Your builds. Clear boundaries.
Moss & Blocks is an independent early-access blueprint tool operated by Drew Bayles. Browse the original public designs freely; your saved library is private to your account.
An independent project
Not an official Minecraft product. Not approved by or associated with Mojang or Microsoft. Minecraft describes compatibility. Previews use original geometry and simple colors, without game textures or official logos.
Your account and library
Amazon Cognito manages email sign-in and account recovery. AWS stores your account details, saved blueprint files, titles, descriptions, tags and generation status. The app uses your account ID to authorize access to your library. Session tokens are stored in your browser’s session storage; closing the tab or signing out ends the local session.
Removing a blueprint hides it from your library. Stored records and previous revisions remain available to the operator for recovery. Download a JSON copy before removing a build. Contact the operator to request permanent removal of your account or stored builds. Operational logs are retained for seven days; temporary generation and daily-usage records expire after seven days.
Templates and generation
Template creation runs without an AI provider. No build prompts are sent to an AI service in this release. Templates select from four original design families; describing an idea does not generate arbitrary new geometry. Inspect the layers before building in your world.
Advertising and local storage
Advertising is currently disabled. The site contains reserved placements for a future AdSense integration. Before advertising is enabled, this policy will be updated and the site will provide the required consent controls. No advertising script loads in the current configuration. The app uses browser session storage for sign-in and pending generation status.
Original work and respectful use
Use these original designs as building references in your worlds. Upload only blueprints you have the right to use. Do not upload someone else’s paid plans without permission. User uploads are private; community publishing, third-party sales and payments are not available.
Early release limits
The supported block set targets Minecraft Java 1.21.1 and 1.21.4, with up to 32 blocks per axis and 12,000 placed blocks. Creation is limited to 20 templates per account per UTC day; a library holds 100 active blueprints. JSON exports use the Moss & Blocks blueprint format and are not directly importable into Minecraft.
