In Elixir/Rails (and newly React) world you can connect Clade Desktop to Tidewave, which gives you pretty close integration with codebase and CLI tools. That makes the experience somewhat similar to running Claude Code in editor's terminal, or now directly connected in Zed.

I think basically all these tools are trying to integrate all the stuff together and find the best way to do that, so that you don't need to be copy-pasting stuff around, jumping between tools, etc.
