open source / free forever
An open-source AI agent that writes and edits scripts inside Roblox Studio. Genuinely free and unlimited - no API key, no credits, no subscription. It runs on your own free AI chat.
how it compares
The popular Roblox AI tools charge you per prompt. ZeroScript does the same thing - for free - because it runs on your own free DeepSeek, GLM, Kimi, Gemini, Qwen, Arena or Meta AI chat.

actually free
Most tools market a free tier, then gate you behind an API key you pay for, a credit meter, or a tiny prompt cap. ZeroScript is the one with no catch - because it rides your own free AI chat instead of a paid API.
| Tool | Its "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 your own paid Gemini API key |
| ZeroScript | Unlimited, forever | No catch - no API key, no credits, no subscription |
what it does

Opens, understands, and rewrites your Luau across the whole game tree.
Executes code directly in Studio to test ideas and fix bugs on the spot.
Creates meshes, materials and models, or inserts from the Creator Store.
Full awareness of instances and hierarchy for context-aware edits.
DeepSeek, GLM 5.2, Kimi K2.6, Gemini Flash, Qwen, Arena (multi-model) and Meta AI. Your own free chat, no API keys, no credits.
Starts and stops playtests so the AI can verify what it built.
