Indie dev's AI coding bill hit ~$4,000 building MailCheap, making it his first unprofitable product

Indie developer marclou shares that building his email product MailCheap with Opus via Cursor cost him about $4,000, ironically making it his first unprofitable product — the AI coding spend outran the revenue.
He jokes he's now running "brain dead": 10 agents at 2x speed on 5.5 Max, burning more tokens. A vivid case of vibe coding economics: AI makes shipping insanely fast, but heavy multi-agent usage can easily push costs above what a small product earns.
