Obfuscate your .NET right in the browser.

01

Static, never run

BitMono rewrites the IL with AsmResolver. Your assembly is analyzed, never executed — safe by construction.

02

Nothing is kept

Your upload is deleted the instant it’s obfuscated, and the result is wiped the moment you download it.

03

The real engine

The same BitMono that ships on NuGet and runs in CI pipelines — not a watered-down web port.
