QuickJS-NG is “a fork of the original #QuickJS project by Fabrice Bellard and Charlie Gordon, after it went dormant, with the intent of reigniting its development.” That's great: I wouldn't want to be caught with an unsupported runtime.

I'm very glad I looked through the project's issue list, though.

https://github.com/quickjs-ng/quickjs/issues/1172 describes that in a benchmark, -NG is 10% slower than the original. Unfortunate, but it's understandable that -NG could have become bloated over time with all the extra coding.

The truth surprised me: the original is still being updated and has performance optimisations that -NG haven't incorporated yet! So not quite dormant, then!

In the v8v7 test, qjs-ng's performance lags behind qjs · Issue #1172 · quickjs-ng/quickjs

#txiki.js is my tiny JavaScript engine built on top of #QuickJS. I just released version 26.3.0, the biggest release since I started the project: HTTP and WebSocket server, fully static builds on Windows, and more! Check out the blog post: https://code.saghul.net/2026/03/txiki-js-26-3-0-released-a-new-dawn/ and full release notes: https://github.com/saghul/txiki.js/releases/tag/v26.3.0

"Security researcher Sean Heelan recently tested two sophisticated systems built on GPT-5.2 and Opus 4.5, challenging them to develop exploits for a #zeroday flaw in the #QuickJS Javascript interpreter.

The results point to a significant shift in offensive cybersecurity capabilities, where automated systems can generate functional attack code without human intervention."
