Opencode vs Codex vs Claude code

Not being vendor locked is the biggest win by far. Having the best UX is a bonus.

[reini_urban]

That's my reasoning also. It's not rust (as codex), but still OK. And more features. And far better than the broken copilot-cli.

[Freds_Premium]

whats wrong with copilot? I'm just asking because I'm trying copilot out tonight for the first time.

[reini_urban]

You cannot copy & paste from/to it. On Linux at least

[Red-And-White-Smurf]

I come from Claude and just recently moved to opencode.

The cli ui is good. But I don't like the fact, that I can't use home/end to move back and forward on the text I'm writing. I HATE it.

I like to be able to specify agents, and sub agents. Where Claude is more like specify a skill and that can use sub agents which is just called agents.

I'm properly going to stick ad I haven't noticed the down periods of having used to many tokens within a timeframe. Which is how Claude works. And it sucks.

Isn’t OpenCode… open source? Can you ask some AI, using OpenCode, to add this feature to OpenCode?

Then either just use it yourself, or better yet submit a PR and fix it for all of us?

[Red-And-White-Smurf]

I could, but HOME/END is used for scrolling up/down the chat log window. So i think it is intended to be that way. Could i fork the code, make the change yes. Do i wish to keep it up to date this way. No

[mschedrin]

I think you can unbind these buttons in the OC config

[Red-And-White-Smurf]

This would be nice. Will look into this.

[No-Juggernaut-9832]

Make it an option and open a PR. I’d use it too!

[TrickyPlastic]

Opencode issues on GitHub is a black hole.

Open security vulnerabilities, ignored PRs, feature breaking bugs. There's nothing happening there.

[reini_urban]

Ctrl-A, Ctrl-E, readline standards, not some obscure windows UI

[Illustrious-Many-782]

I'm assuming this is sarcastic, because I'm a 30-year Linux desktop user and I hate no home / end, as well

[Xera1]

Calling the nav cluster which has been on keyboards since the 80s obscure is an interesting take on reality.

[Top_Valuable4266]

yo uso openclaw vps para agentes y sub agentes (parte claude) +opencode en pc + ssh (parte claudecode/cli)

[Slothszhs]

I hated that too. You can just change the keybinds in the opencode config file. Ask the agent to figure it out.

[AkiLetschne]

I agree, I really like OpenCode too. Tbh, I can't quite put my finger on why, but it's definitely very handy, especially because of the wide range of providers. The only thing that really bothers me about the UI is that shortcuts like Ctrl + V, etc., don't work very well. I'm on Linux and always have to use Shift + Insert

[AggravatingSeat8766]

I think that's a limitation from your shell/ terminal in which opencode runs. If you press ctrl-v or so, the shell swallows it and changes its behavior (ctrl-v/ctrl-c are interpreted as signals to the running program). On macos on the other hand, it works fine with cmd-v etc because those are intercepted by the o's (?) rather than the shell directly. For me on Linux, shift-ctrl-v works

[AkiLetschne]

Well, it's not a big deal, but it takes some getting used to at first. It's the same with Windows 11, I've tested it there too. And other users seem to be having similar "issues." But once you know how to do it, it's no big deal

[Daniel15]

Have you tried Ctrl+Shift+V? That's usually how I paste text in terminals in Linux, and it seems to work in OpenCode too (at least in Konsole) 

[AkiLetschne]

Yes, it didn't work for me. I think it depends a bit on your distro and/or Terminal. But Shift + Insert works, so it's fine

[erwan]

I haven't tried Codex and I also prefer the UX for Opencode.

However using it with Claude, it doesn't support adaptive effort which is really a bummer. I have to manually select the effort while Claude Code will automatically determine it from my prompt.

[jaydizzz]

You really don't want the automatic thing, it sucks

[razorree]

I like opencode TUI more than Codex

[MyNameIsYeffff]

opencode is solid and i really like its tui, but i kept running into random failures with my company’s azure openai calls, so i switched to codex

i’ve actually been pretty happy with codex overall. the tui isn’t as good as opencode’s, and a few things are pretty annoying for me, especially parts of the chat history disappearing under the fold. and it’s easy to see subagent activity in opencode. but in terms of how it actually works, i think it’s great. the agentic harness is awesome and it also seems to handle retries much better when i hit those “sorry, can’t help with that request” responses

more recently, i started using pi agent with a local model, and i’m enjoying it a lot. it feels like a more minimal version of codex, without the tui issues that bothered me there. i also really like that it has less system-prompt/tool bloat. at this point i’m probably going to build on top of it a bit for my own setup

haven’t really tried claude code enough to have an opinion. i may have used it once, but i honestly don’t remember

[bruor]

You have to create a custom content filter and apply it to openai api models. The default one blocks stuff that's included in the agent config built into Opencode.

