Is there a free trial?

Yes. Start a free 3-day trial from your account at codefizz.dev/account, no credit card required. The trial unlocks the full Pro plugin for UE 5.6, 5.7 and 5.8 on one machine. When it ends, upgrade to a paid plan and the same key keeps working with five machine seats. There is also a separate free, open-source community edition (Unreal MCP).

Which Unreal Engine versions are supported?

UE 5.6, 5.7 and 5.8 on Win64. Each release ships as a separate binary plugin matched to the engine ABI, and the cfa CLI downloads the build that matches the engine you point it at. Future engine versions are added as they release.

Which platforms are supported?

Right now, Windows 64-bit only. The plugin is built and tested on Windows for this first release. Linux and Mac support are on the roadmap and will be added when there is clear demand from paying customers. I would rather wait until I can properly test those builds end to end than ship binaries I have not run myself. If you are on Mac or Linux and would buy the plugin today, drop a note in Discord or send me an email. That is how the priority for adding those platforms gets set.

Do I need a license key, and how do I enter it?

Activate from the CLI with your CodeFizz website account. Install or update the free cfa CLI, run cfa login, and sign in in the browser. That machine is activated and the editor plugin reads the same sign in, with nothing to paste inside Unreal. Offline grace still applies. A license key remains under License and billing for recovery and older cfa builds (cfa login --key), but new setups should use browser login only.

What MCP clients work with the plugin?

Any MCP-compatible client. The plugin exposes a TCP bridge and the Go CLI ships separately, so Claude Code, Cursor, VS Code, Gemini, and other MCP hosts all work out of the box.

Can I cancel anytime?

Yes. Open your account at codefizz.dev/account and click Manage billing to open the Polar billing portal, then cancel in one click. You keep access through the end of your billing period and stop being charged afterward.

What happens to my installed plugin if I cancel?

A subscription earns you ownership, not just access. Once you have paid for twelve months, the version you have at that point is permanently yours: cancel any time after that and it keeps running on your machines with nothing more to pay, you simply stop receiving new releases. Annual plans reach that point with their first payment, since they cover a year up front. Before twelve months your access runs alongside the subscription, so it pauses if you cancel and picks straight back up when you resubscribe, with the months you already paid still counting toward the permanent license. Lifetime Pro skips the wait entirely and is the only plan that never stops receiving updates. Anyone who subscribed before 5 August 2026 keeps their original terms.

Do you offer refunds?

No refunds on subscriptions, since the plugin is downloadable software you get immediately. You can cancel any time and keep access through the end of the period you have already paid for. Lifetime Pro is a one-time purchase with nothing to cancel: it is fully refundable within fourteen days if you have not downloaded the plugin yet, and a refund ends the licence. If you ran into a real bug or a feature you reasonably expected to be there, email me and we will figure it out. Full policy on the Refund Policy page in the footer.

Why is Patron more expensive when I get the same plugin?

Patron is for people who want to influence the direction of CodeFizz Editor Agent, with voting, a private roadmap, priority answers, and direct input on new APIs. If you just need the plugin and updates, stay on Pro.

Is there a free version?

Yes. There is a free, open-source community edition (Unreal MCP) that gives you the core bridge and a basic command set, which is great for trying the workflow. The paid Pro edition is the fully maintained build with the complete toolset (Niagara, PCG, StateTree, Insights, and more), regular updates, and support. The open-source edition is linked in the footer.

Studio / team licensing?

For studios needing multiple seats, an enterprise tier is available off-platform. Contact directly for pricing.

Is there a lifetime or one-time payment option?

Yes. Lifetime Pro is a one-time payment of $399 USD (list price $499) that gives you the full CodeFizz Editor Agent plugin and every future update permanently, with no subscription and nothing to renew or cancel. It covers UE 5.6, 5.7 and 5.8 plus engine versions added later, five machine seats, and Pro Discord access. Prices are localized, so you are charged in your own currency at checkout.

What does Lifetime Pro include?

Lifetime Pro is the complete Pro plugin for every supported Unreal Engine version, yours permanently. That means all 900+ commands across Blueprints, Materials, Niagara, PCG, StateTree, Control Rig, Mutable, audio and Insights profiling, every future update and every new command at no extra cost, five activated machines, and Pro Discord channel access. There is no renewal date, no expiry, and no second invoice. You pay once and it keeps working, including on Unreal Engine versions that do not exist yet.

Fix: the CodeFizz panel does not show Active

The editor panel does not read Active, or a command says this machine is not licensed. Check with cfa whoami, sign in with cfa login, and read what each panel state means: not activated, signed out, reconnect needed, trial ended, subscription ended.

The CodeFizz panel inside the Unreal Editor does not read Active, or a command reports that this machine is not licensed. There is nothing to paste inside Unreal: the editor plugin reads the same sign-in the CLI wrote.

Check this machine's sign-in

See who is signed in on this machine and when it expires:

bash

cfa whoami

If that reports you are not signed in, activate the machine and press Refresh in the editor panel:

bash

cfa login

What the panel is telling you

Not activated. No sign-in on this machine yet. Run cfa login, then Refresh.

Signed out. This machine was deactivated from your account, or from another machine with deactivate-all. Run cfa login again to reclaim a seat.

Reconnect needed. The offline grace window ran out. Connect to the internet and it refreshes on its own, or press Refresh.

Free trial ended, or subscription ended. The trial has expired or the subscription lapsed. See pricing.

If you are out of machine seats

A paid licence covers five of your own machines. Signing in again on a machine you already use never takes a second seat.

Free the seat on the machine you are using now:

bash

cfa logout

Free every machine at once, then sign in again where you need it:

bash

cfa deactivate-all
