Installation

Install Fentaris and prepare your local environment.

Requirements

• Node.js 20+ for generated Fentaris projects and SDK-only apps
• Node.js 24 for developing this monorepo
• pnpm or npm

Fentaris runtime packages support Node.js 20 and newer. The Fentaris repository itself uses pnpm@11.18.0 and CI runs on Node.js 24, so use Node.js 24 when installing or testing the monorepo.

Install the CLI

Use the CLI for the fastest project setup:

pnpm

pnpm add -g @fentaris/cli

Install @fentaris/core directly

Use the core package directly when embedding Fentaris in an existing TypeScript project:

pnpm

pnpm add @fentaris/core

Install agent skills

Use the optional agent skills when you want Codex, Claude Code, or another supported agent to guide Fentaris setup, ask workflow questions, configure a proxy project, or modify an existing Fentaris app:

npx skills add Fentaris/fentaris-skills -g -a codex --skill '*'

The global install keeps the project directory empty for fentaris init. Restart or reload your agent after installation. See Agent Skills for other agents, install options, and example prompts.

Verify installation

Create a quick file and import the high-level Fentaris helpers:

import { fentaris, mcp, stdio } from "@fentaris/core";

console.log(typeof fentaris, typeof mcp, typeof stdio);

If your build succeeds, Fentaris is installed.
