I use qwen2.5-coder via neovim plugin, Qwen3 directly via llama.cpp, aider with qwen3 for big things that need context, and just copy and paste to/from claude using a special "heredoc" shellscript I wrote which lets me just put most of the project directly into the chat and copy changes back out in one operation.

They don't do anything I couldn't but they keep my momentum from dying when I get annoyed/distracted/frustrated which is a game changer.
