Full breakdowns: vs Lemonade.gg · vs Luamotion
Every "free" Roblox AI has a catch.
Free tier → paywall → credit meter → pay $20/mo. ZeroScript is the exception.
| Tool | The "free" tier | The catch |
|---|---|---|
| Lemonade.gg | 4 prompts | Then $20/month for 100 |
| Luamotion | Free to start | Runs on paid credits |
| RoCode | 50k tokens / 15 hrs | Then $9.99–$24.99/month |
| PerfectLua | 10 Sparks / month | Then $12.99+/month |
| Developer Intelligence | Free plugin | Needs paid Gemini API key |
| ZeroScript | Unlimited, forever | No catch. Really. |

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.
