Vibe Coding Platforms Have a Retention Problem Nobody’s Talking About
Lovable hit $100M ARR faster than almost any B2B SaaS company in history. Bolt was at $40M ARR by March 2025. Cursor raised at a $9.9B valuation with a million daily active users. The vibe coding wave looked, for a moment, like one of the cleanest product-market fit stories in recent memory.
Then traffic fell off a cliff. Lovable dropped ~40% from its summer peak. Vercel’s v0 fell 64%. Bolt slid 27%. The platforms that were supposed to democratize software development suddenly had a very traditional problem: people were signing up and leaving.
Everyone’s blamed it on the novelty factor. “It was hype.” “Users got what they needed and moved on.” And some of that is probably true.
But there’s a more specific problem underneath the numbers, one that’s structural to how vibe coding works, and I havent seen anyone talk about it honestly. So here it is.
The wow moment is real. That’s actually the problem.
Vibe coding delivered something genuinely new in 2024 and 2025: non-technical founders, indie hackers, and domain experts who’d never shipped software in their lives discovered they could describe what they wanted and watch working code appear. In an afternoon. Deploy by dinner.
That wow moment is legitimately powerful. I’ve watched people tear up a little the first time it worked for them. After years of being told “you need to learn to code” or “you need to hire a developer,” suddenly the gap between idea and shipped product collapsed to almost nothing.
That wow moment drove millions of signups. And it’s real. It’s not manufactured excitement.
But here’s what nobody says out loud: the wow moment lives in a very specific slice of the project lifecycle. It lives in the first 20%.
Clean requirements. Simple features. Greenfield scope. “Build me a landing page.” “Create a login form.” “Add a dashboard with these three charts.” The AI is genuinely magical here. You describe it, it appears, it mostly works. You feel like a wizard.

The problem is that nobody lives in the first 20% forever.
The retention cliff nobody’s measuring
Projects grow. Requirements get messier. Features interact with other features. State management gets complicated. The app that was clean and clear at week one starts to accumulate technical debt, edge cases, weird bugs where two things that worked separately break when they’re combined.
And then the user types something like: “why is my auth state not persisting across page refreshes when the user has a slow connection?”
The same AI that was effortlessly building forms and dashboards now starts to struggle. It gives an answer. The user tries it. It doesn’t quite work. They explain the error. The AI gives another answer. They try it. A different thing breaks. The conversation that used to feel like collaboration starts to feel like debugging with someone who cant actually see your codebase.
This is the complexity cliff. And it’s the primary driver of vibe coding churn.
We’ve looked at conversation patterns across AI coding products and the arc is remarkably consistent. Session count peaks 3-4 weeks in for the typical vibe coding user. Then the nature of the conversations shifts in a very specific way: the user moves from “build X” requests to “fix this error” loops. And then, critically, the same error or a closely related error starts appearing across multiple consecutive sessions. The user is stuck in a loop the AI cant break them out of.
That error loop rate, the same class of problem recurring across sessions without resolution, spikes right before churn. It’s the clearest leading indicator in the data.
And here’s the brutal part: users who cross the complexity cliff without support almost never come back to the same platform. They don’t give it another chance. They either find a developer, they try a different tool, or they quietly abandon the project. The platform that failed them at the cliff doesn’t get a second shot.
Not all churn is equal. Most platforms are solving for the wrong segment.
Here’s where it gets more nuanced. Not every user who leaves is the same. There are roughly three types of vibe coders, and they have very different retention trajectories.
The MVP Builder comes in with one specific thing they want to ship. A landing page. A simple internal tool. A prototype for a pitch. They use vibe coding, ship the thing, and naturally taper off because they got what they came for. Their usage arc looks like churn but it’s actually completion. This person leaving isn’t a problem, it’s a successful outcome.
The Serious Builder wants to build a real product. They’re in it for the long haul. They hit the complexity cliff too, but they have enough technical intuition, enough stubbornness, or enough of a support system to push through it. They get past the hard parts through some combination of AI help and their own debugging. These are your best long-term users if you support them well through the cliff. They become power users, they evangelize, they pay for higher tiers.
The Overwhelmed Experimenter is the biggest segment and the hardest to serve. They come in with an ambitious idea. Something real, something that matters to them. They have the Serious Builder’s ambition but without the technical background to fall back on when the AI starts failing. They hit complexity earlier, they dont know how to diagnose what’s going wrong, and they get frustrated fast. High volume. Low LTV. Dominant churn segment.

