A colleague and I were talking the other day about why I don't really create content about drag-and-drop, low-code platforms. I'm very opinionated on this topic. While these tools have an amazing sales pitch, my long years in this industry have taught me that their promise is mostly a fantasy. For all the slick demos and claims of democratizing development, they often create more problems than they solve.
The Beautiful Lie of the "Happy Path"
The biggest problem with low-code platforms is that their demos only ever show you the "happy path." This is the perfect, sterile scenario where the user does everything exactly right, the data is flawless, and no weird, unexpected things ever happen.
But the real world is anything but a happy path. It's a messy, chaotic place full of edge cases. What happens when a user uploads the wrong file type? Or when an external API you're connected to suddenly goes down?
That's where the beautiful drag-and-drop interface begins to crumble. To handle these real-world scenarios, you inevitably have to write code. Suddenly, you're right back where you started, only now you’re trying to shoehorn custom logic into a system that was fundamentally designed to hide it from you. It feels like trying to fix a car's engine through the glove box.
The Nightmare of Hidden Code
This leads to the next big headache: your UI and the actual logic underneath it get out of sync. You have this clean-looking visual flow, but it's lying to you. It doesn't show the custom scripts, the workarounds, and the emergency patches you’ve had to bolt onto the components.
Imagine a new developer joining the team. They look at the drag-and-drop interface and think, "Oh, this is simple!" But they have no idea about the tangled web of custom code lurking just beneath the surface. This "black box" operation makes the application incredibly difficult to debug and maintain. What you see is definitely not what you get, and that’s a recipe for disaster.
Trapped in the Past: The Perils of Vendor Lock-In
Now, let's talk about the long game. What happens in five, ten, or even twenty years? In my experience, I have yet to see a company handle the lifecycle of these applications well.
You often get stuck with two terrible options:
You’re chained to a legacy UI because that’s the version the original drag-and-drop system supports. It’s ancient, clunky, and can’t handle modern needs, but you can't leave.
You trust the vendor's "migration tool" to move to their latest version. These tools are often faulty and almost never account for the custom code you wrote for those edge cases. Your application breaks, and you’re left picking up the pieces.
This is what we call vendor lock-in. Because most of these platforms don't give you access to the underlying source code, it's almost impossible to pack up your application and move it somewhere else. You're stuck in their ecosystem, and the cost of leaving—in time, money, and sheer frustration is just too high.
The New Wave of AI Tools: Are We Just Going Backwards?
But wait," I hear you say. "What about the new, developer-focused tools for AI and automation? Things like n8n, the new AgentKit from OpenAI, or even some of the agent-building tools from Google? They use visual, node-based interfaces. Isn't that the future?"
I would question that. In fact, I believe it's a dangerous regression, dressing up old problems in the shiny new clothes of AI.
The core issue hasn't changed; it has just moved from the front-end to the back-end. Instead of abstracting away UI components, we are now abstracting away the logic of AI agents and their calls to LLMs. Each node on the canvas looks clean, but it can hide a mountain of complex, custom code.
Yes, for a new developer or someone looking for a quick win, this visual approach provides a clear path to building a simple workflow. In the short term, everything feels awesome. But this isn't an evolution; it's history repeating itself. We're so enamored with the power of AI agents that we're immediately reaching for the same flawed visual abstractions that have failed us before. We are simply creating the legacy maintenance problems of tomorrow, today.
The Bottom Line: A Developer's Crossroads
So, where does this leave us?
Here's my hot take: as AI gets better at understanding our intentions and writing clean, efficient code, the need for that restrictive drag-and-drop layer will finally disappear. Why would a developer want to be constrained by a visual builder when they can just tell an AI what they want to build and have it generate the code for them?
This is the true power of AI-native development. We won't lose the benefits of visualization; we'll enhance them. Imagine an LLM that not only generates the code but can also create an interactive architecture diagram from that code on the fly. Visualization becomes a feature of the code, not a cage it's trapped in.
This opens up a much more interesting question for our industry: How do we, as developers, build the tools that solve the original problem in a better way? How can we leverage AI to make coding itself more accessible, without the pitfalls of vendor lock-in and hidden technical debt?
The future isn't about hiding code behind drag-and-drop boxes. It's about creating intelligent tools that help people write better code, faster. It’s about turning a developer’s idea into a functional, robust application with as little friction as possible.
So, the next time you see a perfect low-code demo, remember the messy reality behind the curtain. But also, get excited. We're on the verge of a new era where the best development tool isn't a restrictive UI—it's a conversation. And as the creators of these new tools, we won't need a "happy path," because we'll have the power to build a road to wherever we need to go.

I agree, while low-code tools can be a great jumping off point for architecting out a potential solution, their limitations and the hacky ways you have to work around them typically cause more problems than they solve. One thing that I do see value in is these as a starting point for generating code. If I could export my low-code agent as, for example, an ADK agent in code: it'd be a great starting point for developing out my customizations and truly making it my own and going beyond the application constraints.
I haven't used a tool that did this effectively (after all, on the back-end this the code these apps run isn't typically equivelent to something a human would typically write) but it is more the direction I'd like to see these kinds of systems go.
I'm ok with it being a starting point or even a tool to learn. Having a way to visualize things and guardrails of available functionality is good, but it should not be a dependable piece of your software solution. :)
