The Problem That Started It All​

I was living the dream: Claude Code was building my entire SaaS application from scratch. Feature by feature, API by API, frontend by frontend - Claude was coding faster than I could even think of requirements. But then reality hit like a brick wall.

Claude is brilliant at coding but completely blind when it comes to testing its own work.

Here's what happened: I watched Claude iterate endlessly on "fixes" that didn't work, with absolutely no clue what was actually happening in the browser when real users connected. The app would break, Claude would guess at solutions, make changes, and... nothing. No visibility. No feedback. Just endless iterations based on assumptions.

This is the critical missing piece that prevents Claude from being a truly autonomous development team. It can build your entire startup idea into a full SaaS app without any human help, but it fails catastrophically at testing its own work.

When I tried to solve this with browser automation on my ARM64 Raspberry Pi 5, I hit the infamous error:

Failed to initialize browser: Executable doesn't exist at 
/home/pi/.cache/ms-playwright/chromium_headless_shell-1179/chrome-linux/headless_shell

The standard MCP browser servers (Playwright, Puppeteer) simply don't work on ARM64. This wasn't just a technical inconvenience - it was the missing link that prevented completing the autonomous development loop from idea to production SaaS.
