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.
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.
BotStopper checks requests between your load balancer and app. It blocks some bot requests and allows others to continue to your app.
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.
Match challenge pages to your website with your own images, fonts, CSS, and messages. Customization gives visitors a consistent experience when they encounter a challenge.
Use metrics and logs 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 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:
BotStopper costs US$50 per month, paid through GitHub Sponsors. Your deployment also needs hosting and ongoing operation.
