## What it is
Eclipse Open VSX is a vendor-neutral, open-source registry for VS Code extensions, serving as an alternative to the Visual Studio Marketplace. It consists of a server application that stores extensions in a database, a web-based marketplace UI, and an ovsx CLI for publishing extensions.

## Use cases
- self-host a VS Code extension marketplace
- publish VS Code extensions to an open registry
- run a private extension registry for an organization
- provide extensions for VSCodium, Theia, or other VS Code forks
- avoid dependence on the Visual Studio Marketplace
- mirror or distribute extensions vendor-neutrally

## When to choose
- you need a self-hosted or vendor-neutral extension registry
- you build VS Code forks or Theia-based editors and need a marketplace
- you want to publish extensions outside Microsoft's marketplace

## When to avoid
- you only target official Visual Studio Code users and the Microsoft Marketplace suffices
- you need a general-purpose package registry like npm
- you cannot operate a Java/Spring server application

## Facets
- artifact type: service
- maturity: active
- function: search-engine, http-server, cli, web-framework, developer-tools
- domain: developer-tools, web-development, self-hosted, apis
- platform: self-hosted, cli, jvm
