Overview

Vifu builds open-source infrastructure for AI-native games. The Agent Runtime provides the execution layer. VifuHub presents playable releases and, when the owner opts in, the latest workspace source as public projects.

A VifuHub project

VifuHub is project-centered. A public project can present:

Project
├── Playable app
├── Current reviewed release
├── Optional latest workspace source
├── License
├── Creator attribution
├── Runtime metadata
└── Optional upstream repository

The current MVP versions the reviewed runtime release and workspace source independently. The Files tab is explicitly the latest owner-published workspace and may be newer than the runtime visitors play. VifuHub does not present source updates or owner upload history as release history; it exposes only the current reviewed release until immutable public release records exist.

An upstream link may identify the original development location. It is project metadata, not evidence that the linked repository exactly matches the current runtime release.

Curated projects distinguish the Original creator, Upstream source, Packaged or maintained by Vifu, License, and VifuHub release. This does not imply that an original creator has registered with or maintains the VifuHub project.

Source status

Status	Meaning
Open Source	Source is public and includes a clear open-source license.
Source Available	Source can be viewed, but use, modification, or redistribution is restricted or unclear.
Playable Only	The playable release is available without owner-published public source.

VifuHub prioritizes Open Source projects. Do not label a project Open Source only because a build or source archive can be downloaded.

Developer building blocks

Part	Purpose
Agent Runtime	Runs agents, state, resources, capabilities, and playable game code.
Project format	Describes the build, runtime entry, resources, and release metadata.
VifuHub SDK	Connects game code to Agent Runtime services and declared host capabilities.
VifuHub CLI	Builds, checks, and publishes playable releases with vf.
VifuHub	Presents the game, optional latest workspace source, current reviewed release, license, attribution, runtime metadata, and upstream link.

The Agent Runtime explains how an AI-native game runs. VifuHub explains how that game exists as a public project. Real projects make runtime requirements visible; the runtime gives those projects a consistent, reproducible structure.
