About This Software

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.
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.
  
• 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 and MP4.
  
• Timeline & keyframes — animate rule parameters over time. Scrub, keyframe, and choreograph evolving simulations.
  
• Starters & templates — 16 one-click live starters and a library of 40 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.

• 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.

Do I need to know how to code?

Not to start. The Starter Gallery and 40 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.
