Testimonials

What developers say

How teams put the Workbench tools to work

Pasted a callstack from a shipping build and got ranked root-cause suspects with engine-source references in under a minute. That used to be my whole afternoon.

Alex Merin

Gameplay Programmer

Falsepositive Games

Asset Tidy-Up found 12 GB of unreferenced textures and broken redirectors in our main branch. The per-category size report alone paid for the credits.

Northlight Interactive

I ask the knowledge base in plain English and get answers with citations to the engine source. It has basically replaced my UE-forums tab.

Ravi Chandran

UE Developer

Solo dev

Described a bulk-rename utility for our content browser in one sentence. Now it is a reusable tool our whole team calls from the agent.

Marta Weiss

Tools Programmer

Studio Redline

The whole thing runs over MCP — my coding agent hands the log to the Log Analyzer and has a fix drafted before I finish my coffee.

Karlsen & Co

No seats, no subscription. We top up credits when a milestone crunches and spend them per run — finance actually likes this model.

Frequently asked questions

What is Spaghetti?
Spaghetti (spaghetti.gg) is the Unreal AI Workbench — a set of AI tools for Unreal Engine development that you drive through the AI client you already use (Claude Code, Cursor, opencode) over the Model Context Protocol. It analyzes engine logs, audits project assets, generates reviewed editor scripts, and searches engine documentation.
How much does it cost?
There is no subscription. You pay per tool call with prepaid credits — 100 credits = $1; billed tools charge a fixed price per call and only on success or your approval, while research and documentation tools are free. New accounts start with 100 welcome credits, no payment method required.
Which AI clients can I use it with?
Any client that speaks the Model Context Protocol. Sign-in is first-party OAuth — on first connect your client opens a browser where you sign in with your Spaghetti account; no API keys sit in your client config.
Is my project data safe?
Nothing is collected passively — tools run only when you ask. Log and asset files upload directly to object storage via a presigned link scoped to that session (expires in 15 minutes) and never pass through the chat or model context; the UE connector makes zero outbound network calls, and generated editor scripts become real only after your approval, with destructive operations commented out. Parsed log events are stored with emails and tokens redacted to power the research tools.
Which Unreal Engine versions are supported?
The cloud tools work with any Unreal Engine project. The optional UE connector plugin integrates with Unreal Engine 5.8 and newer, registering its asset-inventory tool on the engine's built-in MCP server.
