I saw Codex was screenshotting, then clicking around. I just stopped it and never used that again. Using CLI tools is much faster and token-efficient. I developed ten apps in the last two months. One reached 10,000+ monthly active users. I ask Codex to generate SVG line by line and backtrack edit, ask it to use Inkscape to generate icons, etc... I developed all this on $20 codex sub.
It breaks like 80% of the time for me, and it's incredibly slow. Having it use Playwright (bonus: can test in FF/Saf too) was a big improvement.
