I think using Aider[1] with Google's models is the closest.
It's my daily driver so far. I switch between the Claude and Gemini models depending on the type of work I'm doing. When I know exactly what I want, I use Claude. When I'm experimenting and discovering, I use Gemini.
I want something running in a VM I can safely let all tools execute without human confirmation and I want to write my own tools and plug them in.
Right now a pro max subscription with Claude code plus my MCP servers seems to be the sweet spot, and a cursory look at the Google ecosystem didn’t identify anything like it. Am I overlooking something?
