Open the demo

surreal-demo.ventstream.dev — no signup, nothing to install.
Every card on that page is a composed document in SurrealDB: an order row joined with its customer and its items, kept in sync by VentStream as three normalized Postgres tables change. Your browser holds a SurrealDB LIVE SELECT over a WebSocket — no polling, no replay. When a document changes, SurrealDB pushes it to you the moment VentStream writes it.

​
What to try

  1. Place an order. Your click gets a tag like #7f3k. The button writes plain SQL to Postgres — and the composed document comes back through the whole pipeline carrying your tag, with the measured commit-to-browser latency next to it. Typically under half a second.
  2. Boost a customer’s tier (left panel). This updates one row in the customers table — and every order document embedding that customer re-composes at once. Those cards flash blue: that’s join fan-out, the hard part of keeping denormalized views honest.
  3. Cancel an order. The delete tombstones through and the card fades out.
  4. Watch the terminal in the header: those are the actual SQL statements hitting Postgres, including yours.

​
How it works

The pipeline is declared in one config: a Postgres source, a joins spec composing orders + customers + order_items, and a SurrealDB sink. The engine runs fleet-managed — the same demo you’re clicking is a pipeline in our own dashboard, deployed with an agent key like any customer workload. The browser connects as a SurrealDB user with a read-only VIEWER role; writes only ever flow through the pipeline.

Run this yourself

The SurrealDB sink guide walks the same shape from zero: provision, one config file, one command, live documents.
