Choosing Your AI Assistant: Universal Support

Reviewing Supported AI Clients

Estimated reading: 0 minutes 8 views

GameCatalyst supports a wide range of AI clients, divided into two categories based on how they connect.

Desktop AI Clients (STDIO transport):

These clients run on your local machine and connect via standard input/output. They offer the lowest latency and highest reliability.

Claude Desktop — Anthropic’s local AI client with excellent coding capabilities
Cursor — AI-powered IDE built specifically for development
Windsurf / Cascade — Codeium’s AI IDE with strong multi-file editing
GitHub Copilot — Microsoft’s AI assistant in VS Code agent mode
Cline — VS Code extension with autonomous task execution
Roo Code — Another VS Code extension focused on code generation
JetBrains AI — Built into Rider, IntelliJ, and other JetBrains IDEs
Claude Code — Anthropic’s command-line AI tool
Augment Code — AI coding assistant with context awareness
Gemini CLI — Google’s command-line AI interface
Amazon Q Developer — AWS’s AI assistant for development

Cloud AI Clients (Web Relay transport):

These clients run in your web browser and need a public HTTPS connection. GameCatalyst provides the Vexstorm Web Relay for secure tunneling.

ChatGPT — OpenAI’s web-based AI (requires Developer Mode)
Claude.AI Online — Anthropic’s web portal
Devin — Cognition AI’s autonomous agent
Gemini Desktop — Google’s desktop AI (can use STDIO or Web Relay)

Which should you choose?

If you’re new to AI-assisted development, we recommend starting with Claude Desktop (free tier available) or Cursor (free trial available). Both are beginner-friendly, well-documented, and offer excellent GameCatalyst integration.

If you already use an AI client, stick with it. GameCatalyst adapts to your workflow.

Which client should you start with?

If you are new to AI-assisted development, we recommend starting with Claude Desktop. It has excellent coding capabilities, runs locally for low latency, and the STDIO connection is the simplest to configure. If you already use ChatGPT and prefer browser-based tools, that works too — you just need to start the Web Relay first.

Multiple clients at once:

You can connect multiple AI clients simultaneously. Each client gets its own independent session with its own project selection and permissions. You might use Claude Desktop for heavy coding work and ChatGPT for brainstorming and planning. Both connect to GameCatalyst at the same time without interfering with each other.

Switching clients:

Switching between AI clients is effortless. Your GameCatalyst setup does not change when you switch clients. The servers keep running. Your projects stay registered. Your configuration persists. You just connect the new client and start working. No reconfiguration needed on the GameCatalyst side.
