A walkable ASCII cyberpunk city in one HTML file [video]
Points and comments are a snapshot, not live.
An ASCII cyberpunk city built as a walkable 3D environment in a single HTML file.
The video showcases a JavaScript/Canvas engine that renders a grid-based ASCII city with roads, buildings, trees, cars, and pedestrians. It uses raycasting for perspective, depth, and collisions, drawing everything with characters instead of 3D models or textures. The prototype is available for purchase on Ko-fi, and an update video shows interiors, larger scale, and elevated views. The project is still in development.
What commenters are saying
Many commenters praised the project as creative and impressive, with some calling it a standout internet find. Several noted that the live demo differs from the video, looking messier or harder to read, and that the video shows a newer, unreleased version. Some questioned the pay-to-play model for a basic prototype and noted the code is obfuscated WASM. A few discussed browser vs. terminal ASCII rendering, with some preferring terminals for SSH workflows.
