About Simulfy.Digital Enthusiasts. Creative People

Simulfy is the fastlane for developers to build real time, shared state, multi user apps and sites, using JavaScript. The name Simulfy is derived from the word simultaneous; it allows your users and apps to simultaneously exchange and edit your self defined data structures in real time. After more than a year of steady development we're ready to let you test-drive our platform.

Real-time, offline capable

Simulfy is offline capable. We support both synchronous and asynchronous communication out of the box. All incoming and outgoing updates on data will be communicated in real-time to all connected clients. When there's no connection, your changes are buffered and merged when the connection is back.

Who is it for?

Simulfy is for app or website developers who want to integrate real-time simultaneous collaboration to their own or clients websites or apps.

How does it work?

The core of our platform is a web-based distributed database for JSON like document structures. Using our Simulfy JavaScript Client API you can start defining your own content structures and let your users and apps access and edit this data collaboratively and in real-time.

We'll release more in-depth information soon!
