For any software need, organizations now have three realistic paths:
Buy (SaaS): Purchase a commercial product. Fast, supported, predictable costs. But generic, not customizable, ongoing subscription cost.
Build custom (engineering team): Hire or contract engineers to build exactly what's needed. Fully customizable, owned. But expensive, slow, ongoing maintenance burden.
Vibe code: Use AI tools to build a custom solution quickly and cheaply. Between buy and build in cost, speed, and ownership. Limited to appropriate scope.
Use a SaaS product when: - The problem is common and well-served by existing tools - You need enterprise-grade security, reliability, and support - You want to avoid maintenance responsibility - The product fits your needs at 80%+ without modification
Use vibe coding when: - The need is specific to your workflow and not well-served by generic tools - The stakes are low (internal use, personal use, or controlled team use) - Speed and customization matter more than long-term support - The task is within the capability envelope (personal tools, prototypes, automations)
Use a development team when: - The software will be customer-facing with real data and reliability requirements - Security or compliance requirements apply - Long-term maintenance and evolution are planned - The business model depends on the software as a core product
The most pragmatic organizations combine all three: - Use SaaS for commodity needs - Use vibe coding for internal tools and prototypes - Reserve engineering investment for genuine product differentiators
Vibe coding is at its most valuable as a prototyping and internal tooling layer — fast, cheap, good enough for low-stakes use — rather than as a replacement for engineering on high-stakes systems.
