Welcome to Rindle

A simple and fast SQL database with live queries

execute("INSERT…")
execute("SELECT…")
execute("UPDATE…")
execute("DELETE…")
+subscribe("SELECT…")

Think Convex, but simple, open, and cheap. Turso, but with live queries.

Under the hood, Rindle is powered by a Rust port of ZVM, the incremental query engine behind Zero. ZVM blends ideas from traditional and incremental query engines, making live queries cheap enough to be on by default.

Features

  • Simple It’s SQL plus subscribe(). You already know how to use it: CREATE TABLE, INSERT, SELECT. Database, not framework.
  • Live Agents get woken on changes. Users see what happened without refreshing. Idle queries cost no CPU and ~400b of memory.
  • Fast First result in milliseconds, updates in microseconds. Thousands of live queries and thousands of writes/second on one core.
  • Tree queries One trailing WITH clause, and Rindle returns the tree of data your application actually wants, instead of a flat table to reassemble.
  • Composable Layer a sync client like @rocicorp/zero-client or TanStack DB on top for instant client-first reads and writes. Or run Rindle client-side only, as an embedded relational database with live queries.
  • Cheap Built to run on local NVMe with S3 as the log, so a database costs nothing when idle and almost nothing when active. Make one per app, one per agent, or let agents spawn their own.
