Great question. They solve different problems.

Vector DBs are great for retrieval: "find relevant chunks to add to the prompt." But they're not designed for state management. When you update a message, there's no version history. When something breaks, you can't rewind to see exactly what the agent saw.

UltraContext manages the structured context (conversation history, tool calls, system prompts) with git semantics. Fork, rewind, merge. You can't git revert a vector embedding.

They're complementary. You'd use a vector DB to decide what goes in the context, and UltraContext to manage what's already there.
