When to Reinvent the Wheel — and When to Just “Borrow” One

Let’s be honest — every developer has had that “I can build this better myself” moment. You’re working on a project, you find a library or tool that almost does what you need… but not quite. And then the inner voice whispers: “Omo, let’s just build our own. How hard can it be?” Before you know it, three weeks later, you’ve built half a wheel, no steering, and your boss is asking for updates. This dilemma is one that many tech teams face: do you use an existing solution, or do you build something new from scratch? Let’s talk about when to reinvent the wheel — and when to just grease the one that’s already rolling. When It’s Okay to Reinvent the Wheel Sometimes, building your own tech solution makes perfect sense. Here’s when: 1. Your Needs Are Truly Unique If you’re solving a problem that no existing tool handles well — like integrating local payment systems or custom data workflows — then a custom solution might be the way to go. Real talk: global APIs won’t always understand the specific needs of your environment the way you do. 2. You Need Full Control (or Security Is Non-Negotiable) If your application handles sensitive data such as government records, financial transactions, or health information, depending on third-party systems can be risky. Owning your stack gives you full control and ensures you can monitor, secure, and optimize every component. 3. You’re Building a Core Business Advantage If the tool or feature is the very thing that differentiates your product or company, don’t outsource it. For example, if your startup’s main value lies in a proprietary algorithm or feature, you shouldn’t rely on someone else’s version. That’s like letting your competitor choose your game plan. When You Should Not Reinvent the Wheel Now, sometimes the smartest move is to use what’s already out there. 1. Time Is of the Essence If the deadline is tight, don’t waste time rebuilding something that already exists and works well. Use a proven tool, deliver your project, and improve it later. 2. Maintenance Will Be a Nightmare Every custom-built solution requires continuous maintenance, bug fixes, and documentation. If your team doesn’t have the capacity to handle long-term upkeep, it’s better to rely on an established, well-supported tool. 3. The Tool Is a Commodity Not every part of your system has to be unique. Authentication, hosting, form handling, or data visualization are often best handled with existing frameworks and platforms. Save your creative energy for the parts that truly set your product apart. Factors to Consider Before You Decide Here’s a quick checklist before you roll out that “we’ll build it ourselves” plan: A Real-Life Example A while back, our team had just a few weeks to deploy a survey data management system for a World Bank project. The goal was to collect and manage field data from multiple regions efficiently. We initially thought about building our own platform from scratch, but after assessing the timeline and project requirements, it became clear that time was not on our side. Going through the full development life cycle — design, coding, QA, and testing — would have delayed the project. Instead, we opted for a trusted, ready-made tool called KoboToolbox, which is widely used by international organizations for survey data collection and management. It had all the features we needed: mobile data capture, offline capabilities, analytics, and centralized management. By choosing KoboToolbox, we were able to deploy quickly, meet the project timeline, and focus our energy on customization and data quality rather than reinventing an entire system. Sometimes, the smartest engineering move is knowing when not to build. Over to You Have you ever spent weeks building something, only to discover there was already a tool that did it better?

When do you think it’s worth reinventing the wheel — and when is it smarter to just borrow one that’s already rolling?
