node.green is an ECMAScript compatibility query website for Node.js developers. The scraped content shows it revolves around "Node.js ES2015/ES6, ES2016 and ES2017 support", listing the support results of different language features in Node.js in a matrix format, and indicating that some capabilities may require the harmony flag. The page was created by William Kapke.
Its core value is helping developers determine whether a specific Node.js runtime supports a particular JavaScript feature. Visible test items include proper tail calls, default function parameters, rest parameters, etc., providing an executable JavaScript test function for each sub-item. Results are presented as Yes, Error, Flag, etc., intuitively distinguishing between native support, errors, or the need to enable experimental flags.
In terms of supported languages, node.green clearly focuses on Node.js and ECMAScript; it is not a general-purpose, multi-language development tool. It is more of a JavaScript runtime compatibility table rather than a build, debugging, CI, or IDE tool.
The content shows no paid plans, subscriptions, account systems, or commercial licensing info. It can be treated as a publicly free query site, though this does not confirm its complete business model. There is also no mention of APIs, SDKs, CLIs, browser extensions, or third-party integrations, making it primarily suited for manual queries rather than direct integration into automated pipelines.
Pros include high information density, straightforward conclusions, and test code attached to each compatibility check, making it ideal for rigorously evaluating the availability of a syntax feature. This kind of matrix is highly practical for teams maintaining legacy Node.js projects or preparing for runtime upgrades.
The cons are also apparent: the page is heavily tabular, and the scraped content lacks context for version columns, data sources, update frequency, and maintenance mechanisms. For beginners, statuses like Error and Flag require understanding in conjunction with the Node.js version and startup parameters. The content also shows no search, filter, or export capabilities.
It is suitable for Node.js backend engineers, JavaScript/TypeScript developers, and tech leads performing compatibility checks during tech selection or upgrades. Access from China cannot be determined solely from the text; cross-verification with MDN, official Node.js docs, Can I use, or kangax/compat-table is recommended.
