A decision framework for CTOs and technical founders weighing custom web application development against off-the-shelf SaaS and low-code platforms. Covers five signals that justify a custom build (data-model mismatch, workflow as competitive moat, SaaS ceiling, compliance requirements, deep integration needs), cost tiers ranging from $15k internal tools to $300k+ enterprise platforms, a worked 5-year TCO example for a $120k build (~$366k total), and how AI coding tools like Copilot and Cursor are compressing per-feature costs enough to move the break-even point earlier. Also outlines a four-phase build process and the three most common failure modes: scope creep, maintenance under-budgeting, and building custom what SaaS already solves.
