I hesitate trying Claude Code, there is a bit of fatigue installing new tools :-)
By the way: ChatGPT 5.1 Codex Max pro, which was rubbish when used directly inside Cursor, is actually very good once I access it via the OpenAI Codex extension installed within Cursor!
Mysteries of toolchains...
Anyway, that proved so useful when I maxed out my Claude credits.
Do you mean codex or Claude code standalone without cursor? Codex is OpenAI’s coding tool competing with Claude.
Based on my limited experimentation Claude code is better. I haven’t used any of these coding agents with an ide only from the cli.
