## What it is
ByeDPI (ciadpi) is a C program implementing various DPI (Deep Packet Inspection) bypass methods, running as a local SOCKS proxy server. It manipulates TCP/TLS traffic characteristics to evade censorship-based blocking.

## Use cases
- bypass DPI censorship blocks
- run a local SOCKS proxy that evades deep packet inspection
- unblock websites blocked by ISP traffic filtering
- circumvent TLS-based connection blocking
- proxy traffic through anti-censorship tricks like fake packets and TTL manipulation

## When to choose
- you need a lightweight native C tool to evade DPI-based blocking without a VPN
- you want a local SOCKS proxy with configurable bypass strategies (disorder, fake packets, TLS record splitting)
- your ISP uses deep packet inspection to block or throttle connections

## When to avoid
- you need a full VPN with encryption and authentication
- you want a GUI application rather than a command-line tool
- you need cross-platform mobile support or a browser extension
