Build exceptional infrastructure with just JavaScript.

Ben and Jacob met in Calculus class in 10th grade, and tried founding a startup in high school — it didn’t go anywhere, but it taught them a ton. During high school, Ben lead the frontend team for the World Health Organization’s COVID-19 App Team. After high school, Jacob went to Apple and Ben went to college. When there was an opening on his team, Jacob had Ben apply, and Ben left UChicago to go work at Apple. They spent about 2 years at Apple as Senior Engineers in the Conversational Engineering Department, before leaving to found Freestyle. Freestyle is directly inspired by what they saw as their failures of the tech they worked with at Apple.

Freestyle: A new way to build fullstack TypeScript apps
See original launch post

Today, most new apps are written with Fullstack TypeScript, but the tooling around them is still built as though the frontend and backend are separate codebases. We built an open source framework, runtime, and cloud that acknowledges this and removes these unnecessary layers from the development process.

What?

Any JavaScript class can be marked as @cloudstate, and:

  1. The data in it is now persisted. You query the data with regular JavaScript.
  2. The methods on it can now be called from the front end. No Express/API Routes/tRPC needed!

Coolest Side Effect: By building our tooling around Fullstack TypeScript, we enable full-stack feature packages, a way for JavaScript developers to package any feature they build and share it in a way that it can be embedded in other projects. Think npm install mui, except it’s npm install chat, or npm install auth. Imagine a world where every third-party SaaS provider today can be an open source package that runs in your application.