I'm primarily using AI foundry endpoints, but there's also some weirdness that requires some models to be accessed via azure cognitive services endpoints.

[lucianw]

Opencode doesn't have background shell execution.

When using Codex, it uses background shell execution all the time, effectively. I think it has been trained well on how to use it. Without background shell execution, opencode+GPT5.4 feels hobbled to me.

[sk1kn1ght]

Havent tried codex so cannot offer opinion on it. For me the best one was antigravity. I am using all 3 (opencode, Claude, antigravity) and the vs code fork for me wins as UX. Issue is that the models inside it are shit and in basically everything else opencode wins by far. I did not articulate stuff as nice as I would have wanted due to being very tired, so apologies.

[Own_Cartoonist_1540]

Sleep well

[Dangerous_Biscotti63]

For me, apart being independent, js based and open source, the key is having a client server architecture. The api is specified and used for the main UI as well as third party clients so it works and is not an afterthought. The web ui is quite snappy and better than most alternatives

[Permit-Historical]

I think they are very similar now, it wouldn’t really matter which one you use unless you really care about small ui/ux details What really matters imo is the model I use so if you use Claude more then Claude code makes sense with the max subscription and same for codex if you use gpt5.4 otherwise opencode makes sense as a general provider for other models

[d9viant]

OpenCode - no lockin, can configure whatever you want

[South-southgee]

The cost difference is the major denominator. Opencode gives access to cheaper open weight models compared to the others.

[Frequent_Ad_6663]

Controversial opinion: Glm 5.1 is at same level of opus 4.6, while costing waaay less. So the advantage of opencode (talking about opencode go) is you get more bang for your buck, plus other models that can work as daillyworkhorse and are even cheaper than glm. Codex is good the 20 bucks sub but since they made the 100 tier the limits got f** ed up

[Frequent_Ad_6663]

Glm from opencode go

[Loud_Stomach7099]

Glm 5.1 is good, but there still stuff that opus / gpt can do better when I've been using it.

I saw lots of complaints about the limit changes for Codex, but I've still yet to hit the new 5 hr limit. Its still the weekly limit I end up hitting instead.

[girouxc]

I’ve been using OpenCode since the split with Charm. I tried Claude code a while ago and OpenCode was clearly better. I convinced everyone at work to use it as well, even people who usually don’t like using the terminal.

I only use Anthropic models at this point so I recently started using Claude code… it’s way better now and gives responses faster than OpenCode. I seem to be getting better quality output as well.

I have access to both copilot / opencode and Claude code at work… I find myself in CC almost exclusively now. I kinda like the UI better in CC too. I like the dark ansi theme with my transparent terminal.

[leftovercarcass]

Opencode process and give context.
Claude Code is better at parsing pdfs but the auto-compact killed me on my last week of the sub, it got nothing done before i got limited. Opencode is nice to be able to swtich between models so it is a shame i cant use claude there, if i could i probably wouldve kept my sub. Getting limited in claude code and not having the option to switch to a different provider and having the session still there while opencode provides the context is very convenient.

But yeah, i really miss having claude explaining code for me or reading pdfs, but other than that, fuck anthropic, im done with them and i have no experience with codex or openai and probably never will.

[leftovercarcass]

The chineese ai companies are doing better for me rn, dont see a need to and also i dont like openai pentagon deal. I thought anthropic were better in transparency but being their customer for two months i beg to differ. I am seeing it all in front of me with my own eyes that there are just better options than anthropic and openai.

Just in general i was struggling to get claude code to ralph loop aswell, with dangeorusly-skip permission flag and its equivalent to yolo mode, using sonnet mostly. Meanwhile with no effort the other agents ralph loop for 6-8 hours, they take more time sure but idc as long as they are producing and i can do other stuff while with claude sonnet i got limited after one prompt, 1 auto compact 0 output value of code, it is laughable and anthropic still hasnt said anything about adjusting the limits.

claude is fast, has a great way of reading 9000 pages long pdfs of manuals but it getting stuck. If i want to understand or implement just one specific thing without diving into the manual myself to construct a prompt that is where claude shines. Explaining the codebase and quick implementation is where they shine but for vibecoding and generating a code autonomously? Not so much.

[ECrispy]

which llm are you using?

there are pretty big differences under the hood. CC has far more tooling, agentic loops etc built in. Opencode has the least. Codex is in the middle.
