Zero
Cross-platform voxel sandbox: build, dig, play together
Zero is a multiplayer voxel sandbox you play in your browser, on iPhone, on macOS, or on Windows (Mac and Windows are in desktop beta). One Rust engine across all four platforms, so building on iPhone produces the same world your friend sees in Chrome, byte-for-byte. Most voxel sandboxes are cubic-only (Minecraft, Hytopia) or smooth-only (Avoyd). Zero supports both: cubic brushes ship today, smooth-curve sphere brush in active development.

Hi Product Hunt! Doeon here, one of the 2 people behind Zero. A bit of context: I'd never built a game before. Last year I posted Ask HN looking for game-dev resources (https://news.ycombinator.com/ite...), and 140+ developers wrote back. A lot of what we shipped traces back to that thread. Six months ago we started. Today Zero runs in four places: browser (https://0.space), iPhone, and a very early desktop beta on macOS and Windows. One Rust voxel engine across all four, same world byte-for-byte on every device. We just finished the C++ to Rust migration. Heads-up on desktop: it's a very early beta. Expect bugs. If you try the macOS or Windows build and hit something (crash, install, sync, anything), please drop a comment here. Bug reports from this stage really help. Today: cubic brushes (Minecraft-style block stacking), real-time multiplayer, instant join. Coming soon: a smooth-curve sphere brush that uses dual-contouring under the hood. One thing to be upfront about: core game mechanics are intentionally thin right now. The first 6 months went into validating the technical foundation. The mechanics layer (gameplay loops, progression, deeper in-world systems) is what we're building next. Two of us. Still early. Would love to hear what you think :)
