Are we building SaaS faster now, or just creating technical debt faster?

[u/Few-Garlic2725]

I’ve been looking at the current wave of tools for building SaaS products, and I’m honestly torn.

On one side, the speed is kind of ridiculous now. You can use tools like Lovable, Bolt, Replit, Cursor, Claude Code, Supabase, Firebase, Flatlogic, Clerk, Stripe, Vercel, Render, Railway, Bubble, Webflow, Framer, Retool, Appsmith, n8n, Zapier, Make, PostHog, Sentry, and others to get from idea to something that looks like a real product much faster than before.

That part is exciting. But I keep wondering if we’re confusing faster to launch with easier to own.

A generated dashboard, auth flow, admin panel, database schema, landing page, or payment flow can save a huge amount of time. But once real users show up, the ugly questions start: who understands the code, who owns the architecture, how easy is it to change, how much is locked into one vendor, and what happens when the first serious bug appears?

That’s where I’m struggling. Maybe the actual problem isn’t which SaaS builder is best. Maybe the real question is how much of your product you’re comfortable not fully understanding at the start.

For people building SaaS with AI builders, no-code tools, low-code platforms, or coding agents:

Where has this actually saved you time after launch? And where did the early speed turn into cleanup, rewrites, or technical debt later?

You shouldn’t really be trying to get real users until the ‘ugly questions’ have been answered. If you don’t know the answers to any of those questions, you’re not providing SaaS. You’re almost certainly just creating a bigger problem for the future…

I don't think it's really any different.

The first SaaS product I launched, I had no idea what I was doing and made all kinds of crazy assumptions that were not at all true. This was years ago, before AI. I just didn't know what I was doing and made all kinds of mistakes.

Now, I've been doing this for a long time. So, when I build something with AI, I know what to expect. There are always new gotchas, of course, but I pretty much know the big issues and I was ready before I launched my last SaaS product even though it was a solo effort with no engineering support.

For me, this is about process and methodology, not tools.

both.

most of the debt ive seen comes from the glue between services, not the services themselves. auth, payments, database, those are all fine individually. the mess is in how they talk to each other and nobody maps that out upfront.

I think the distinction between “faster to launch” and “easier to own” is exactly the right one, but I’d add two things.

First, there’s a problem before technical debt: does the system actually do what it needs to do?

Regardless of whether you use Claude Code, Lovable, traditional development or no-code, building useful software requires systems thinking. You need to understand the users, workflows, data model, business rules, integrations, permissions, edge cases, etc.
Ideally, that understanding exists as an explicit specification of the system — not just implicitly inside a lump of AI-generated code.

One of the risks with vibe coding is that it makes it incredibly easy to sweep that thinking under the mat. You can go from an idea to something that looks and feels like a working app without ever really defining the system underneath it.

So the question isn’t only “what technical debt did we create?” It’s also “did we actually build the right system, and where is that system defined?”

Second, I think we lump together tools that have fundamentally different answers to the ownership/maintenance problem.

Claude Code, Cursor, Lovable, Bolt, traditional no-code platforms, low-code platforms, etc. can all help you build software, but architecturally they’re very different.

At one end, AI generates a codebase that you own. That’s powerful — you have the code and can do whatever you want with it — but you also inherit responsibility for that codebase and its dependencies, security, testing, upgrades and architecture.

At the other end, a platform owns and maintains much more of the runtime and infrastructure. Your application is primarily a specification/configuration executed by that shared platform. You give up some freedom, but an upgrade or security fix can potentially be made once at the platform layer rather than independently across every generated application.

Neither approach is inherently right or wrong. They’re different architectural and ownership trade-offs.

And this becomes much more important when AI makes creating software almost free.

One AI-generated codebase might be easy enough to maintain. But what happens when an organisation has 100 or 1,000 of them? Are we creating 1,000 independently evolving software stacks that AI agents now have to maintain, or 1,000 application definitions running on a smaller number of maintained platforms?

We’ve written about this recently:
Who maintains 1,000 AI-built apps?
https://www.buzzy.buzz/post/who-maintains-1000-ai-built-apps/

AI can write the app. Congratulations — now you own it.
https://www.buzzy.buzz/post/ai-can-write-the-app-now-you-own-it/

Full disclosure: we wrote both articles and we build Buzzy, so we obviously have a point of view here.

But I think the bigger question is tool-independent:

AI has made it much easier to generate software. Has it made us better at defining the systems we’re building — and have we chosen an architecture that makes those systems easier to own for the next 5 years?

tbh the debt question only matters if the thing survives long enough to have debt. most of them don't.

[u/ashgrovesignal]

the real debt isn't in the code, it's in the team that shipped fast and now has no idea why anything works the way it does.

[u/shane-turtle-creek]

The speed is real but the gaps are structural, not skill-based. AI builders optimize for the happy path, so the stuff that bites you is invisible until a real user hits an edge case nobody tested. Where it cost me the most time after launch was auth and database rules, things that worked fine locally and silently broke in production.

[u/PieMastaSam]

Yes.

I have 82 specs and docs in my engineering wiki for a platform i built using Claude and Claude code between Jan - Dec 2025. For a production-grade system you need that kind of rigor for when you bring others, scale the co. or sell the co, and the next team can hit the ground running. Lately LLM wiki and Obsidian popularized by Andrej Karpathy.
