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 --skill '*'

Restart or reload your agent after installation. See Agent Skills for 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.
