It becomes yours and evolves over time.

Nodecode is an agent that rewrites itself. It runs as one process in SBCL, a Common Lisp system, and shells attach to it. The model has one tool: it evaluates Lisp in the running program and keeps what it defines.

Install

Linux and macOS:

curl -fsSL https://nodecode.ai/install.sh | sh

Windows, in PowerShell:

irm https://nodecode.ai/install.ps1 | iex

Then run nodecode. The first launch opens setup. If another coding agent lives on the machine (Claude Code, Codex, Hermes Agent, OpenCode, Cursor CLI, Gemini CLI and 9 more), setup names it and asks before it reads anything; say Import and it brings over the agent’s keys, instructions, memory, skills, MCP servers, bots and jobs, tick the agents one by one when it found several, or Skip and /import brings them over later. Then you pick a provider, a model and the reasoning effort. See Quickstart and First run.

What’s different

Updates while it runs
