## What it is
Unplugin is a unified plugin system that lets developers write a single plugin compatible with Vite, Rollup, Webpack, esbuild, Rspack, Rsbuild, Rolldown, Farm, Bun, and frameworks built on them. It abstracts away bundler-specific plugin APIs so one codebase works across build tools.

## Use cases
- write a vite plugin that also works with webpack
- share one plugin across rollup and esbuild
- create bundler-agnostic build tool plugins
- port a webpack plugin to vite without rewriting
- support multiple bundlers with a single npm package
- build plugins for rspack and rolldown

## When to choose
- you maintain a plugin that must support several bundlers
- you want one codebase instead of per-bundler forks
- you build tooling for the Vite/Rollup/webpack ecosystem

## When to avoid
- you target only a single bundler and its native API suffices
- you need bundler-specific features not covered by the unified abstraction

## Facets
- artifact type: library
- maturity: stable
- function: build-tool, plugin-system, developer-tools
- domain: web-development, frontend, developer-tools
- platform: bun, cross-platform
- tags: vite, webpack, rollup, esbuild, rspack, rolldown, bundler-plugins, typescript, nodejs
