FAQ

Questions, answered.

Is ZeroScript really free?

Yes — 100% free with unlimited prompts. No credits, no subscription. Runs on your own free DeepSeek, GLM, Kimi, Gemini, Qwen, Arena or Meta AI chat.

Do I need an API key?

No. Zero API keys, zero credits, zero subscription. That's kind of the point.

Why do I need to connect with Roblox?

Official Roblox OAuth verifies you're a real Roblox user and syncs your session. We never see your password — Roblox handles that. We only read your display name, avatar, and user ID.

Is it safe?

Fully open source under GPL-3.0. Connects only to Roblox Studio's official built-in MCP server, sends zero telemetry, runs locally on your PC.

Which AI models are supported?

Seven free options: DeepSeek (recommended), GLM 5.2, Kimi K2.6, Gemini Flash, Qwen, Arena, and Meta AI.

Do I need to know how to code?

No. Describe what you want in plain English — the AI writes and edits the Luau directly inside Roblox Studio.

Ready when you are

Stop paying per prompt.

Open source. Unlimited. Forever free.
