CROSS-CATEGORY Solo Dev 'SaaS Apocalypse' Playbook: AI Coding Rebuilds 7 SaaS Categories In-House — $60K Annual Savings Documented

DEV Community·high signal

DEV Community analysis documents solo developers using Cursor and Claude Code to rebuild document automation, task coordination, CRM basics, time tracking, BI, chatbots, and marketing automation in-house. One documented case study saves $60K annually in SaaS subscriptions. The micro-SaaS market is projected to grow from $15.7B to $59.6B by 2030 at 30% CAGR, partly fueled by builders productizing these in-house replacements into commercial tools — creating a second demand-destruction vector on top of agent seat compression.