Most vibe coding platforms have optimized their entire product experience for the MVP Builder. The showcase is full of “look what I built in an afternoon” demos. Onboarding is frictionless. The first session is carefully designed to get to the wow moment as fast as possible.
Which is fine, the wow moment is real. But it means the Serious Builder and the Overwhelmed Experimenter, who have very different needs once complexity sets in, are being served by a product experience that wasnt built for them. The platform solves for acquisition by nailing the first session. It doesnt solve for retention by nailing the tenth session.
What the platforms that are actually winning are doing differently
The good news is that the complexity cliff isn’t unsolvable. Some platforms are starting to build real solutions around it. Here’s what the approaches that actually work have in common.
Complexity detection. The best platforms aren’t waiting for users to hit the cliff and fail. They’re watching for signals that a project is entering the complexity zone: error loop frequency, session depth changes, topic shift patterns (the shift from “build” requests to “fix” requests), context window strain. When those signals fire, the product changes mode. More guided support. Smarter error diagnosis. Tighter context management. The user doesn’t have to know the product shifted gears. They just stop hitting walls as hard.
Conversation-native debugging. The traditional vibe coding loop is: generate code, user runs code, user pastes error back into chat, AI suggests fix, repeat. That loop is fine for simple errors. It breaks down badly for complex multi-session bugs where the AI has lost context about what’s been tried already. The platforms starting to win here build error diagnosis directly into the conversation flow. The AI isn’t just responding to the current message. It’s reasoning about the history of what’s been attempted and what’s failed.
Project memory. This one sounds obvious but very few platforms do it well. As a project grows in complexity, the AI’s ability to give coherent help depends on how much of the project context it’s carrying. Most platforms handle this poorly. Each new session is semi-fresh. The AI that helped you build auth last week doesn’t reliably remember the decisions made about your data model the week before. Persistent project memory isn’t a nice-to-have. It’s the core technical requirement for supporting users past the complexity cliff.
Smart handoff. The most honest platforms know when the AI is failing and surface human help or community resources proactively. Not as a failure state, but as a natural part of the product experience. “This looks like a complex auth issue, here’s a community thread from someone who solved something similar” is a much better experience than watching the AI hallucinate three different wrong answers in a row.
The metric that actually separates the platforms that will win
Forget DAU. Forget D30 retention as a raw number. Forget even revenue as a short-term signal.
The metric that separates vibe coding platforms that have a real business from ones that are riding an acquisition wave is what I’d call complexity threshold retention. Of the users who reach project complexity X, measurable via error loop frequency, session depth changes, and topic shift from build to fix, what percentage continue building versus churn?
You can operationalize project complexity X pretty simply. Look for the inflection point in your conversation data where the request type shifts from creation to debugging, where error-related messages start appearing in sessions, where the same error class shows up across multiple sessions without resolution. That inflection point is the complexity threshold. It’s not the same for every user, but it’s identifiable in the data.
A platform that loses 80% of users who hit that threshold has an acquisition business, not a retention business. A platform that retains 60% of those users has something with real long-term economics.
Right now, most platforms dont even know what their complexity threshold retention rate is. They’re not segmenting churn by where in the project lifecycle it happens. They’re seeing a cohort curve and trying to optimize onboarding.
That’s the wrong lever.

The intervention has to happen at the cliff, not at signup. Better onboarding doesn’t help you if the user makes it through onboarding and then churns at week four because the AI got stuck in an error loop.
What this means if you’re building a vibe coding platform
The category isn’t broken. The underlying insight, that non-technical people can now ship real software, is real and durable. But the first generation of vibe coding products were built to demonstrate that insight. The next generation has to be built to sustain it.
That means investing in complexity detection and response mode adaptation. It means taking project memory seriously as a technical problem. It means segmenting your users by project complexity, not just by session count, and building separate support experiences for the Serious Builder and the Overwhelmed Experimenter.
And it means tracking conversation patterns at the session level, not just aggregate metrics. The signal that a user is about to churn is in the way their conversations are changing, the shift from building to fixing, the error loops, the sessions getting shorter and more desperate, not in their DAU contribution.
At Agnost, we’ve been tracking these patterns across conversational AI products for a while. The error loop rate and the build-to-fix topic shift are two of the clearest leading churn indicators we see across any category of AI product. If you’re running a vibe coding platform and you’re not tracking these at the individual user level, you’re flying blind on the exact moment when your users decide whether to stay or leave.
The complexity cliff is real. The question is whether you see it coming.
Wrapping it up
Vibe coding had a genuine product insight at its core. Non-technical people can now ship software. That’s real. That’s not going away. But insight alone doesn’t make a business, retention does.
The structural retention problem in vibe coding is the complexity cliff: the point where projects outgrow what the current generation of AI can handle cleanly, and where users without technical backgrounds have no fallback. Most platforms built great first-session experiences and weak tenth-session experiences. The churn data is a direct consequence of that.
The platforms that figure out complexity threshold retention, the percentage of users who survive the cliff and keep building, are the ones that turn vibe coding from a viral demo category into a durable software development platform. That’s the game worth playing.
If you want to track where your users are in this arc, the conversation data already has the answer. You just have to be looking at it the right way. That’s what we built Agnost for.
^ you, after instrumenting complexity threshold retention and finally knowing exactly where and why your users are churning
TL;DR: Vibe coding platforms churn because the AI that’s magical for the first 20% of a project breaks down as complexity grows. That inflection point, the complexity cliff, is the real churn event. Platforms that can detect it early, adapt their support model, and track “complexity threshold retention” are the ones that survive past the hype cycle.
