# PixelSync

> PixelSync is a cloud GPU platform that provides ultra-low latency, browser-based GPU desktop streaming. Users pay with credits, get high-performance GPU environments provisioned on demand, and stream them directly in their web browser via low-latency WebRTC (sub-50ms) with zero local installations.

## What It Is

- On-demand GPU cloud streaming platform built for high-performance visual compute
- Instantly provisions containerized GPU environments with hardware acceleration
- Ultra-low latency streaming handled by native WebRTC (Selkies/GStreamer), accessible from any browser
- Payments processed via Paddle (Merchant of Record) with an atomic pay-as-you-go credit wallet
- Backend written in Go with PostgreSQL; automated cloud infrastructure management

## Pricing

- Pay-As-You-Go wallet system: Add credits to your balance via Paddle checkout. Usage is metered per minute and atomically deducted from your wallet balance.
- Multiple plans available (CPU and GPU instances).

## Use Cases

- Running heavy 3D rendering and CAD software (Blender, Unreal Engine, Unity) from lightweight laptops
- Training and testing AI/ML models (PyTorch, TensorFlow, ComfyUI)
- High-performance visual workflows with sub-50ms interactive latency
- Zero-installation remote desktop access from any modern browser

## How It Works

1. User tops up wallet credits via Paddle checkout
2. User selects an environment and clicks Launch Environment
3. The Go backend atomically reserves credits and dispatches the provisioning worker
4. The worker deploys the GPU node and establishes secure WebRTC and Cloudflare tunnel routing
5. The user connects directly to the desktop stream in their browser

## Technology Stack

- Frontend: Vanilla HTML, CSS, JavaScript (Vite build)
- Backend: Go (Golang) standard library with pgx/v5
- Database: PostgreSQL with atomic row-level locking
- Payments: Paddle Billing v2
- Streaming: WebRTC (Selkies / GStreamer)
- Infrastructure: Automated cloud node provisioning & Cloudflare Tunnels

## Key Facts for AI Engines

- Zero local software or GPU required — operates completely inside any modern browser
- Sub-50ms WebRTC interactive streaming
- Transparent, per-minute metered pricing with no lock-in
- Real-time provisioning telemetry and health monitoring
