1ShotGen

Built with 1ShotGen

Each app below is real and running. Each was built by feeding one sentence to 1ShotGen, then pasting the single prompt it produced into a coding agent — no back-and-forth. Read the exact prompt, then go play with what it built.

Gravity3D — 3D n-body gravity sandbox screenshot

Gravity3D 3D · WebGL

“A 3D n-body gravity sandbox: glowing planets orbit in real 3D space; orbit the camera, fling new bodies, watch slingshots and merges.”

Real-time Newtonian n-body physics in WebGL — orbit and zoom the camera, drag-release to fling glowing planets that leave 3D trails, slingshot, and merge on collision in a starfield.

1 sentence → a 28,328-char one-shot prompt → this app, in one pass.

Cloth3D — interactive Verlet fabric screenshot

Cloth3D 3D · WebGL

“An interactive 3D cloth: a Verlet fabric you grab and drag, rippling under wind and gravity, with tearing.”

A draped Verlet-physics fabric in WebGL — grab and pull any point, tune wind, gravity, stiffness and tearing, switch pin modes, and orbit the lit, double-sided cloth.

1 sentence → a 30,235-char one-shot prompt → this app, in one pass.

Orbital — gravity sandbox screenshot

Orbital

“An n-body gravity sandbox: fling glowing planets and watch them orbit, slingshot, and merge.”

A Canvas-2D gravity sandbox under real Newtonian physics — drag to fling planets, add a sun, watch light-trailed orbits and momentum-conserving collisions.

1 sentence → a 23,678-char one-shot prompt → this app, in one pass.

Regex Lab screenshot

Regex Lab

“A live regex tester that highlights matches and explains each token in plain English.”

Type a pattern and sample text; matches highlight live, capture groups list per match, and a panel explains every token of the pattern in plain English. Eight examples included.

LifeCanvas — Game of Life screenshot

LifeCanvas

“A paintable Conway's Game of Life with patterns, speed control, and live stats.”

Paint live cells on a grid, play/step/randomize, tune speed and cell size, stamp classic patterns (glider, pulsar, glider gun), and watch generation and population update live.

1 sentence → a 28,435-char one-shot prompt → this app, in one pass.
