Codex is accurate but slow (too slow), and Claude is fast but makes a ton of mistakes. So I decided to use Claude and codex together. Let Codex do the bugfix and identify what to do, and Claude do the coding based on Codex's instruction. This way I achieved more efficiency. Answer from Lunarcat2025 on reddit.com

r/Anthropic on Reddit: Codex vs Claude Code – $20 plan, month ending… which one are you devs sticking with?
September 27, 2025 -

Month’s ending and I need to pick which $20 plan is worth it for dev work – Codex or Claude Code?

Here’s my honest take so far:

Claude Code → I used to love it. Great with Python + terminal, but after the August downgrade it’s never been the same. Tried the “downgrade” version trick Reddit folks suggested it helped, but still not at that old level.

Codex → very Good at code understanding, bug fixing, and handling long Python codebases. I like the small/medium/large options… but the weekly limits suck. Also weaker in terminal tasks, slower on Windows, and keeps asking approvals every time.

So both have pros/cons. If you’re coding daily, which one feels like the real win for $20 right now? Would love to hear honest dev-side experiences before I renew.

Codex vs Claude Code: which is the better AI coding agent?
September 28, 2025 - Codex also lets me pick low, medium, high, or even minimal reasoning for super fast runs. I like these options more than having just two model choices in Claude Code. Cursor on the other hand has a lot of options, which is cool in theory, but can be a bit overwhelming in practice. I like that the same company making the tool is training the models as they should know how to use it best and be able to give me the best price as there is no middleman that also needs a margin.
People also ask

Is Codex still better than Claude Code in 2026?
Codex still wins on GitHub integration and pricing. But Claude Code has closed the gap significantly — better UX, a VS Code extension, a web IDE, and Cowork mode. Which is better depends on your workflow. If you live in the terminal and care about GitHub automation, Codex. If you want more configuration options and hooks, Claude Code.

Does Claude Code still not support AGENTS.md?
Correct as of this writing. Claude Code uses CLAUDE.md. If you want one instructions file that works across tools, use AGENTS.md for Codex, Cursor, and Builder.io, and keep a synced CLAUDE.md for Claude Code.

r/ClaudeAI on Reddit: Claude Code $20 vs Codex $20 – Which Is Better Value?
February 13, 2026 -

Hey everyone,

I’m trying to decide between Claude Code ($20 plan) and OpenAI Codex via ChatGPT Plus ($20 plan).

I mainly use AI for regular dev work — bug fixes, refactoring, small features sometimes big, and some vibe coding. I care about:

  • 💻 Code quality & accuracy

  • ⚡ Performance/speed

  • 📊 Usage limits for the price

  • 💰 Overall value for $20

If you’ve used both, which one would you pick and why? Any issues with limits, reliability, or real-world workflow integration?
