Take back what’s yours.

Take back what’s yours.

Big tech owns your online life. We've traded privacy for convenience, entrusting our personal data to closed systems that don't work together.  We are turning the tables and giving all power back to the user with a new technological foundation for truly decentralized collaboration.

Why do we need change?

What is changing?

Take collaboration into
your own hands.

We eliminate intermediaries. You individually decide with whom you want to share your data and under what conditions. CO lives on your local device and is directly synced only with your peers over the network. All apps are built on this fundamental concept.

Their game
Your game

Nobody can see what’s inside, except for you & your peers

Nobody can block you from accessing your data

Nobody can mediate the connection between your devices


Groundwork for a new digital world

One technological foundation
 for a better digital life.

Limitless possibilities are built upon this fundamental concept, while we’re just updating the underlying technological foundation without changing how you interact with your favorite apps.

A leading example for the new technology

Build great apps

without a backend

With COKIT, developers can build on top of our foundation, bringing more diversity and fresh ideas to the ecosystem. Establish data ownership and app interoperability as the standard for every digital user.

app.tsx
import { useCo } from "co";

const ShoppingList = () => {
  const [state, actions] = useCo(
    "3c085622-a175-4357-ace9-c59443404794"
  );

  return (
    <List>
      {state.items.map(({ item }) => (
        <ListItem onClick={actions.markAsDone({ id: item.id })}>
          {todo.title}
        </ListItem>
      ))}
    </List>
  );
}
schema.ts
import { CoUUID, CoList, Co } from "co/core";

export interface ShoppingListItem {
  id: CoUUID;
  title: string;
  done: boolean;
}

export interface ShoppingList extends Co {
  items: CoList<ShoppingListItem>;
}
actions.ts
import { defineReducer, uuid } from "co/core";
import { ShoppingList } from "./schema";

export const actions = {
  addItem: defineReducer((state: ShoppingList, { id, title }) => {
    state.items.push({ id, title, done: false});
  }),
  markAsDone: defineReducer((state: ShoppingList, { id }) => {
    state.items.updateOne(
      (item) => item.id == id,
      (item) => item.done = true,
