Claude Code has the better UX, while Codex chases mass-market design and suffers for it.

Reports Codex filled about 12 GB with old versions, and rates it worse than Claude Code on every metric.

HN comment · Oct 12, 2026Read on HN ↗

Codex quality and reliability have declined, and its coding falls short of Claude Code with Opus.

HN comment · Oct 7, 2026Read on HN ↗

Codex cloud agents force you onto your own machine, while Claude Code works better as a cloud dev environment.

Picked OpenAI Codex 181 developers

Opus drains a weekly quota in a day or two while Codex keeps running, and finds more flaws in Claude's commits.

HN comment · Oct 29, 2026Read on HN ↗

Switched from Claude to Codex because the Claude Code harness feels unstable and frustrating.

> They don’t really. Most normies which are the vast majority of people just use ChatGPT. All tech folk just use Claude. It was the case a year ago, but it's less clear cut nowadays, I've seen non-tech people using claude on their phone in the train, and many tech people seem to have switched from Claude Code + Opus to Codex + Sol over the past few month.

HN comment · Oct 13, 2026Read on HN ↗

Picks Codex for more generous usage limits and resets, plus unmetered ChatGPT access on the 20x plan.
