A fast agentic coding CLI, in your terminal
A single Rust binary that plans, edits your files, and runs commands — asking before each change. Bring a remote API key or run a model locally.
npm install -g buildwithnexus && bwnEight built-in providers across two wire protocols. Use Anthropic, OpenAI, OpenRouter, Groq, or Hugging Face over the network — or run fully local with Ollama, llama.cpp, or LM Studio, auto-detected at setup.
Three modes: Plan decomposes work into steps you approve, Build runs an agentic loop over file and command tools, and Brainstorm is free-form chat. Spawn subagents to delegate sub-tasks into fresh context.
Mutating tools ask before each change. File access is confined to your working directory, sensitive paths and catastrophic commands always require confirmation, and API keys are never sent over plain HTTP.
