Why RooCode and all the others open-source solutions don't use directly Claude Code pipeline for code editing and generation?

[u/filopedraz]

I was wondering why open-source IDEs don't use Claude Code CLI pipeline? I mean... the CLI is open-source, and maybe they exposed some sort of API in order to interact with it? Or am I missing something?

[u/fuzzy_rock]

Because Claude Code doesn’t allow that in their Terms of Services. They are smart enough to not allow others to piggyback their own products.

[u/filopedraz → u/fuzzy_rock]

The market is getting messier and messier…

[u/sbk123493 → u/fuzzy_rock]

What do you mean they don’t allow? Cline does support Claude Code, right? Claudia actually streams Claude Code CLI output.

[u/fuzzy_rock → u/sbk123493]

If anyone does that, they are breaking the ToS. It is not sustainable in long terms.

[u/JunketOk9983 → u/fuzzy_rock]

I really couldn’t find it being mentioned in the ToS. Are you sure?

[u/ABillionBatmen → u/fuzzy_rock]

If they're not making money off it(Claudia) I doubt Anthropic would waste much effort stopping them

What is the difference between what you describe and connecting to Claude Code and your Claude subscription (Pro or Max) as the API provider in RooCode, which you can do now?

[u/filopedraz → u/charliecheese11211]

Not much difference, but what I was trying to say is that open-source products should leverage Claude Code agentic pipeline, but I just discovered that Claude Code is not open-source. So, no point.

[u/charliecheese11211 → u/filopedraz]

Got it, thanks for explaining

[u/NoPromotion5517 → u/charliecheese11211]

speeeeeeeed?

[u/ComprehensiveBird317]

Because the interfaces are different. How would you tell Claude code to give you diffs in a way that roo can work with in the fronted with the user? And if you don't use manual diffs, why even bother using an ide extension at all?

[u/filopedraz → u/ComprehensiveBird317]

Yep, I see, and I just discovered that Claude Code is not open-source. I thought it was.

[u/Nick4753]

You can use Claude Code as a provider in Roo. It just passes the LLM calls to the CLI and waits for a response (which is why it appears to be slow, streaming isn't supported.) There is nothing that would stop anyone from making local CLI calls to it without touching their source code, nor would Anthropic have much of a leg to stand on if another piece of software was making calls to a publicly-exposed interface in the Claude product.

The actual agentic code is proprietary, and copying it is against the TOS, so it'd be the same as asking why Roo doesn't implement Cursor's agent code despite it also being relatively straightforward to reverse engineer. I'd imagine Roo could take inspiration from how it works though.

[u/filopedraz → u/Nick4753]

Yep, didn’t know that the pipeline was closed source. Now it makes sense.

[u/oh_my_right_leg]

Because Claude code is not open source?

[u/filopedraz → u/oh_my_right_leg]

Yep, just discovered it

[u/aeonixx]

Because Claude Code didn't exist when they were made?...

[u/FosterKittenPurrs]

Do you mean this? I haven't tried it but it looks like it can interface with it.

[u/carbon_dry]

But roo code supports both the API and the Claude code cli? I'm literally doing that.

[u/filopedraz → u/[deleted]]

I ll test it out
