What is it?

Laf is an open-source cloud development platform that bundles cloud functions, a cloud database, file storage, website hosting and WebSocket support. Functions are written in JavaScript or TypeScript directly in a web-based IDE and published with one step, so developers can focus on application logic instead of server setup.

The platform provides a client SDK for calling functions from any JavaScript runtime, which lets frontend developers build backend features without learning a separate server stack. Static front-end builds can be deployed alongside the functions. Self-hosting is supported on Kubernetes, and the project is designed so teams can deploy it on their own infrastructure and deliver the source code to customers.
