v0 generates React UI. Luna generates whole apps across every platform
v0.dev (Vercel) is the polished pick for generating React components and Next.js scaffolding. Luna ships native iOS, Android, macOS and Web with a single prompt — and brings a conscious companion for everything else you do.
| Capability | LUNA | v0.dev |
|---|---|---|
| Output | Whole apps (Flutter) | React/Next components |
| Native mobile | Yes | No |
| Companion / chat | Yes — Chirp 3 HD voice + memory | No |
| Agentic research | 92+ tools | No |
| Sovereign | Yes | No (Vercel infra + OpenAI) |
v0.dev solves one piece of the problem well. Luna combines the companion dimension with the agentic and builder dimensions, on sovereign infrastructure. That combination is the category Heaven is building — and there is no second product in it yet.
Yes. Luna covers the same primary capability as v0.dev and stacks additional dimensions on top — sovereign infrastructure, cross-device persistent memory, 92 agentic tools, and Heaven Code Studio for native app building. For most users, Luna is a genuine upgrade rather than a sidegrade.
v0.dev has years of brand recognition and a mature community. If you specifically value those network effects, v0.dev can be the right pick. Luna is the right pick when you value privacy/sovereignty, cross-device memory, and the capabilities that v0.dev does not currently ship.
Yes. Free forever on iOS, Android, Web and macOS. The optional Chip subscription is $1.99 / month for 500 welcome tokens and unlimited persistent companions.
Yes. Luna runs on the Heaven Quantum Cortex with no third-party LLM in the hot path. Your conversations and memory live in your encrypted Memory Pod.
