# BotStopper

BotStopper helps keep your website available to people by controlling automated
access before requests reach your application. It gives you tools to protect
public content from AI scrapers and other unwanted automation.

Run BotStopper in infrastructure you choose, in front of your existing website.
Your team controls access policies, the visitor experience, and the protection
you apply to different requests.

## Protect your content and your resources

Repeated scraper requests consume bandwidth and application capacity.
BotStopper evaluates incoming traffic and applies your access rules before it
reaches the protected application. You can admit approved clients, challenge
suspicious traffic, and deny unwanted automation.

Browser challenges add work to repeated access. BotStopper also offers headless
browser detection to identify signs of automation. These tools help you make
scraping more expensive while preserving access for the visitors you want.

## Control who gets through

Search crawlers, feed readers, monitoring tools, and API clients have different
needs. BotStopper gives you policies to treat each group appropriately.
You decide which automation serves your site and which automation consumes
resources without your permission.

Policies can vary across your site. Protect public content, make exceptions
for approved services, and adjust your rules as traffic changes.

## Make the protection yours

Match challenge pages to your website with your own images, fonts, CSS, and
messages. [Customization](/docs/customization.md) gives visitors a consistent
experience when they encounter a challenge.

Use [metrics](/docs/policies/metrics.md) and [logs](/docs/policies/logging.md) to
understand request decisions and operate the service. BotStopper supports
binary packages, containers, and Kubernetes, so you can fit it into your
existing deployment process.

## Anubis and BotStopper

[Anubis](https://anubis.techaro.lol) is the free, open source version of
BotStopper. Techaro builds both products, and both share the same policy and
challenge engine.

BotStopper adds features and support for teams that want more from their
scraper protection:

- [Headless browser detection](/docs/extensions/headless.md) examines automation signals and makes them available to your access policies.
- [soteria](/docs/challenges/soteria.md) adds another challenge option for scraper protection.
- Dedicated support from the team that builds Anubis and BotStopper.

BotStopper costs [US$50 per month](/pricing), paid through GitHub Sponsors.
Your deployment also needs hosting and ongoing operation.
