What NeoStack runs on
Engine versions and platforms for every surface, read from the releases we currently ship. The agent runs on your machine, so this is the list that matters before you install.
Unreal Engine plugin
The in-editor agent. Current release v3.1.41.
| Unreal Engine | Windows |
|---|---|
| UE 5.8 | Supported |
| UE 5.7 | Supported |

Editor-only plugin: it changes nothing about how your game packages or ships. Install it into your project’s Plugins/ folder — see the installation guide.

NeoStack Mobile
Watch sessions, answer permission requests, and pause a running goal from anywhere.

Agents and models
Use NeoStack Cloud, or bring your own: Claude Code, ChatGPT Codex, GitHub Copilot CLI, Gemini CLI, Cursor CLI, Grok, and Antigravity. API providers include OpenRouter, DeepSeek, Qwen, Groq, xAI, and the Vercel AI Gateway. Local models run through Ollama, LM Studio, vLLM, LocalAI, and llama.cpp — nothing leaves your machine when you use them.
Setup for each: choosing an agent.
