Yes. The Community edition is free and includes every capture, inspection, and traffic-alteration feature: raw packet capture, breakpoints, the rule engine, the decoders, and the exports. There is no trial period, nothing locked behind a paywall, and no telemetry. Two things set it apart from a paid license: intercepted requests carry a small x-fluxzy-community header, and the Community edition is intended for personal use. For commercial or client work, see the next question.

A license removes the x-fluxzy-community header from intercepted traffic and lifts the personal-use restriction, so you can use Fluxzy in professional and commercial contexts. The feature set is identical to the Community edition. You are paying for clean output at work and to support continued development, not to unlock features.

When the Community edition relays a request, it adds an x-fluxzy-community header so the receiving server can tell the traffic passed through the free edition. It does not change how Fluxzy captures or displays anything locally. A paid license removes it, which matters when you test against systems that inspect or log request headers, or when extra headers are not acceptable on client work.

A one-time purchase. You pay once and the license does not expire. There is no recurring fee and no auto-renewal.

Minor and patch updates are free for the version you bought. Future major versions may be a paid upgrade. The current major version, Fluxzy v2, is a long-term support release: it receives maintenance and fixes until March 2028, so a v2 license stays current and supported for years with no further payment.

Every license is meant for one person, who can install and use Fluxzy on as many machines as they need: a work desktop, a laptop, a personal computer. Sign in with your Fluxzy account on each machine. There is no device limit and no activation key to move around. The Pro (Perpetual) license is licensed per developer; the Enterprise (Perpetual) license is licensed per seat, with one seat assigned to each team member.

The Enterprise (Perpetual) license covers a whole team with one purchase, a single invoice, and centralized seat management. Per-seat pricing is tiered, so the price drops as the team grows: 59 EUR per seat for 1 to 9 seats, 49 EUR for 10 to 49, and 39 EUR for 50 or more. Enterprise customers can also arrange custom support on a per-seat basis. Get in touch through the contact page to set this up.

Yes. If Fluxzy does not work out for you, contact us within 14 days of purchase for a full refund. Since the Community edition already exposes every feature, we recommend trying it first so you know exactly what you are buying.

Fluxzy is built on a modern streaming interception engine with first-class HTTP/2, WebSocket, and SOCKS5 support, raw PCAPNG capture with embedded TLS keys, decoders for JWT, gRPC, and LLM API calls, and a YAML rule engine you can version-control and run headless. The same engine powers the desktop app and the CLI, so what you build interactively also runs in automation. The Community edition lets you compare Fluxzy on your own traffic at no cost.

Yes. Decrypting HTTPS requires a trusted root certificate, which is how TLS interception works for any tool. Fluxzy keeps it straightforward: one-click certificate installation, browsers and terminals that launch already configured, and guidance for mobile devices. You can also supply your own root CA, or skip decryption for hosts you do not need to inspect.

Fluxzy.Core, the interception engine, is open source under the GPLv3 license and published on GitHub and NuGet. You can audit how traffic is intercepted and build on top of it. The Fluxzy Desktop application is free to use but is not open source.

Fluxzy.Core is published under the GPLv3 license, which requires any application built on it to be released under a compatible open-source license. If you want to embed Fluxzy.Core in a proprietary or closed-source product without the GPLv3 obligations, a separate commercial license is available. Get in touch through the contact page to discuss it.
