Nanocoder

The open alternative.

Nanocoder is a community-built, multi-provider coding agent that runs entirely in your terminal. It connects to Ollama for local execution, or OpenRouter, Anthropic, OpenAI, and Google for cloud inference.

Built by the Nano Collective rather than a company, it enforces a strict privacy-first model: your codebase never leaves your machine unless you explicitly send it to an API of your choice. No tracking, no forced telemetry, no vendor lock-in.

Premium capabilities.
Zero paid tiers.

Local First

Runs entirely on your machine. Connect to local Ollama models for completely offline, zero-cost agentic coding.

Multi Provider

Seamlessly switch between OpenRouter, Anthropic, OpenAI, and Google. You choose the intelligence engine.

Skills System

Extend behavior through custom skills. Teach Nanocoder your codebase's exact conventions and workflows.

Custom Tools

Create and integrate your own Bash or Python tools directly into the agent's toolbelt.

Multiple Modes

Boot directly into Normal, Plan, Auto-Accept, or YOLO mode depending on your trust level for the task.

Open Source

Built in public by contributors. The codebase is yours to read, audit, and improve.

Privacy First

No forced telemetry. No silent data collection. Complete control over what leaves your network.

Terminal Native

Designed explicitly for terminal workflows. Fits seamlessly into your existing developer environment.

Realistic workflows.

Nanocoder handles architecture, refactoring, and feature building natively in your terminal.

Refactor

$ nanocoder run "refactor database module"

⚒ read_file

Path: src/db/users.ts

⚒ string_replace

12 - await sql("SELECT * FROM users")

12 + await db.user.findMany()

⚒ execute_bash

Command: npm run typecheck

● exit 0

Refactored 12 queries across 2 files

Audit

$ nanocoder --mode plan run "audit auth module"

⚒ read_file

Path: src/auth/jwt.ts

⚙ Thought
Reviewing token expiry and login throttling.

1. Verify JWT expiration logic
2. Check password hashing rounds
3. Audit rate limiting on /login

⚠ No rate limiter on POST /login

Why developers choose Nanocoder

100% Open Source

Read the code. Audit the code. Improve the code. It belongs to the community, not a corporation.

Local Architecture

Designed from the ground up to run inference locally, ensuring maximum privacy and zero latency costs.

Bring Your Own Model

Plug in any compatible local model, or route through the APIs you already pay for.

Zero Vendor Lock-In

If you don't like Nanocoder, you can uninstall it. Your project history and Git tree remain completely untouched.

Community Driven

Features are built based on what developers actually need, not what looks good in a marketing pitch.

Highly Extensible

A robust plugin ecosystem means you can tailor the agent perfectly to your unique tech stack.
