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
