Cheap Code Does Not Make SaaS Obsolete

The price of turning a clear specification into working code fell. That matters because implementation used to dominate many build-versus-buy decisions. A useful internal tool could lose before anyone examined its value simply because staffing a team to create it cost more than another subscription.

But implementation was never the whole bill. Someone still has to decide what the software should do, control its access, prove that it works, deploy it, watch it, repair it and retire it. Agents can perform much of that labor, but only inside machinery that gives them context, permissions, checks and a recovery route. A fast coding session is not an operating model.

That is why the demo is not the operating model. Agents make a custom route possible more often. They do not make every custom route responsible.

Build when the way your business performs the job is important enough that adopting a vendor's workflow would erase an advantage. The distinction must be concrete: a decision sequence, a data boundary, an integration or an operating rule that changes the outcome. “We prefer our own screen” is not a strategy.

The second condition is ownership. You need the repository, deployment route, credentials, tests and operating records in an environment you control. If the agent can generate the application but only one outside platform can run or repair it, you traded a visible subscription for a harder dependency.

The third condition is a bounded first release. Start with one painful route, not a replacement for an entire vendor suite. Define the result, the people allowed to make consequential decisions, and the evidence that lets ordinary changes move. Our build, buy or blend framework applies this choice capability by capability instead of forcing one answer across the business.

Buy when the job is common, the product meets the real requirements and owning the machinery would not create an advantage. Payroll, commodity messaging and other standardized functions do not become strategic merely because an agent can reproduce part of their interface.

A vendor may also carry obligations you do not want to rebuild: regulatory updates, support coverage, integrations, abuse handling and years of strange edge cases. Compare those capabilities with the complete custom route, not with the cost of generating its first version. The honest alternative to a subscription is software that survives contact with production.

Buying is not surrender. Keep your data exportable, document the boundary and decide what happens if the vendor changes price, access or direction. The factory should be able to route around a replaceable service without pretending every service is worth replacing today.

Compare accepted outcomes over the period in which the software must operate. For SaaS, count the subscription, implementation, integration, process compromises, migration risk and the labor that remains. For a custom route, count specification, agent runs, verification, hosting, monitoring, security, support and recovery. Leave failed attempts in the bill.

Then price change. A standard product spreads updates across its customers, while custom software makes every local choice yours to preserve. The reverse is also true: a vendor's roadmap can force your process to move, while owned software can change exactly when the business needs it. The valuable question is not which side avoids change. It is which side gives you the right to direct it at an acceptable cost.

Do not use cheap code as permission to create low-value inventory. As cheap code makes selection more important, every new system brings proof, operation and future drag. Reject the custom build when those costs outweigh the difference it protects.

Choose one workflow where the current product forces a costly compromise or leaves a valuable job undone. Write the desired behavior in plain language. Mark the data and actions that need permission. Decide what evidence will prove the result, who may approve a consequential change and how the route stops when it cannot prove safety.

Run that slice beside the current process before removing anything. Measure whether completed work is accepted, what intervention it needs and what it costs to keep running. If the custom route wins, expand one boundary at a time. If it does not, keep the evidence and buy the product without pretending the experiment failed to teach you anything.

Gunner Technology's position is simple: agents will move the build-versus-buy boundary, but ownership and operations decide where it lands. Use cheaper implementation to challenge old assumptions. Do not use it to hide a new liability behind an impressive first draft.
