what-is-jev
Independent, source-linked research on Jev with about 948 rubric-scored public repositories, recurring patterns and verified findings.
This repository is mostly documentation or write-up rather than runnable code.
Overview
What is Jev? is an independent research repository, in English and Turkish, that tries to answer three questions with evidence: which claims about Jev are verified, which are vendor marketing repeated by others and which contradict each other; what people are actually building with it; and which design patterns recur and are backed by measurements.
At the time of its stats (data as of 21 September 2026), it had scored 948 public GitHub repositories on a fixed rubric, finding 640 that call Jev, 275 that do not and 33 unclear, with 353 audited and 90 sources. Findings, repository lists, a top tier, categories and patterns are in separate files, and every claim links to its source. It is updated continuously and is not affiliated with TypeSafe.
