Frequently Asked Questions

Yes. Fluxzy is free and fully unlocked for personal use, with every feature available at no cost. The engine is open source, and the desktop app, CLI, and .NET packages can all be downloaded for free.

Fluxzy runs on Windows (7, 10, and 11 x64), macOS (both Intel and Apple Silicon), and Linux (Debian/Ubuntu .deb, Red Hat/Fedora .rpm, and AppImage). The CLI and .NET packages are fully cross-platform.

Every binary is published with a cryptographic checksum: SHA-256 for the desktop app and SHA-512 for the CLI. Click the fingerprint icon next to any download to copy its hash, then compare it against the file you downloaded. Desktop installers are also code-signed.

Yes. Windows installers and executables are code-signed with an Authenticode certificate, and macOS builds are signed and notarized by Apple. This means they run without SmartScreen or Gatekeeper warnings, and your operating system can confirm the binaries come from a verified publisher and have not been tampered with.

Use Fluxzy Desktop for an interactive interface to capture, inspect, and edit traffic. Use the CLI to automate captures, apply rules in scripts, or run Fluxzy on servers and in CI pipelines. Both share the same engine, so capture files are interchangeable.

Yes. The Fluxzy engine is open source and available on GitHub. You can review the code, build it from source, or embed it directly in your own .NET applications through the official NuGet packages.
