Frequently asked questions

Yes. You can start a free 3-day trial from your account at codefizz.dev/account, with no credit card required. It unlocks the full Pro plugin for UE 5.6, 5.7 and 5.8 on one machine so you can try the real workflow. When the trial ends, the plugin and CLI pause until you subscribe; if you upgrade, the same key is promoted in place to a paid key with five machine seats, so nothing to re-enter. There is also a separate free, open-source community edition (Unreal MCP) linked in the footer if you just want the basics for free forever.

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.

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.

You activate from the CLI with your CodeFizz website account, not by pasting a key into Unreal. Install or update the free cfa CLI, then run cfa login. It opens your browser so you sign in with the same account (Google, GitHub, Discord, or email). That machine is activated and the editor plugin reads the same sign in. Offline grace still applies. A license key still exists under License and billing for older cfa builds and recovery (cfa login --key), but new setups should use browser login only.

Everything goes through the free cfa CLI. Create or sign in at codefizz.dev/account (Google, GitHub, Discord, or email). Start a trial or subscribe. Install cfa with PowerShell (recommended: irm https://codefizz.dev/install.ps1 | iex) or npm install -g codefizz-editor-agent. Run cfa login so your browser authorizes this machine with that account. Then cfa install-plugin with a path to your engine or project, for example cfa install-plugin "E:/Unreal/UE_5.8". The editor plugin shows Active with nothing to paste. The in editor panel is read only: status plus Refresh.

Your paid license works on up to 5 of your own machines, which is plenty for a desktop, a laptop, and then some. You will almost certainly never reach it. The limit is there to stop a license being shared publicly, because paid seats keep this one developer project alive. Manage seats from the CLI: cfa logout frees this machine, and cfa deactivate-all frees every machine at once. Signing in again on the same machine never uses a second seat. If something leaked, regenerate the legacy key on the account page or email contact@codefizz.dev, then run cfa login again on each machine.

Each command talks to exactly one editor. Run cfa list_editors to see every running editor with its project, engine, port, and process id, then cfa connect <project> to choose one for the commands that follow. The choice is saved, so it carries across separate terminals. If the choice is ambiguous, the CLI refuses and lists the editors instead of editing the wrong project. With a single editor open, or when your terminal is inside the project folder, it routes automatically. cfa health_check also reports which editor it reached so you can confirm.

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.

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.

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.

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.

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.

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.

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

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.

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.
