About Phluxel

Paint pixels. Write a rule. Watch it come alive.

Add living effects — rain, fire, snow, glow — to your pixel art in

minutes, no frame-by-frame. Paint a grid, write one tiny Phlux rule, and

export seamless GIF, MP4, or APNG loops.

A rule answers one question

Phlux is a tiny, readable rule language: describe how a cell becomes its

next self from its neighbors, and Phluxel runs it on every pixel in real

time.

[code]R = (N.R + S.R + E.R + W.R) / 4 // diffuse[/code]

One line like that is a fire, a rain shower, a Game-of-Life variant, or a

slow generative bloom — no shader code, no timeline scrubbing frame by

frame.

Everything in one window

•
The Phlux rule language — channels, math, conditions and scatter, readable in one line, with a cheat sheet, autocomplete and a live preview in the Monaco-powered editor.
•
GPU + CPU engine — global rules compile to GPU shaders and ping-pong render textures for real-time playback, with toroidal wrapping. Per-cell logic falls back to a precise CPU interpreter automatically.
•
No canvas size limit — work at 128x128 or 4000x3000. Editing stays responsive at either end, and undo scales itself to your canvas so memory stays bounded.
•
Import anything — drop in PNG, JPG, BMP, animated GIF or WebP as a starting state and let a rule remix it.
•
Export seamless loops — one-click GIF with ping-pong for perfect back-and-forth loops, plus PNG sequence, APNG, MP4 and sprite sheets. Lock any export to a fixed palette — including Lospec .hex, GIMP .gpl and .pal files.
•
Timeline & keyframes — animate rule parameters over time. Scrub, keyframe, and choreograph evolving simulations.
•
Starters & templates — 62 one-click live starters and a library of 65 rule templates to remix. Go from blank to animating in a click.
•
Snapshots & undo — capture multiple snapshots of a field and step back through deep, non-destructive undo history.
•
Native & fast on Windows — built on .NET 10 with a native Raylib + Dear ImGui front end — docking panels, custom themes, and a fully rebindable keymap.

Four steps to your first animation

No coding needed to start — pick a starter, or build one from scratch.

You can have a shareable GIF in about five minutes.

•
Paint a state — brush, fill, shapes and an eyedropper on a pixel grid. Or import an image; a few dots is enough.
•
Write a rule — one line of Phlux says what each cell becomes from its neighbors. Toggle Global to run it everywhere.
•
Press play — watch it evolve in real time. Step frame by frame, tweak speed, and reset to your design anytime.
•
Export & share — save a seamless ping-pong GIF, an MP4, an APNG, or a full PNG sequence. The result is the ad.

Pay once. Own it forever.

No subscription, no account, no cloud lock-in. One purchase unlocks

everything, on your machine, offline — and it keeps working whether or

not you keep paying.

•
No watermark on anything you export.
•
Unlimited grid size, resolution and frame count.
•
Every export format — GIF, MP4, APNG, PNG sequence, sprite sheets.
•
Commercial use: sell what you make.

Under the hood that's a full rule-scripting language, a dual CPU/GPU

simulation engine, and a keyframe timeline — not just a slider-based

effects generator. You don't pick an effect from a list; you write it,

and then you can change it.

Do I need to know how to code?

Not to start. The Starter Gallery and 65 rule templates get you

animating with a single click. When you're curious, Phlux rules are

usually one short, readable line — and the editor has a cheat sheet,

autocomplete and inline hints.
