Build vs Buy: You Don't Need Another Side Project

There is a seductive myth in the indie developer community: the belief that true ownership and control require writing every line of code yourself. We see tutorials glorifying custom-built authentication systems, homegrown analytics dashboards, and self-hosted feature flag solutions. But there is a counter-narrative that often goes unspoken—the most profitable tools are frequently assembled from wonderfully boring, existing solutions.

Consider the humble implementation of feature flags in a .NET application. The professional, high-efficiency answer is rarely "write a custom key-value store and UI." It is to install Microsoft.FeatureManagement, configure a few entries in appsettings.json, and move on. This approach isn't a compromise; it's a strategic decision to prioritize business logic over infrastructure overhead. When you strip away the ego-driven desire to build, you uncover the raw efficiency of composition.

The AI Paradox: More Code, Less Value

The current wave of AI coding assistants has paradoxically intensified the temptation to build rather than buy. Because generating code has become trivially easy, developers often default to crafting custom solutions for problems that already have elegant, battle-tested answers. However, accessibility to code generation does not equate to value creation. In fact, it often creates the opposite effect: a flood of marginal, reinvented wheels that distract from the core product value.

This phenomenon separates those who ship and monetize from those who remain stuck in perpetual development hell. The differentiator is no longer technical capability—it is the discipline of restraint. Knowing when *not* to write code is now a more critical skill than knowing how to architect it from scratch.

The Three-Question Filter

To combat the urge to reinvent, apply a strict triage framework before writing a single line of implementation:

1. Is there an open-source solution? Check GitHub, NuGet, or npm. If a robust library exists with active maintenance, use it.
2. Is there a SaaS product? Can you solve this for $29/month instead of 40 hours of dev time?
3. What is the core value of building it myself? Be brutally honest. Is this feature a competitive advantage, or just an operational necessity? If it doesn't directly contribute to your unique value proposition, skip it.

If the first two questions yield adequate results, the third question should almost always be a non-starter. Only when existing solutions fail to address your specific differentiation or scaling needs should you consider building custom.

Your Time Is Your Scarcest Asset

I have watched talented developers spend three months building "a better version" of an existing tool, only to launch into a market saturated with ten superior alternatives. This isn't a criticism of their engineering skills; it's a cautionary tale about opportunity cost. That same time invested in marketing, user research, or refining the core product could have been the difference between a stalled project and a profitable one.

The rule is simple but difficult to follow: buy first, use second, build last. This hierarchy protects your most valuable resource—your time—from being diluted by low-leverage tasks. In the indie landscape, survival and success belong to those who assemble powerful tools from boring parts, leaving them free to focus on what actually matters: the problem they are solving for their users.
