# Spiderbench — a browser web-swinging game written by Claude
A non-commercial fan project and benchmark. It shows the kind of code and assets that **Claude** (Anthropic's AI model, working through Claude Code) can produce for a real-time 3D game running in the browser.
The code, shaders, procedural city, Blender-built models and generated textures were produced by Claude under the direction of a human, who steered the work through feedback and reference images.
## What's in it
- **Traversal:** third-person web-swinging, wall-running, perching, zipping and diving, driven by a custom physics and animation state machine.
- **City:** a procedural Manhattan-style island with an authored street network, including Broadway, Greenwich Village and the Financial District. It has thousands of buildings, rooftops, parks, Times Square, bridges, traffic and pedestrians.
- **Rendering:** a Three.js (WebGL2) pipeline with cascaded shadows, screen-space GI, AO and reflections, bloom, TAA, motion blur, fixed time-of-day presets (including night and rain), and a day/night city.
- **Assets:** character, vehicle and pedestrian models and animation clips built by Blender Python scripts, plus AI-generated textures and ad art. Advertised brands are invented, apart from in-universe Marvel names such as the Daily Bugle and Oscorp.
## Run it
Requires Node.js 20.19+ or 22.12+ and a WebGL2-capable browser. A discrete GPU is recommended.

Controls are listed in-game (press **H**). On the dev server, **~** opens a developer menu (on a build, add `?dev` to the URL).
