Miasma

Miasma is an open-source Rust-based server designed to fight back against AI web scrapers that harvest website content without permission. It works by serving poisoned training data alongside self-referential links, trapping scrapers in an infinite loop of low-quality "slop" data. The tool is extremely fast and memory-efficient, making it practical to run alongside your existing web infrastructure without significant resource overhead.

• Poisoned data delivery: Miasma proxies content from a configurable poison source and serves it to scrapers, contaminating their training datasets.
• Self-referential link trapping: Each response includes multiple hidden links pointing back to Miasma, keeping scrapers looping indefinitely.
• Hidden link embedding: Add invisible HTML links to your site that only scrapers can see, funneling them into Miasma without affecting human visitors or accessibility tools.
• Reverse proxy integration: Works seamlessly with Nginx and similar reverse proxies — configure a path like /bots to route scraper traffic directly to Miasma.
• Configurable connection limits: Set a maximum number of in-flight requests (--max-in-flight) to cap memory usage; excess requests receive a 429 response immediately.
• Gzip compression support: Optional --force-gzip flag compresses all responses regardless of client headers, helping reduce egress bandwidth costs.
• CLI configuration: All options — port, host, link prefix, link count, poison source URL — are controlled via simple command-line flags.
• robots.txt guidance: Built-in documentation helps you protect legitimate search engine bots (Googlebot, Bingbot, etc.) from being caught by Miasma.
• Install via Cargo: Run cargo install miasma to get started instantly, or download a pre-built binary from the GitHub releases page.
• GPL-3.0 licensed: Fully free and open-source; contributions are welcome, though primarily AI-generated pull requests are automatically rejected.
