Eudaimonic Inc.

Company

We build DeepSpace — the app engine.

A real-time, collaborative platform and SDK for shipping full-stack apps without the infrastructure work.

What we do

DeepSpace is a real-time application platform and developer SDK. We handle the infrastructure that every app rebuilds from scratch — auth, database, realtime sync, file storage, scheduled jobs, AI integrations, hosting — so builders can focus on the product itself.

The problem we solve: AI made it dramatically cheaper to write code, but the cost of turning code into something people can actually rely on hasn't moved. Most prototypes die between “works on my laptop” and “multi-user app on the internet.” DeepSpace closes that gap.

Our customers are developers shipping real-time and collaborative apps — and builders who want a hosted platform where apps work instantly across web and mobile, with users, payments, and discovery built in.

DeepSpace SDK

Public · npm

A full-stack framework for shipping real-time, secure, scalable apps to a custom domain in minutes. One package bundles auth, realtime data subscriptions, RBAC, messaging, file storage, collaborative editing (Yjs), cron, and agentic chat. Apps run on Cloudflare Workers + Durable Objects with zero-config deployment. Designed for both human developers and the agents writing code on their behalf.

  const { create, put } = useMutations<Todo>('todos')

  return <ul>
    {records.map(r => (
      <li key={r.recordId}
          onClick={() =>
            put(r.recordId, { done: true })}>
        {r.data.title}
