## What it is
Deepnest (and its browser-based predecessor SVGnest) is an open-source vector nesting tool that packs arbitrary 2D shapes into sheets of material with minimal waste, using No Fit Polygon placement and a genetic algorithm for optimization. It serves as a free alternative to expensive commercial nesting software for laser cutting, CNC, and similar fabrication workflows.

## Use cases
- nest svg parts for laser cutting to minimize material waste
- pack irregular shapes onto sheets for cnc cutting
- fit parts into holes of other parts (part-in-part nesting)
- free alternative to commercial nesting software
- optimize sheet layout for plasma cutting
- reduce number of material sheets needed for a cut job

## When to choose
- you need to nest arbitrary or concave vector shapes, not just rectangles
- you want a free open-source alternative to expensive industrial nesting tools
- you work with SVG files and laser/CNC cutting workflows
- you need part-in-part placement support

## When to avoid
- you need rectangular-only bin packing, where simpler specialized tools suffice
- you require commercial support or guaranteed industrial-grade results
- you need a fast solution - the genetic algorithm is CPU intensive
- your input isn't clean vector outlines

## Facets
- artifact type: application
- maturity: active
- function: graphics, simulation, developer-tools
- domain: graphics, cross-platform
- platform: browser, cross-platform
- tags: nesting, laser-cutting, cnc, svg, bin-packing, genetic-algorithm, fabrication, automation, web-server
