  • llrt

    LLRT (Low Latency Runtime) is an experimental, lightweight JavaScript runtime designed to address the growing demand for fast and efficient Serverless applications.

    https://github.com/awslabs/llrt/blob/e2cc8237f4bd04e161d46b3...

    This wraps QuickJS and there is not a single mention on their front page. At least a hello or shout-out to Fabrice Bellard would have been nice.

    But I guess it's AWS and they do this with other projects, so not too surprising.

  • winterjs

    LLRT is built using Rust, Tokio and QuickJS under the hood.

    We (at Wasmer), have been working on a very similar approach: WinterJS, which is using SpiderMonkey instead (but also built on top of Rust and Tokio). https://github.com/wasmer/winterjs

  • hermes

    A JavaScript engine optimized for running React Native.

    Hermes is a big one as well: low startup latency, low memory

  • pljs

    PLJS - Javascript Language Plugin for PostreSQL

    pljs (https://github.com/plv8/pljs) is a postgres language plugin that also uses quickjs. given how much faster the startup is compared to v8, and that most postgres functions are very small and do very little compared to a node.js program, it is quite good.

    I can definitely see aws' lambda operations gaining quite a bit from this.
