Dev Facts Check answers short factual questions developers ask an agent: is this version still supported, what licence does this package use, which browsers support a feature.

What the picture leaves out

The picture shows the support-window question. Each answer gives the end-of-life date with its official source, so an agent can quote it instead of guessing.

Node.js majors are supported for about 3 years from release. On 11 October 2026, Node.js 20 has ended and 22, 24 and 26 are supported.
