Our verdict on Fluxzy
Fluxzy is an HTTP/HTTPS debugging proxy for developers and security engineers who need to capture, inspect, alter, replay, and mock traffic. It supports proxy and proxyless capture, HTTP/1.1, HTTP/2, WebSockets, gRPC, Protobuf, and SOCKS5. Fluxzy Desktop runs on Windows, macOS, and Linux, while the product also includes a CLI, Docker image, .NET SDK, and Android traffic capture through Fluxzy Connect. The Community Edition exposes the full feature set for personal use, making Fluxzy suitable for individual development and investigation workflows.
Pricing is structured around free personal access and perpetual paid licenses. Community Edition costs €0 and includes full capture, inspection, and traffic-alteration features, along with breakpoints, the rule engine, decoders, and exports. Pro costs €49 per developer as a one-time purchase, adds lifetime access, clean traffic output, and removes the personal-use restriction; future updates are included for the purchased major version. Enterprise plans provide team licensing and centralized seat management: €59 per seat for 1–9 seats, €49 per seat for 10–49 seats, and €39 per seat for 50 or more seats. The upper tiers add volume pricing, while the smallest tier includes a single invoice.
Fluxzy’s strongest distinction is breadth across protocols, debugging actions, and development environments. Its feature set covers live request and response editing, rule-based transformations, custom response mocking, replay and resend, DNS spoofing, throttling, external proxy support, and traffic export. Integrations include Wireshark, major browsers, PowerShell, Node.js, Python, Ruby, Go, Rust, .NET, Docker, and .NET NuGet. Developers who want a wide protocol surface and multiple export paths should consider Fluxzy. Teams requiring shared licensing can use its Enterprise tiers, while users seeking an open-source proxy should choose an alternative because Fluxzy is proprietary.
