Nanocoder is an open-source terminal-based AI coding assistant developed by the Nano-Collective community. Designed for software developers who prefer working directly in their shell, Nanocoder orchestrates code generation, repository navigation, and automated file editing workflows directly from the command line. In day-to-day operation, Nanocoder functions as an interactive terminal assistant that parses repository context, executes file modifications, and interacts with LLMs to assist with coding tasks. The project maintains an active TypeScript-based architecture with support for modern Node ecosystems, alongside companion integrations such as a dedicated VS Code plugin powered by an agent control protocol (ACP) client layer. What sets Nanocoder apart is its lightweight, community-funded design and dual-interface approach. While operating primarily as a CLI agent, it offers structured communication protocols to interface with editor environments without locking developers into heavy proprietary frameworks. Nanocoder is fully open-source software distributed under community governance via GitHub and Open Collective. It sees active development with regular version releases distributed via package managers like Homebrew and npm.
Terminal-native interface — Provides an interactive CLI workflow for executing coding prompts, reviewing diffs, and orchestrating edits. - Homebrew and Node distribution — Distributes packaged releases easily through Homebrew formulas and standard Node package registries. - VS Code extension support — Includes a companion VS Code plugin via an internal ACP (Agent Control Protocol) client and process manager. - TypeScript codebase — Built with modern TypeScript and pnpm workspaces for maintainability and extensibility. - Active release cadence — Continuously updated with automated CI pipelines, changeset versioning, and community maintenance.
Use cases
Use Case: Terminal-Driven Refactoring Developers can run Nanocoder directly inside a project directory to perform multi-file code refactors, dependency upgrades, or test additions without leaving their terminal workspace.
Use Case: Hybrid CLI and VS Code Workflows Engineers who switch between shell environments and graphical editors can utilize Nanocoder's core capabilities directly within VS Code via its dedicated ACP integration plugin.
Use Case: Automated CI and Scripting Tasks DevOps engineers and developers can incorporate Nanocoder into automated shell-based scripts or local devcontainers to assist in code generation and linting tasks.
Who it is for
Nanocoder is suited for software engineers, CLI enthusiasts, and open-source contributors looking for a community-driven, scriptable terminal coding assistant. It is less ideal for non-technical users or teams seeking fully managed, enterprise SaaS IDE integrations with out-of-the-box centralized admin consoles.
Install guide
Installation Install Nanocoder using Homebrew (macOS/Linux) or npm/pnpm: bash # Via Homebrew brew install nanocoder # Or via npm globally npm install -g nanocoder
First Run Initialize Nanocoder and configure your preferred AI provider API key in your environment: bash # Set your provider API key export OPENAI_API_KEY="your-api-key-here" # Or export ANTHROPIC_API_KEY="your-api-key-here" # Launch the Nanocoder CLI nanocoder
Example Session Launch Nanocoder inside your project root to ask questions or request code changes: bash cd my-project nanocoder "Refactor source/utils.ts to handle async timeouts cleanly and write corresponding unit tests"
