A streaming game engine for the browser. It loads photoreal Gaussian-splat scenes — real-world captures, not modelled geometry — over the network, persists them to the local OPFS cache, and renders at 30 FPS on integrated GPUs. No download. The page is the whole product. See /how-it-works for the engine topology.
Prove that AAA-quality interactive experiences can be delivered to commodity browsers, including hardware that can't run a console title. Multiplayer, photoreal, open-world web games as a single engineering quarter rather than a decade away.
Brand assets stay © PAXAL. The source is under active development; a public-source release lands when the external surface stabilises. Until then see /credits for what we stand on and /community for contact.
Gaussian-splat rasters need compute pipelines for the point-projection + per-pixel blending work. WebGL2 can fake it but not at framerate. WebGPU is exposed by Chrome 113+, Edge 113+, Chrome on Android 12+, and Safari 18+ on macOS. The compatibility wall on the title screen lists every supported browser explicitly.
The first-run calibration picks a preset from your adapter string. If the heuristic picked too high a preset, open Settings (`,`) and drop to BALANCED or PERFORMANCE. The second visit will pin to that choice automatically.
Gamepad and touch yes (auto-detected; the mobile control overlay slides in on coarse pointers). VR is parked — splats render into a WebGPU canvas, not a stereo pair; the spike is a separate beat.
Yes. Every drivable arena is a Gaussian-splat capture — real photographs reconstructed as a point cloud with view-dependent appearance baked in. ROOM was self-captured; LUDLOW SQUARE and LA NIGHT are community-sourced under CC BY 4.0.
Yes. A fourth arena is on the LATER tier of /roadmap; it pushes the asset pipeline end-to-end with either a self-capture or a re-licensed open dataset.
The pipeline is scriptable — see scripts/pipeline.mjs and scripts/split-by-scale.mjs. Drop a .compressed.ply under public/arena/, add the entry to lib/arenas.ts, and run the dev server. Spawn-pose calibration is currently manual.
Splat chunks in OPFS (capped ~1 GB, LRU-evicted), a few KB of settings in localStorage (selected arena, audio mix, visual preset, calibration), a per-arena drive log, and the service-worker shell cache. Full breakdown at /privacy.
Anonymous PostHog telemetry: WebGPU adapter family, first-pixel time, FPS samples, cache hits and misses, arena selections. No account, no email, no IP-derived location. Opt-out lives at Settings → Privacy.
Settings → Network & Storage → CLEAR CACHE. Drops OPFS + service-worker shell. Preserves your preferences and drive log — those are separate concepts.
/changelog for one-line entries per shipping beat, /roadmap for what's next, /devlog for longer-form design notes.
pnpm invite "Their Name" generates a deep-link URL with an anonymous attribution token the runtime telemetry picks up automatically. URL goes to the clipboard. No data about the recipient leaves their browser.
