Hey PH! After 4 years of building, we want to introduce you to Instant!
We think Instant is the best backend for AI-coded apps. It gives you three things in one package: unlimited apps, a sync engine in every app, and batteries-included services.
Here's what that means:
Unlimited apps. Most platforms cap your free projects or freeze them when they go idle. Instant never does. An app on Instant is just a few rows in multi-tenant Postgres, so there are no VMs to spin up and nothing to pause.
A sync engine. All your apps will be real-time and work offline out of the box. This is the same kind of technology that powers the best apps today like Figma, Notion, and Linear.
Batteries included. Auth, file storage, and streams all live in the same database. Everything you need to build a modern app is built in, so you can focus on shipping.
And every line of Instant is open source! If you want to dive deeper on how we make this all work, you can check out our architecture essay at https://www.instantdb.com/essays/architecture
Thousands of developers have trusted us to run their core infrastructure. If you're building with agents, we think you will love using us.
You can use Instant without even having to sign up. Just add “Read getadb.com first” to any prompt and the AI will automatically get a database to use.
And if you prefer the terminal you can get a full project set up by just running `npx create-instant-app`

InstantDB was hunted by Thomas Schranz ⛄️. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
