Understanding No Vendor Lock-In

One of GameCatalyst’s core design principles is vendor neutrality. You’re never locked into a specific AI provider or client.

What “no vendor lock-in” means:

• Switch clients anytime — Connect Claude Desktop today, switch to ChatGPT tomorrow. Your GameCatalyst setup doesn’t change.
• Use multiple clients simultaneously — Connect Claude Desktop for coding and ChatGPT for brainstorming. Both work with the same Unity project.
• No proprietary formats — GameCatalyst uses the open Model Context Protocol (MCP). Any MCP-compatible client can connect.
• No subscription required — GameCatalyst itself doesn’t require a subscription. You only pay for your AI client (if applicable).

How GameCatalyst achieves this:

GameCatalyst implements the Model Context Protocol (MCP), a standardized communication protocol for AI tools. MCP is like USB for AI assistants — it’s a universal standard that any client can implement.

When you connect an AI client, GameCatalyst doesn’t care which brand it is. It just checks:

1. Does the client speak MCP? (Yes/No)
2. Is the client authenticated? (Session fingerprint)
3. Which project did the user select? (Explicit selection required)

If those checks pass, the client gets access to GameCatalyst’s tools. The client’s brand, pricing model, or underlying AI model doesn’t matter.

Practical benefits:

• Try before you commit — Test GameCatalyst with free AI clients before paying for premium ones
• Use the best tool for each task — Some AI models are better at certain tasks. Use whichever works best.
• Future-proof — When new AI clients launch, they’ll work with GameCatalyst if they support MCP

You own your workflow. GameCatalyst just makes it better.

Why this matters long-term:

The AI landscape changes fast. New models launch every month. New clients appear constantly. If GameCatalyst locked you into one provider, you would miss out on better tools as they emerge. Because GameCatalyst uses the open MCP standard, every new MCP-compatible client works automatically. You never get stuck on yesterday’s technology.

Multiple clients at once:

You can connect several AI clients simultaneously. Each gets its own independent session with separate project selection and permission state. Use Claude Desktop for deep coding sessions and ChatGPT for brainstorming in a browser tab. Both connect to the same GameCatalyst installation without interfering with each other. Switch between them freely — your servers keep running, your projects stay registered, and your configuration persists across client changes.
