Show HN: First Claude Code client for Ollama local models
Just to clarify the background a bit. This project wasn't planned
as a big standalone release at first. On January 16, Ollama added
support for an Anthropic-compatible API, and I was curious how far
this could be pushed in practice. I decided to try plugging local
Ollama models directly into a Claude Code-style workflow and see if
it would actually work end to end. Here is the release note from
Ollama that made this possible: https://ollama.com/blog/claude
Technically, what I do is pretty straightforward: - Detect which
local models are available in Ollama. - When internet access is
unavailable, the client automatically switches to Ollama-backed
local models instead of remote ones. - From the user's
perspective, it is the same Claude Code flow, just backed by local
inference. In practice, the best-performing model so far has been
qwen3-coder:30b. I also tested glm-4.7-flash, which was released
very recently, but it struggles with reliably following tool-
calling instructions, so it is not usable for this workflow yet.
