Everything You Need to
Ship Your Game

A complete game development environment — from visual editing to multi-platform builds.

GPU Rendering

WebGPU-powered renderer that adapts to Vulkan, Metal, or DirectX 12. Sprite batching and instancing, HDR pipeline, 2D lights with soft shadows, and a cinematic post-processing stack with 20+ effects.

Integrated Editor

An all-in-one scene editor with hierarchy, inspector, asset explorer, viewport tools, transform gizmos, snap settings, tilemap painting, sprite animation editor, and camera rig.

TypeScript Scripting

Write game logic in TypeScript with hot reload, full type checking, and IntelliSense in the embedded code editor. Type errors are caught before play mode even starts.

RedPrint Visual Scripting

A graph-based visual scripting system inspired by Unreal Blueprints. Create game logic by connecting nodes — no coding required. Compiles for production performance.

GPU VFX Graph

Node-based particle effects with context blocks — Spawn, Initialize, Update, Output, Collision, and GPU Events. A Slang-powered compiler turns your graph into GPU simulation code for massive particle counts.

Dual Physics Engines

Built-in engine or SIMD-accelerated deterministic engine. 6 collider types, gravity/buoyancy/wind zones, one-way platforms, raycasting, CCD, collision layers — with joints, motors, and soft bodies on the roadmap.

Built-in UI Engine

Declarative UI components with flexbox layout and CSS-like styling — transitions, keyframes, rounded clipping, acrylic blur, and shader materials on any element. Rendered natively by the engine.

MSDF Text Rendering

Crisp text at any zoom with multi-channel SDF glyphs. Variable font weights, kerning, ligatures, full Unicode including Cyrillic, SDF icons — and shader materials applied straight to glyphs.

Materials & Slang Shaders

Author shaders in Slang. Materials support variants, per-entity property overrides, and instancing — validated headlessly at build time and precompiled to SPIR-V for native builds.

Spatial Audio

Full-featured audio engine with spatial sound, HRTF panning, bus routing, mixer editor, per-source filters, and detailed inspector controls for every parameter.

Content Pipeline

Native Aseprite import, image format conversion, automatic thumbnails, drag-and-drop assets. Supports PNG, WebP, TGA, QOI, DDS, and more out of the box.

Multi-Platform Deploy

Build to HTML5, native Windows desktop (AOT-compiled with precompiled shaders), or Argon PlayFrame. macOS and Linux are coming next; mobile and consoles are on the roadmap.

Visual Editor

A Complete Game Studio
On Your Desktop

The integrated editor gives you everything — scene hierarchy, property inspector, asset explorer, viewport with transform gizmos, tilemap painting, play/pause/step controls, sprite animation editor, and a built-in performance profiler. All in one window.

Scene Hierarchy & Inspector Organize entities and edit components visually

Tilemap & Sprite Animation Paint tiles and create sprite animations in the viewport

Play Mode Play, pause, and step through your game within the editor

Camera Rig Cinematic camera sequences with target groups and blending

Code Editor with IntelliSense Write TypeScript with type checking and hot reload built in

Camera System

Cinematic Camera
Rig

A full camera orchestration system inspired by industry-standard tools. Priority blending between rigs, screen-space composition with dead & soft zones, spline dollies, orbital cameras, and procedural shake — all tunable in one inspector.

6 Position Modes Follow, Composer, Hard Lock, Spline Dolly, Orbital, or None

Screen Composer Dead zone + soft zone with offset. Target stays where you want it on screen

Camera Shake Procedural multi-frequency noise. Subtle, Handheld, Impact presets built in

Priority Blending Multiple rigs blend automatically by priority with configurable easing

Confine Bounds Soft or hard camera clamping to rectangular world bounds

Lookahead Camera anticipates target movement for buttery-smooth gameplay feel

UI Engine

Game UI That
Gotta Go Fast

A retained-mode UI built on the same GPU renderer as the rest of the engine — rounded-rect SDFs, MSDF text, gradients, 9-slice, acrylic backdrop blur and custom .slang UI materials, all batched. You style it with redcss: a genuine CSS engine — a real cascade, real specificity, real at-rules — not a lookalike property bag.

