Deep Dive: Switching from BoltAI to Open WebUI
Trade-offs, installation & data architecture
What you trade away
It is a web service you must administer, so it lacks BoltAI's native Mac feel and zero-server single-user convenience.
How to deploy Open WebUI
Run the official Docker image, install the Python package, or deploy with Kubernetes
What it takes to run
A non-expert must install Docker or a compatible Python environment, mount persistent storage correctly, and separately provide Ollama or an API endpoint
Where your data lives
By default, chats and account data live in a local SQLite webui.db, uploads in a data/uploads directory and embeddings in the configured vector store; PostgreSQL and object storage are optional
Why fork Open WebUI instead of vibe-coding a BoltAI clone?
A coding agent can one-shot a basic chat window that calls a few AI APIs. That reproduces only a small part of BoltAI. A credible replacement must remain fast with large histories and active streams, combine SwiftUI with purpose-built AppKit components where the framework falls short, and make focus, keyboard navigation, menus, windows, drag and drop, and global shortcuts behave like a real Mac app. It must also reproduce AI Workflows, Instant Chat, Instant Dictation, attachments, tools, provider-specific behavior, local persistence, sync recovery, and protected credentials. These are interacting product systems, not a collection of generated screens.
