What is 绿色软件联盟?
绿色软件联盟 (Lvruan, also called 绿盟) is a green software download site that lists portable and free software for download, including many AI tools, alongside a growing set of online tools. The site says it has been running for about 20 years. Each software entry carries a short description, topic tags and an update date, covering categories such as office suites, developer IDEs, video downloaders, password managers and game engines.
Beyond downloads, Lvruan publishes online tools that run locally in the browser, such as a YAML-to-JSON converter, an XML formatter, a WebSocket tester, unit converters and a User Agent checker, so data does not need to be uploaded to a server. Visitors can browse by software, tools or tags, read the blog, switch language and theme, and optionally become a member to use credit-based downloads and publish, favorite or review software.
