Protect Your Website from
AI Training Bots
Make your website invisible to AI scrapers. The universal "No-Trespassing" sign for bots with a single line of code.
Why AntiScrape?
The rapid proliferation of Large Language Models (LLMs) has led to an unprecedented scale of distinct web scraping activities, often disregarding the `robots.txt` protocol. AntiScrape proposes a client-side sovereignty standard, empowering web administrators to reclaim control over their digital footprint. By identifying and neutralizing unauthorized scraping agents at the browser level, we preserve the economic and intellectual integrity of human-generated content.
Experimental Initiative: This project is an open-source experiment. We actively invite the community to help classify and expand the registry.
Platform Agnostic
AntiScrape is a static resource compatible with 100% of web infrastructure. Since the logic runs in the user's browser, it works on:
- GitHub Pages & Static Sites
- WordPress, Ghost, CMS
- React, Vue, Next.js, SPA
Client-Side Enforcement
Leverages the visitor's `navigator` interface for real-time threat detection. This decentralized approach ensures protection without server-side overhead or complex WAF configurations.
Community Driven Registry
Our `agents.js` repository is a living document. We invite the developer community to contribute new signatures, ensuring the defense layer evolves as rapidly as the agents it blocks.
Sponsors & Developers
The humans defending the web.

How to install and how it works
⚙️ How it Works
AntiScrape operates as a lightweight client-side firewall. When you include our script, it executes immediately in the visitor's browser.
It checks the
navigator.userAgent string against our community-maintained registry of known
AI crawlers (OpenAI, Anthropic, Google Gemini, etc.).
If a match is found, the script stops page execution and replaces the entire DOM with a blockage screen, effectively preventing the bot from indexing or consuming your content.
📦 Installation
Add this single line to the
<head> of your website.
🚧 Experimental Project
This is an open-source experiment. AI companies frequently change their signatures. We cannot guarantee 100% protection or avoiding false positives. Use at your own discretion.
Registry of Blocked Agents
We actively monitor and block the following crawlers
