⁠crapify

crapify is a proxy for simulating slow, spotty, HTTP connections. It allows you to vary:

• the upload and download speed of requests.
• the maximum number of concurrent outbound HTTP connections.
• the number of bytes dropped during transfers.

Contribute to Crapify on GitHub⁠

⁠Usage

• npm install crapify -g
• crapify start --port=5000 --speed=3000 --concurrency=2, where:
  • port is the port crapify should start on.
  • speed is the connection speed in bytes/second.
  • concurrency is the number of concurrent outbound connections allowed.
  • drop-frequency is how often bytes should be dropped (byte count % drop frequency).

⁠Docker

• To build your image use: docker build . -t crapify:latest
• docker run -d -p 5000:5000 crapify. You can specify every crapify options thru env variables, eg:
  • docker run -d -p 5000:5000 -e SPEED=3000 -e CONCURRENCY=2 crapify
