Made for the devices you keep.

What we build

Our work includes PSP apps and Android launchers, with PS Vita and other platforms on the roadmap. PSP Tube is our current PSP project. KZE OS is a planned project exploring a social hub, themes and modern apps; it is not a released operating system.

Each project page shows its published builds, supported devices, access requirements and release notes. A planned feature is a direction for development, not a promise of delivery.

Free releases and memberships

Some releases are free. Patreon memberships support KZE development and unlock the releases included in a member’s tier. Supporter covers stable member releases; Insider adds beta, development and experimental builds. Core YouTube playback in PSP Tube remains free.

KZE membership provides KZE-developed benefits. It is separate from YouTube Premium and does not grant rights to third-party videos or services.

Useful feedback, honest compatibility

Our device feedback records the app version, edition, build and model reported by each reviewer. These reports help us identify patterns across devices. A successful report on one PSP is useful evidence, but does not guarantee the same result on every firmware or setup.

Release notes and installation help are published alongside the downloads. Please include your model, version and the steps that led to an issue when asking for support.

Independent and unaffiliated
