> Isn't Claude-code a proprietary version of https://aider.chat/ in the first place? It might be; but aider is Apache 2 licensed and I don't think Anthropic would be able to change the license. But either way, these tools are simple enough that it's not hard to replicate what they do. So simple that it's kind of pointless for Anthropic to get proprietary and protective about the whole thing. The moat they have is with the model quality. I saw a very similar tool demoed at the local Kotlin meetup in Berlin just one day after Anthropic announced claude code that also uses the Claude API. https://github.com/xemantic/claudine Kotlin might not be everybody's cup of tea but actually seems to be an effective tool for the job. The level of simplicity of the code base is what I found the most shocking. There's almost nothing to it. It's tiny bits
Read the rest
of code needed to read/write files and execute commands and a very simple loop where it interacts with claude via a simple REST API. You can read through the code base (a couple of hundred lines of Kotlin) in a few minutes and get a feel for what it does. We had some fun trying to get the tool to improve itself during the meetup. It worked pretty well. Probably, the most complex thing of the whole code base is the system prompt used to orchestrate the whole thing. That looks like some thought went into it and there are probably a few gotchas that are yet to be addressed. But even that is doable. A determined person could probably replicate what this does in a day or so from scratch. Probably a lot faster if you use one of these tools to build the next one. This isn't rocket science. I'm guessing we'll be seeing a lot of tools like this in the next few months. It will be interesting to see what refinements people come up with. I think most of the innovation is going to be in giving these agents better/smarter tools to work with. For example, there's a lot of stuff encapsulated in IDEs that it probably a lot easier to use than trying to do the same thing with random cli commands.
