Why DIY internal tools collapse — and what CIOs & CTOs should do instead

Building internal tools yourself can seem like the smart path. You stay in control, avoid vendor lock-in, and skip lengthy procurement cycles.

‍

But beneath the surface, DIY tooling often leads to a brittle, unsustainable foundation—ultimately leaving you with a tangle of tech debt, patchwork integrations, and painful maintenance cycles.

‍

Below we break down why DIY internal tooling is a house of cards, and why enterprises need a foundation purpose-built for secure, scalable, and production-grade solutions.

The hidden costs of DIY: Why it falls apart

1. Misallocated engineering talent

For operationally complex businesses, more than 30% of engineering time is spent building and maintaining internal tools—work that doesn’t directly impact customers or revenue. While necessary, it’s ultimately undifferentiated work and engineering time that could be better spent on innovation and driving forward larger company priorities. 

2. Tech debt accumulation

DIY architectures are often hacked together over time, leading to fragile and unsustainable foundations. Inconsistent patterns, patchwork integrations, and tangled dependencies create upgrade headaches and frequent breaking issues. Engineering teams are stuck in “maintenance hell” just to keep internal tools operational.

‍

Technical debt is basically the “tax” a company pays on any development to redress existing technology issues, and it accounts for about 40 percent of IT balance sheets, according to our research. Companies pay an additional 10 to 20 percent to address tech debt on top of the costs of any project.” (Source)

3. Security and compliance risks

When DIY tooling falls short, shadow IT (i.e. tools developed outside of IT’s oversight) creeps in. Ops teams turn to spreadsheets and unauthorized apps, engineers hack together ad-hoc scripts, and critical data becomes scattered or exposed. The result? Security gaps and compliance risks no enterprise can afford.

According to Gartner, “by 2027, 75% of employees will acquire, modify or create technology outside IT’s visibility — up from 41% in 2022.” (Source)

4. The AI multiplier effect

CIO and CTOs are mandated to adopt AI into their strategies, but integrating AI into existing systems can be complex and slow. AI-generated code often lacks audit logs and standardized security controls, creating increased risk of data exposure and operational strain on senior engineers. As demands continue to grow, legacy or DIY tooling becomes increasingly unfit for an AI-driven future.

What CIOs need instead: A secure foundation built for scale and production

To stay competitive, enterprises need internal tools that are secure, scalable, and built to last. That requires a foundation anchored in the below pillars:

1. Centralized governance and security

Scattered access controls and one-off security fixes create risk. Centralized governance brings everything together—unifying permissions, audit trails, integrations, and more—so enterprises can meet regulatory requirements without slowing teams down.

2. Enterprise-ready AI

AI can accelerate development, but without proper guardrails, it introduces risk and inconsistency. AI purpose-built for the enterprise empowers junior developers and semi-technical users to build faster while enforcing coding and design standards, integrating securely with existing systems, and ensuring every app is production-grade from prompt to deployment.

3. Built-in extensibility

Legacy frameworks create friction and slow down innovation. As AI reshapes how software gets built, enterprises need a flexible, future-proof foundation—one that integrates cleanly with existing systems, adapts to emerging technologies, avoids rigid DSLs, and eliminates vendor lock-in.

Introducing Superblocks: Built for enterprise-grade stability and scale

Superblocks gives enterprises a modular, governed alternative to brittle DIY stacks. Instead of reinventing the wheel, teams build faster using standardized building blocks—with fully centralized control and oversight by IT. Developers and semi-technical teams can build how they want, while staying within enterprise guardrails. Senior developers are freed up to focus on high-value, business-critical work.
