The Hidden Cost of Building AI Software Instead of SaaS

The "SaaSpocalypse" narrative—that generative AI will make custom software cheap enough to kill subscription services—ignores the messy reality of maintaining, securing, and updating homegrown tools at scale. Companies trading predictable SaaS fees for internally built alternatives will discover that AI-generated code requires the same DevOps infrastructure, security audits, and technical debt management as traditional software, just without vendor support or roadmap certainty. The arbitrage isn't between SaaS and DIY, but between companies disciplined enough to calculate total cost of ownership and those chasing the fantasy of free software.
