## What it is
Vello is a GPU compute-centric 2D vector graphics rendering engine written in Rust, built on wgpu. It renders large 2D scenes (shapes, gradients, text, images) with interactive performance and serves as the rendering backend for the Xilem GUI toolkit.

## Use cases
- render 2D vector graphics with GPU acceleration in Rust
- build a custom GUI toolkit rendering backend
- render SVG-style scenes and canvas drawings at high performance
- draw large 2D scenes with interactive frame rates
- render text, gradients, and shapes in a Rust application
- run 2D rendering in the browser via WebGPU

## When to choose
- you need high-performance 2D rendering in Rust that leverages GPU compute
- you're building a Rust GUI app or toolkit and want a modern rendering backend
- you want WebGPU-based rendering that works cross-platform and in the browser
- you're comfortable with an alpha-stage library and want to follow the Linebender ecosystem

## When to avoid
- you need mature, production-stable rendering with full feature support like blur and filters
- you need a battle-tested renderer comparable to Skia or Cairo today
- your project depends on glyph caching and polished GPU memory management
- you're not using Rust or a wgpu-compatible environment

## Facets
- artifact type: library
- maturity: experimental
- function: graphics, image-processing
- domain: graphics, web-development, developer-tools
- platform: rust, cross-platform, wasm
- tags: 2d-renderer, vector-graphics, gpu-compute, wgpu, rendering-engine, gui-toolkit-backend, gpu
