Coplay Unity Plugin

Coplay is an AI agent that runs inside the Unity editor and carries out game development tasks on request. Developers describe what they want to build or fix in natural language, and Coplay handles scripting, scene setup and other tedious engine work, proposing changes that can be previewed, edited and applied. It installs through the Unity Package Manager and supports Unity 2022 and newer. It serves solo creators, indie developers and studios. The level of autonomy is adjustable: developers can approve every change or let the agent complete tasks on its own. Users can choose among the major AI models, and Coplay MCP can be used for free with an existing AI subscription. Inside the app, the cost of each message, tool call and full conversation thread is shown, and failed tool calls are not charged. Pricing is published. Free costs $0 per month and includes access to all Coplay features and all models. Professional costs $20 per month and includes $20 of credits per month, an extra $20 of credits per month for Claude models, a $4 daily credit for Claude models when the balance reaches zero, access to the latest models, unlimited top ups and priority support. Credits are charged at LLM provider cost with no markup. Enterprise is custom and adds VPC installation, a usage and access dashboard, enterprise support, no training on customer data and air gapped local deployment. Coplay is now part of Aura, an AI assistant covering both Unity and Unreal Engine, which offers larger plans under one subscription. Coplay is not affiliated with or endorsed by Unity.
