I Replaced My Entire Dev Team With 5 AI Tools — Here’s What Happened After 90 Days

📖 2 min read

The Experiment Nobody Asked For

What happens when you fire your developers and let AI build everything? I tried it for 90 days straight. The results were shocking — and not in the way you’d expect.

The Stack That Replaced a 5K/Month Team

Cursor + Claude handled 80% of the coding. Complex features, debugging, even architecture decisions. Cost: 0/month.

Bolt.new for rapid prototyping. Instead of waiting 2 weeks for a mockup, I had working apps in hours. Cost: bash (free tier).

v0 by Vercel for UI components. Every button, every form, every dashboard — generated in seconds. Cost: bash.

Devin AI for the hard stuff. When Claude got stuck, Devin took over. Cost: 00/month.

GitHub Copilot as backup. Old reliable. Cost: 0/month.

Month 1: Pure Chaos

Everything broke. AI-generated code had subtle bugs that took hours to find. I spent more time reviewing code than I would have writing it. I almost quit.

Month 2: Finding the Rhythm

I learned to prompt better. Broke tasks into smaller chunks. Created templates. Suddenly, I was shipping faster than my old team ever did.

Month 3: The Shocking Results

12 features shipped. 3 complete products launched. Total cost: 30/month vs 5,000/month. That’s a 96% cost reduction.

But here’s what nobody tells you: I worked MORE hours, not fewer. The AI is fast, but you still need a human brain directing it.

The Honest Verdict

AI didn’t replace my dev team. It replaced the NEED for a dev team. Big difference. I still work just as hard — I just spend 4,470 less per month doing it.

Would I go back? Not a chance.

The Tools Ranked

1. Cursor + Claude — Best overall AI coding setup in 2026
2. Bolt.new — Best for MVPs and prototypes
3. Devin AI — Best for complex, multi-file tasks
4. v0 — Best for UI generation
5. GitHub Copilot — Best as a safety net
