests. Reading diffs is work, and some people will not want to do it. If you need a disposable prototype by tonight, Lovable or Bolt will get you there faster, and I mean that respectfully; disposable prototypes are a legitimate category. My objection is to selling disposable output as a product you can run a business on.

The hangover is the lesson

The 2025 wave proved the demand beyond argument. An enormous number of people want to make software and were never going to learn to program first. The correction now under way does not kill AI app building. It moves the bar from minute one to week six.

Software is decisions plus code. Tools that discard the decisions produce code nobody can keep, no matter how good the models get. Demos age in minutes; products age in years. Build with something that plans first and shows you its diffs, whoever makes it. Ours is Project Canvas, and the rest of the details live on our pricing page.
