[Arcjet][arcjet] is the runtime security platform that ships with your AI code. Stop bots and automated attacks from burning your AI budget, leaking data, or misusing tools with Arcjet's AI security building blocks.
This is the monorepo containing various [Arcjet][arcjet] open source packages
for JS.
## Which package do I need?
Arcjet protects two types of entry points. Pick the right path for your use
case:
| Entry point | When to use | Package |
| ---------------------- | -------------------------------------------------------------------------------------------------------------- | --------------------------------------------------- |
| **Request protection** | HTTP route handlers, API endpoints, middleware — anything with an incoming `Request` object. | `@arcjet/next`, `@arcjet/node`, `@arcjet/bun`, etc. |
| **Guard protection** | AI agent tool calls, MCP server handlers, queue workers, background jobs — anything _without_ an HTTP request. | [`@arcjet/guard`](./arcjet-guard/README.md) |
Not sure? If you have an HTTP request, use a [framework SDK](#sdks). If you
don't, use [`@arcjet/guard`](./arcjet-guard/README.md). You can use both in the
same project.
## Getting started
The fastest way to get started is with an AI coding agent. Log in, install
a skill, and let your agent handle the rest.
### Step 1: Log in with the CLI
```sh
npx @arcjet/cli auth login
```
You can also sign up and manage keys at
[`app.arcjet.com`](https://app.arcjet.com?utm_campaign=arcjet-js), or connect
the [Arcjet MCP server](https://docs.arcjet.com/mcp-server) to your AI
assistant.
### Step 2: Install a skill
Skills give your agent the documentation to detect your framework, install
the SDK, and wire up request or guard protection rules.
```sh
npx skills add arcjet/skills
```
> You can also use the [Arcjet plugin for Claude Code and
> Cursor](https://docs.arcjet.com/arcjet-plugin), which bundles skills, MCP,
> and coding rules.
### Step 3: Install the package
**For request protection** — pick the SDK for your framework:
| Framework | Package | Install |
| ------------ | ------------------------------- | ---------------------------- |
| Next.js | `@arcjet/next` | `npm i @arcjet/next` |
| Node.js | `@arcjet/node` | `npm i @arcjet/node` |
| Bun | `@arcjet/bun` | `bun add @arcjet/bun` |
| Deno | `@arcjet/deno` | `deno add npm:@arcjet/deno` |
| Express | `@arcjet/node` | `npm i @arcjet/node` |
| Fastify | `@arcjet/fastify` | `npm i @arcjet/fastify` |
| Hono | `@arcjet/node` or `@arcjet/bun` | `npm i @arcjet/node` |
| NestJS | `@arcjet/nest` | `npm i @arcjet/nest` |
| Nuxt | `@arcjet/nuxt` | `npm i @arcjet/nuxt` |
| Remix | `@arcjet/remix` | `npm i @arcjet/remix` |
| React Router | `@arcjet/react-router` | `npm i @arcjet/react-router` |
| SvelteKit | `@aExcerpt of 37,514 characters

Would you bet a product on this? Bounded 0–100 and slow moving.
