This is why I built https://db4.app. This solves the biggest hurdle with using a PGLite instance from your browser, by giving you a universal postgres url. You can connect to it from anywhere with your credentials. Your data and queries are fully encrypted end-to-end. So it is only between your app, and your browser tab. Your data stays with you and db4.app provides the relay basically.

You can also host the Relay app yourself locally, if you'd like.

It comes with support for PG-vector, so you can use it for RAG in LLM Studio. We have a few MCP applications already built in the community apps section.

Happy to answer any questions.
