Migration from Claude Code to a private local harness. Questions.

A user accustomed to Claude Code is seeking advice on migrating to a local, open-source, and free harness due to concerns about potential cost increases. They are familiar with running local models like Qwen3.8_Q5 in LM Studio but lack experience with other harnesses. The user, who has 24GB VRAM (RTX 3090) and 64GB DDR4, is looking for a solution that offers the least resistance for someone new to coding, prioritizing ease of use over advanced control for now.

Unlike many discussions focusing on model capabilities, this post highlights a user's practical concerns about cost and migration from a commercial AI coding tool to a local, open-source alternative.
