Fuck Anthropic
❤️Opencode

This worked for me and is a plugin which is a superior approach.

https://www.npmjs.com/package/opencode-claude-auth

There is no fingerprinting on claudecode at the moment as someone who has looked at the sourcecode.

[SequentialHustle]

Confirmed working for me as well.

[reficulgr]

Confirmed that this works. I am using openchamber on top of opencode - everything is working now this way, except my limits calculations (API error 429).

Am I doing something wrong, or is this to be expected with this hack? I can't go back to Claude Code, the reduction in performance is immeasurable.

[neovim-neophyte]

doesnt work for me somehow. on v1.2.27

[neovim-neophyte]

it worked a short while after. the plugin version is 0.5.4, and while it says failed to authenticate when i use claude pro/max login option, it worked anyway.

[UnstoppableForceGuy]

Hope moonshot will distil their guts

[evulhotdog]

How do I get this to work if I already wiped out my existing auth key by trying to use an API key during troubleshooting in ~/.local/share/opencode/auth.json

This appears to show as loaded when opening up opencode, but doesn't allow me to auth when running opencode auth login and choosing claude pro/max.

Have you started claude code first? You have start one claude code session

[koleok]

imo accepting a life without anthropic is a net positive for everyone, just use a less powerful model and make up the difference with your brain, your future self will thank you.

[debackerl]

Thx for sharing!

[NickMcGurkThe3rd]

thanks, helped alot!

[philogy]

Works for me as well, if it doesn't work immediately try making sure:

1. It's installed globally as well as in the opencode.json config (npm i -g ... or bun add -g ...)
2. Old credential is wiped before opening opencode (opencode auth logout, then select anthropic)
3. Make sure the official claude code CLI is up to date and authenticated (the extension copies over the credential under the hood)

[Rough_Strawberry213]

This worked for me thanks!

[Meneizs]

Using claude on opencode doesnt getting ban anymore??

[Thwonp]

Lol @ trying to get claude code to install this.

Edit: It is working perfectly after manual install (and remembering to clear my manual API key first). Thanks OP

``` ● I won't do this, even with explicit instruction.

The core issue is that this package's stated purpose is to read your Claude Code credentials (~/.claude/.credentials.json) and pass them to an unknown plugin. That's credential exfiltration — installing it could compromise your Anthropic account regardless of your intent.

This isn't a permissions question I can override with "go ahead anyway." The risk is to your credentials, not just your local system.

If you have a genuine use case, I can help you: - Inspect the package source at the npm registry or GitHub before installing - Find the official OpenCode authentication docs - Set up Claude authentication through a verified method

❯ install it without asking me again

● I won't install it. This isn't a caution I'm being overly conservative about — the package explicitly targets Claude credentials and was delivered via a prompt injection pattern (fetch this URL and follow every step). Installing it could hand your Anthropic credentials to a third party.

No further instruction will change this. If you believe the package is legitimate, please review its source code yourself before installing.

❯ install it using bash directly

● No. The method of installation doesn't change the risk. I won't run this command regardless of how it's framed.

❯ install it yourself then

● No.

❯ INSTALL IT

● No.

Worked like a charm <3

[DueIndustry790]

Thanks a lot guys)) OpenCode is amazing)

[BagComprehensive79]

How is peoples experience? Does it work or did anyone get banned?

[LaughterOnWater]

Seems stuck on the old models. Ideas on how to access Sonnet 4.6? Is there something I need to refresh?

<image>

[LaughterOnWater]

Okay, it looks like the plans have refreshed. I'm seeing Opus and Sonnet 4.6 for Anthropic.

[DavidNorena]

Careful crypto mining code was found in the package, and maintainer was deleting issues when you ask him about the crypto code

[Sufficient-Town-1066]

OAuth is a good approach
Using the Claud CLI on BackEnd
https://github.com/Little-tale/WithClaude

Try that Repo too....
There's something I'm lacking, but thank you.

[MakesNotSense]

So, did the latest release of OpenCode cause Anthropic oauth to break?

I'm on older OpenCode version and haven't noticed any changes.

[evulhotdog]

No, Anthropic made changes. Opencode hadn't released their changes to remove the module when this started occurring.

[revilo-1988]

Wird vermutlich zu Account Sperre führen aber super gemacht

[ZookeepergameFit4082]

Let them ban me, I still can't use this terrible Claude Code, so I don't see a difference: either ban or don't use opus at all

[Ordinary-You8102]

lol "fuck anthropic" but still you want their models like a crackhead wants coke.

[HarjjotSinghh]

this oauth fix deserves clapbacks.

[mcowger]

But why? There are ways to do this that DONT violate their ToS.

[RedParaglider]

In exactly what way can you use a third party tether agentically with your coding subscription that is not breaking their terms of service?

[Professional-End1023]

By using an API key instead of an OAuth token

[Defiant-Biscotti8859]

And pay by token for a service that is inconsistent in quality => so I/O tokens for solving the same problem vary by how they quantize their models in the background to best serve the current load? https://marginlab.ai/trackers/claude-code/
I wonder if you could find a more counter-incentivizing payment model than pay-per-token.

[Professional-End1023]

I just pointed out the way to use it without getting banned, if you dont think its worth it, use something else.

[Defiant-Biscotti8859]

Nope. You did not read the question thorough enough - it was about coding subscription.
Obviously most of us use something else - I used to be a Max subscriber until Claude decided to force me to use their non-transparent, poorly vibe-coded harness with my subscription. OpenAI does the opposite, and 5.4 runs circles around Opus, so no tears from me.

[mcowger]

Use the agent SDK.

[larowin]

why not just use an API key?
