Nanocode Reviews — Discover what people think of this product.

Nanocode is a minimalist, open-source Claude Code alternative packaged in a single Python file with zero external dependencies. Designed for developers who want a lightweight, transparent coding companion, it delivers a full agentic loop for working with files and the shell directly from your terminal. With roughly 250 lines of well-structured code, you can easily read, understand, and customize how it operates.

Built using Claude Code and then used to build itself, Nanocode focuses on practical capabilities instead of heavy frameworks. It supports conversation history, colored terminal output, and a focused set of tools for real-world coding workflows. No complex setup, no dependency hell—just export your ANTHROPIC_API_KEY and start coding.

Key capabilities include:

• File inspection: read with line numbers, offsets, and limits
• Editing operations: write and edit for precise, unique string replacements
• Project navigation: glob and grep for pattern-based file discovery and regex search
• Shell integration: bash execution within the agent loop

Nanocode is ideal for developers who value clarity, hackability, and minimalism. Whether you’re exploring agentic coding, experimenting with AI-assisted development, or building your own custom dev assistant, this repository gives you a compact, auditable starting point without sacrificing powerful functionality.
