Vibe App SDK

Build an app or game that runs inside EveVolved — two ways. Tell an AI agent what to make (the eve_ path), or write the eve.* JavaScript yourself (the mk_ path). Every capability is documented once and shown in either mode — flip the toggle.

The Vision

Why EveVolved exists — and what you are really building when you ship an app into it.

A world, not a feed

EveVolved is a living, walkable 3D social world— Vibe Nation — built on real-world geography. It is not a feed you post into and scroll past. It is a place you are in: you walk it, you run into people, you hang out, play, make things, and trade — together, in real time, in one shared space. It runs in the browser, it is VR-ready, and it is one continuous world.

Most platforms hand you a box to pour content into. EveVolved hands you ground to build on. That difference is the entire reason this SDK exists.

Your code runs inside the world

When you ship a Vibe app it does not sit in a walled-off store waiting to be downloaded — it drops natively into the world. Your game becomes a place people walk into. Your object becomes something they pick up and hand to a friend. Your tool becomes something they pull up mid-conversation.

The Vibe app is the atomof EveVolved — apps, games, objects, avatar pieces, whole spaces are all built the same way, by people like you. You are not building for a platform. You are building the world itself. (Start at Getting Started.)

You get paid, directly

The economy is non-custodial Lightning. When someone pays for what you made, the value splits straight to the walletsof everyone who built it — no platform sitting in the middle holding your money. Make something people want, and you earn from it directly.

Charging is a single call — eve.pay.request— and the host runs the whole flow, splits the value per your manifest, and grants the entitlement your app checks. You never touch a key, a card, or a balance. (See Economy & Monetization.)

Two ways in — describe it, or write it

You do not have to be a graphics engineer to build here. There are two paths to the same world and the same capabilities.

Describe it to an AI (the eve_path) — tell an agent what you want and it wires the eve.* calls for you. Or write it yourself (the mk_ path) — plain HTML / JavaScript against window.eve, no build step, no dependencies. Every capability in these docs is shown both ways— flip the toggle at the top.

That is the vision: a world anyone can add to, that pays the people who build it. Everything that follows is what you need to add your piece. (Next: Getting Started.)
