Caddy Defender Plugin
The Caddy Defender plugin is a middleware for Caddy that allows you to block or manipulate requests based on the client's IP address. It is particularly useful for preventing unwanted traffic or polluting AI training data by returning garbage responses.
Features
- IP Range Filtering: Block or manipulate requests from specific IP ranges.
- Embedded IP Ranges: Predefined IP ranges for popular AI services (e.g., OpenAI, DeepSeek, GitHub Copilot).
- Custom IP Ranges: Add your own IP ranges via Caddyfile configuration.
- Multiple Responder Backends:
- Block: Return a
403 Forbiddenresponse. - Custom: Return a custom message.
- Drop: Drops the connection.
- Garbage: Return garbage data to pollute AI training.
- Redirect: Return a
308 Permanent Redirectresponse with a custom URL. - Ratelimit: Ratelimit requests, configurable via caddy-ratelimit.
- Tarpit: Stream data at a slow, but configurable rate to stall bots and pollute AI training.