Real CSS, not a lookalike

redcss is the whole CSS front end — a real tokenizer, selectors, the cascade, 142 property mappers, calc() and @keyframes. One parser serves the editor and every shipped player, so a declaration cannot mean two different things depending on where it runs.

The cascade you already know

True (a,b,c,d) specificity, @layer, !important as a cascade layer, inherit / initial / unset / revert, custom properties resolved at their own cascade position, and CSS Nesting flattened at parse time.

Zero parsing at runtime

Stylesheets compile at import time and get baked into the shipped bundle. The player loads a resolved blob — it never tokenizes CSS to draw a frame. A syntax error is an authoring diagnostic with line and column, not a hitch.

Authored as Vue SFCs

.uix screens and .uic components with v-if / v-for / v-model / slots / <Teleport>. No DOM — templates use engine primitives, layout is flexbox, text comes from baked font atlases, and the whole tree batches down to a handful of draw calls.

Which CSS standard?

CSS has no version number any more — it is a set of independently levelled modules. These are the ones @engine/ui implements, in whole or in part:

css-syntax-3 selectors-4 css-cascade-5 css-variables-1 css-nesting-1 mediaqueries-5 css-conditional-3 css-flexbox-1 css-backgrounds-3 css-images-3 css-transforms-2 css-transitions-1 css-animations-1 css-text-3 css-fonts-4 css-logical-1 css-overflow-3 css-values-4 css-color-4 css-ui-4

No Grid, no floats, no tables, no pseudo-elements, no :has() — and each one is refused by name, with the blocker spelled out, instead of failing like a typo.

Measured, not claimed

The parser is graded against a pinned corpus of five stylesheets people actually ship — Bootstrap 5.3.3, Pico 2, Tailwind v4 preflight, Open Props 1.7.7 and modern-normalize.

FAQ

Frequently Asked
Questions

Is Red Pew Engine free?

Yes — completely free during Early Access (versions 0.x and 1.x) with no royalties. Starting from 2.x, we plan to introduce tiered pricing with a free Individual tier for studios earning under $300k/year.

Is it open source?

No. Red Pew Engine is closed-source proprietary software developed by Argon Inc. LLC. Source code access may be available under an Enterprise license in the future.

What platforms can I build for?

Today you can ship to HTML5 (any modern browser), native Windows desktop (AOT-compiled, no browser runtime), and Argon PlayFrame (embedded games). macOS and Linux desktop builds are coming in 1.x; mobile and console targets are planned for 2.x.

Do I need programming experience?

Not necessarily! RedPrint visual scripting lets you create game logic by connecting nodes — no coding required. When you want code, the engine uses TypeScript — with hot reload, full type checking, and IntelliSense in the built-in code editor.

What makes it different from Unity or Godot?

Red Pew is purpose-built for 2D from the ground up — not a 3D engine with a 2D mode. It features GPU-driven VFX, an HDR pipeline with 20+ cinematic post effects, 2D lighting with soft shadows, dual physics engines, a built-in UI engine with MSDF text, and spatial audio — all shipping as a single native app.

What rendering backend does it use?

The renderer is built on WebGPU and automatically targets Vulkan, DirectX 12, or Metal. Shaders are written in Slang and validated at build time; native Windows builds ship precompiled SPIR-V for fast startup, while web builds use WebGPU directly.

Does it work with AI coding tools?

The editor supports the Model Context Protocol (MCP), so MCP-capable assistants can be connected to it if you want — it's entirely optional.

How do I get it?

Red Pew Engine is distributed through Steam. Search for "Red Pew Engine" on Steam or click "Get on Steam" at the top of this page. It's free during Early Access.

Can I use it for commercial games?

Absolutely. There are no revenue limits or royalties during Early Access. Build and sell your games with full confidence.
