Please… Enough with the Sloppy, One-Shot SaaS Replacements — Mahmoud Abdelwahab, Railway
Tech stack quality still matters when building polished internal tools with AI agents
“there is one missing element that is rarely mentioned: the vast gulf between working software created on the fly and software that I would actually use”
Railway's developer advocate built a comprehensive internal marketing platform (CMS, email, social, CRM, task tracking) entirely with AI agents, replacing multiple SaaS tools. He argues the 'SaaS is dead' narrative ignores the gap between working and polished software, and that a well-structured codebase with solid abstractions produces far more consistent agent output. The talk offers transferable principles for teams pursuing agent-built internal tooling.
