basicFusion is a retro game engine and coding playground that lives entirely in your browser. Type a line of BASIC, press run, and watch pixels move - no install, no setup, no waiting.
basicFusion is friendly enough for a first-ever program and deep enough for a finished game. Whoever you are, you start in the same place: a blank screen and one line of code.
Your very first program is one line long: PRINT "HI" and it's already on screen. Simple enough for a curious ten-year-old, honest enough to teach real logic.
Chase that 80s/90s demoscene feeling - raster bars, chiptunes, pixel sprites and raycasters - with every tool built right into the editor.
A whole classroom can code in the same browser tab. Nothing to install, nothing to break - share a link and everyone runs the same game.
Graphics, sound, levels and debugging don't need separate apps. basicFusion ships a full studio around the language.
Pixel-art editor with layers, undo and import/export.
Compose chiptunes note by note, right in the browser.
Zaps, jumps and explosions in a couple of clicks.
Paint levels that plug straight into your code.
Design your own pixel-perfect typefaces.
Build low-poly models for simple 3D scenes.
Walk your program line by line and watch every variable.
Hardware-free graphics and sound, straight from BASIC.
basicFusion speaks a clean, modern dialect of classic BASIC - the kind you can read out loud.
There's nothing to download and nothing to configure. Open the page and you're already coding. Loops, graphics, sound and input are single, memorable keywords, so you spend your time making things instead of fighting toolchains.
When your game is ready, export it and share it anywhere - the web, Windows, Linux or Android - from the exact same project.
