Instant 1.0, a backend for AI-coded apps (instantdb.com) AI

Instant 1.0 is an open-source backend for “AI-coded” app builders, positioning itself as a multi-tenant Postgres-based alternative that removes the need to manage per-app infrastructure. The article explains how Instant provides a built-in sync engine for real-time multiplayer, offline support, and optimistic updates, plus integrated services like auth, file storage, presence, and streaming. It also outlines the system architecture, including a client SDK that handles offline/optimistic behavior, a Clojure backend that manages real-time query updates and services, and a logically separated multi-tenant database layer on top of Postgres.
