I use self hosted Open WebUI + open terminal instances on my development machines + DS Flash 4.1 + my own custom OWUI plugins for various things like per chat access grants for the open-terminal instances, per chat git credentials for traceability, and another plugin to enable inter-chat communication. Couldn't ask for more at this point. Been burning billions of tokens per week for maybe ~20 bucks thanks to how cheap Deepseek is with token caching for a wide range of development tasks.
