A new open source agent called AgentSwift recently hit Show HN. It builds iOS apps. That's it. No web, no backend, no database. Narrow on purpose.

The comments loved it and I get why. There's something nice about a tool that does one thing without pretending to be everything. But it surfaced a question I hear a lot from people building their first app: when do you want a specialized agent, and when do you want a full platform?

It depends on what you're actually trying to ship.

Specialists go deep

If your scope is genuinely narrow, a specialist usually beats a generalist. AgentSwift is tuned for iOS. It knows SwiftUI patterns, App Store quirks, the weird stuff Apple does. A general AI knows less about that than something purpose-built.

Same logic applies elsewhere. Cursor is great if you want to write code yourself. Lovable is decent for quick web prototypes. Bolt is fine for a one-off demo.

If you want a thing, and only that thing, pick the tool built for it.

Platforms ship businesses

Most people I talk to start narrow because their first idea sounds simple. "I just want an iOS app." "I just need a landing page." Then reality lands.

You need a database. You need auth. You need a Korean payment integration because that's where your customers are. You need a place for a stakeholder to log in and review without breaking anything. You need analytics. You need to ship updates without rewiring half the stack every time.

That's not a specialist problem. That's a platform problem.

This is the gap we kept seeing while building DontCode. Nobody actually wants an "iOS generator" or a "page generator." They want a business. The app is one piece of it. The hard part is the auth, the payments, the team access, the deployment, the analytics, the iteration loop after launch.

So our AI is fine-tuned for app building, not a wrapper around generic Claude. The infrastructure is pre-configured, you never touch it. KakaoPay and Toss work out of the box for Korean teams. Roles let your legal reviewer or investor log in without touching the editor. When you're ready, you ship to a custom domain in one click.

How to actually choose

Weekend hack, portfolio piece, something genuinely scoped to one platform? Try the specialist. AgentSwift looks fun for that.

Running a business, getting paid, working with a team, shipping to Korean customers? Pick a platform.

The mistake is using a specialist for a platform problem and ending up duct taping six tools together. I've watched that movie. It does not end well.

The other thing worth saying: a specialist agent is a feature, not a company. Most of these single-purpose builders will get absorbed into bigger platforms within a year. So if you're picking a tool for a real business, picking the platform that already includes the workflow tends to age better than betting on a one-trick repo that may or may not still be maintained next quarter.

If the platform side is more your speed, we're at DontCode, and there's more on this stuff over at the blog.
