I Built Your Personal Software Ecosystem

What if you had your own npm registry, your own GitHub, your own cron system, your own email address, and your own database? And what if your favorite AI assistant could build software with all of it on your behalf? That's Kody: a personal assistant platform where every user gets a fully isolated software ecosystem. Your AI writes packages into your own git repos, publishes them to your personal package registry with real versioned imports, schedules your jobs, runs your long-lived services and workflows, receives email at your own address, and stores everything in storage only you can touch. I built this entirely on Cloudflare, because Cloudflare is the only place it could be built. This is a technical deep dive into what happens when you take the newest parts of the developer platform to their limits: sandboxing AI-authored user code with Worker Loaders, per-user git hosting with Artifacts, modeling "one of everything per user" with namespaced Durable Objects, and composing D1, KV, R2, Vectorize, Queues, Workflows, and Email Routing into a true multi-tenant platform. If AI agents are going to build and run software for everyone, this is what the infrastructure underneath looks like. You can start building it today.
