What is it?

Nanocoder is a coding agent that runs in your terminal. You choose the model: local models through Ollama, or hosted providers exposing an OpenAI-compatible API such as OpenRouter, Requesty, Anthropic, and Google. Because you pick the provider, you decide where your code and prompts are sent.

It is built by the Nano Collective, a community group rather than a company, and the project states it has no paid tiers and no closed-source features. It offers non-interactive runs with a prompt, development modes including auto-accept, plan, and architect, and commands to review a branch or PR and to open a PR in an isolated git worktree for a session.

The interface has a fullscreen mode with in-app scrolling and an inline mode that keeps the transcript in the terminal's native scrollback.

  • 04Reviews a branch or PR diff for bugs, security issues, and style violations.
  • 05Opens a PR in an isolated git worktree for a coding session.
  • 06Fullscreen and inline screen modes.

Use cases
