Why This Matters

Instant 1.0 introduces a scalable, open-source backend optimized for AI-coded applications, enabling developers to build and run unlimited real-time, offline-capable apps without the constraints of traditional hosting. Its innovative multi-tenant architecture and lightweight design significantly reduce costs and improve user experience, marking a notable advancement in backend infrastructure for AI-driven app development.

Key Takeaways

After 4 years, we’re releasing Instant 1.0!

[ 1 ] Instant turns your favorite coding agent into a full-stack app builder. And we’re fully open source.

Our claim is that Instant is the best backend you could use for AI-coded apps.

The constraints behind a real-time, relational, and multi-tenant backend pushed us towards some interesting design choices. We built a multi-tenant database on top of Postgres, and a sync engine in Clojure. We’ll cover how all this works and what we’ve learned so far.

Let’s get into it.

Demos

When you choose Instant you get three benefits:
