## What it is
Sheas Cealer is a WPF (.NET 8) Windows desktop tool that forges the SNI extension field in Chromium's launch parameters, allowing users to resist network eavesdropping and conduct network security research without a proxy. It ships with continuously updated forgery rules from the Cealing Host repository.

## Use cases
- defend against network eavesdropping without a proxy
- forge SNI values for Chromium-based browsers
- conduct network security research on SNI-based filtering
- keep browser host spoofing rules up to date
- access sites affected by SNI-based interference

## When to choose
- you are on Windows and want a GUI tool for SNI forgery with no proxy setup
- you want automatically updated host spoofing rules
- you need a lightweight alternative to full VPN/proxy solutions for anti-eavesdropping

## When to avoid
- you need a cross-platform solution (use Sheas Cealer Nix or Droid instead)
- you are not on Windows 10 or later
- you need a fully audited, licensed project (no explicit license file is provided)
- you need general-purpose proxy or VPN functionality rather than SNI spoofing
