What you need besides the app: AI, Roblox Studio, computer

The app is not enough on its own. You need a computer that can handle the load, Roblox Studio, and an AI account that you pay for with its provider. This page lists these requirements, and separates the three costs that customers most often confuse.

A compatible computer

VibeStarter runs your agents in an embedded Linux virtual machine. This is what sets the requirements.

Requirement	Windows	Mac
System	Windows 10 or 11, 64-bit	macOS 15 or later
Processor	x86-64 Intel or AMD	Apple Silicon, M1 or later
Not supported	Windows on ARM (Snapdragon, Copilot+)	Intel Mac
Logical cores	2 minimum, 8 or more recommended	2 minimum, 8 or more recommended
Memory	6 GB minimum, 16 GB or more recommended	6 GB minimum, 16 GB or more recommended
Free disk space	5 GB minimum, 20 GB recommended	5 GB minimum, 20 GB recommended
Virtualization	VT-x or AMD-V (“SVM”) to enable in the BIOS/UEFI	Built into the system, nothing to enable
Connection	Internet at all times	Internet at all times

What the app says about memory on first launch:

Less than 6 GB: the app does not start.
6 to 7 GB: this is risky.
8 to 15 GB: this is enough, but several agents at once will be tight on memory.
16 GB or more: recommended.

Without hardware virtualization, the app still starts, using software emulation, and says so: “Acceleration inactive: reduced performance and new Blender computations unavailable.” Agents are much slower, and creating models with Blender is suspended. On Windows, the app tells you which feature to turn on.

The screen-by-screen details are in Check that your computer is compatible.

Roblox Studio and a Roblox account

Roblox Studio remains the editor for the 3D world, and the only place where your game is published. VibeStarter controls it; it does not replace it.
The VibeStarter Sync plugin is installed in Studio by the app, after you give your explicit agreement during setup. You don’t need to install or turn on anything in Studio’s menus.
An open place in Studio is needed to see the code arrive and for agents to act in the game. Without one, the project still opens, with Continue anyway.
Your Roblox account is linked to VibeStarter so the app can publish assets on your behalf.
An Open Cloud key is only needed for Game Passes and developer products. Note: a Roblox key expires after 60 days without use.

See Link VibeStarter to Roblox Studio and Link your Roblox account and your Open Cloud key.

The three costs not to mix up

Cost	What it pays for	Paid to	Frequency	Required?
The app purchase	Access to VibeStarter for life, updates included, the training and the members’ Discord	VibeStarter	One time only	Yes
Your AI subscription	The thinking work of your agents: reading, writing and fixing code	The AI provider (Anthropic, OpenAI, xAI, Google…)	Depends on the provider	Yes: without it, no agent works
VibeStarter credits	Asset generation: images, icons, 3D models, music, sound effects, model splitting	VibeStarter	Monthly subscription, or top-up packs	No

1. The app purchase

As of September 17, 2026: €147 incl. VAT for one access (Solo plan), €220 incl. VAT for two accesses (Duo plan), payable in three installments with no fees. The total does not change, and there is no extra charge. The official prices are on vibestarter.pro/pricing.

Paying in three installments is a spread-out purchase, not a subscription: there is nothing to cancel, only installments to finish paying.

There is no free trial, no demo, and no limited version.

Details and steps: Buy VibeStarter.

2. Your AI subscription

Each agent uses your account with its provider. You choose which one; you can switch.

Agent	What you need
Claude Code	A Claude subscription (Pro or Max), from Anthropic
Codex	A ChatGPT subscription (Plus or Pro), from OpenAI
Grok Build	A Grok subscription, from xAI. Native image tools require a compatible xAI plan
Antigravity	A Google account. Daily agent use is free, no credit card required
OpenCode	The provider of your choice, set up in OpenCode. The app recommends the OpenCode Go subscription

You sign in through each provider’s official tool. The app says so in its settings: “VibeStarter never sees your tokens.”

To choose: Which AI subscription to pick, and how to make your quota last. To connect: Connect your AI account.

3. VibeStarter credits, or your own keys

Credits pay for asset generation, never for the agents’ reasoning. Two ways to get them, as of September 17, 2026:

The VibeStarter Plus subscription, at €29 per month for 2,000 credits per month. Monthly credits reset at each renewal: unused credits do not roll over.
Pay-as-you-go packs: 400 credits for €10, 1,000 for €25, 2,000 for €50. They do not expire, work without a subscription, and are used after the monthly credits.

There is also a Pro tier: same features as Plus, with a larger credit volume. The official amounts are on vibestarter.pro/pricing.

A third option, free on the VibeStarter side: bring your own API keys (Gemini, Meshy, ElevenLabs) with the I use my own API keys button. Your generations then run on your accounts, and are billed by those providers.

See AI credits in practice and The VibeStarter Plus and Pro subscription.

Frequently asked questions

Once VibeStarter is bought, what is left to pay? An AI subscription, always. Then, only if you want asset generations, VibeStarter credits or your own API keys.

Can I start without any extra AI spending? Antigravity gives you free daily agent use with a Google account, no credit card needed. It is the only free option among the agents we ship.

Does VibeStarter Plus replace my Claude subscription? No. Plus gives you credits for assets. It does not write a single line of code.

I have a Mac. Does it work? Yes, if it is an Apple Silicon Mac running macOS 15 or later. Intel Macs are not supported.

I’m switching computers. Do I need to buy again? No. Reinstall the app and sign in with the same account. See Switch computers.
