BotD documentation

## BotD

BotD is an open source library that we created to make it easy for every developer to detect basic bots in their web apps.

It is available under a permissive MIT license and will always be free for developers and commercial use.

For more demanding applications we created a professional API-based bot detection software that is called [Fingerprint Pro Bot Detection](https://fingerprint.com/products/bot-detection/).

[⚑ View Our Demo](https://fingerprintjs.github.io/BotD).

## Quick start

### CDN

```html

// Initialize an agent at application startup, once per page/app.
const botdPromise = import('https://openfpcdn.io/botd/v1').then((Botd) => Botd.load())
// Get detection results when you need them.
botdPromise
.then((botd) => botd.detect())
.then((result) => console.log(result))
.catch((error) => console.error(error))

```

[Run this code](https://stackblitz.com/edit/botd-cdn-tkdie9?devtoolsheight=100&file=index.html)

### NPM

```bash
npm i @fingerprintjs/botd
# or
yarn add @fingerprintjs/botd
```

```js
import { load } from '@fingerprintjs/botd'

// Initialize an agent at application startup, once per page/app.
const botdPromise = load()
// Get detection results when you need them.
botdPromise
.then((botd) => botd.detect())
.then((result) => console.log(result))
.catch((error) => console.error(error))
```

## πŸ€– Upgrade to Fingerprint Pro Bot Detection to detect sophisticated bots with confidence.

[Fingerprint Pro Bot Detection](https://fingerprint.com/products/bot-detection/) is a professional bot detection service that processes all information server-side and transmits it securely to your servers using server-to-server APIs.

Fingerprint Pro Bot Detection provides both browser and server-side APIs that make the process of bot detection fast and secure. When using the Pro Bot Detection, use the browser JavaScript SDK to obtain the requestID value and then verify this value using our server API.

The Pro product combines vast amounts of auxiliary data that bots leak (cursor movements, network overrides, browser changes and more) to be able to reliably deduplicate real users from automated software, resulting in the detection of popular automation tools, their derivatives and plugins.

A big advantage of the Pro detection is that it's able to distinguish good bots from bad ones that allow you to block malicious traffic without blocking search engine crawlers, monitoring workers, etc.

1. Pro uses the open source BotD library as well as proprietary technology for increased accuracy and result stability.

2. Fingerprint Pro is GDPR and CCPA compliant as the data processor. You still need to be compliant as the data controller and use the bot detection for fraud prevention under legitimate interest or ask for user consent.

Pro result example:

```js
{
"bot": {
"result": "bad"
"type": "selenium"
}
}
```
