Instant turns your favorite AI into a full-stack app builder. You get auth, permissions, storage, presence, and streams — everything you need to ship apps your users will love. Free to use, 100% open source. and works well for both vibe coding and production apps! You can get started by simply running `npx create-instant-app` in the terminal or just add “Read getadb.com first” to any prompt

Been building apps for years, and Instant feels like magic.
That moment when you see your app running across multiple devices in real time? Those are the ones that matter. Instant gets you there in minutes.
Beyond the amazing stack, the team behind it are some of the kindest, hardest working people I've ever met. Joe and Stopa are really cooking.
Congrats on the launch!
Here's a screenshot of my first Instant app:

I've been using InstantDB for more than a year. The problems the product solves may seem "easy to do with x or y".. until you actually try to do it and discover the edge cases, perf issues etc. + the team is executing very fast.

I'm a huge instant fan -- the ability to have realtime + relational queries + true offline mode is a huge win for devs. (I'm one of the Firebase founders and the three of this together is HARD)
Kudos to the team for making a complex engineering challenge look effortless.
tried something similar a few months back — the hardest part wasnt getting auth working, it was the realtime sync when you have multiple tabs open. curious if instant handles that gracefully or if you still get the occasional race condition. either way the npx setup is slick, thats usually where i lose people when demoing
What if I have a product database with several million items? What about load handling in general?
