Try Kilocode with deepseek v4 (via API directly to deepseek, much cheaper than via kilo).

I have had very good results and compared to others it just costs pennies.

I use something similar to this https://github.com/ScotterMonk/AgentAutoFlow setup and switch between deepseek v4 to flash depending on task.

I do use DeepSeek, it's exceptionally cheap! Inference is slow though, and it's not particularly intelligent but the experience is better than local inference.
