Chicory: A JVM native WebAssembly runtime

1. Graal

   1 172 20,800 10.0 Java

   GraalVM compiles Java applications into native executables that start instantly, scale fast, and use fewer compute resources 🚀

   

   How does it compare to graal wasm? https://github.com/oracle/graal/blob/master/wasm/README.md/

2. InfluxDB

   influxdata.com featured

   InfluxDB high-performance time series database. Collect, organize, and act on massive volumes of high-resolution data to power real-time intelligent systems.

   

3. upstream__bazel

   2 1 0 0.0

   Local branches of https://github.com/bazelbuild/bazel

   

   Chicory seems like it'll be pretty useful. Java doesn't have easy access to the platform-specific security mechanisms (seccomp, etc) that are used by native tools to sandbox their plugins, so it's nice to have WebAssembly's well-designed security model in a pure-JVM library.

   I've used it to experiment with using WebAssembly to extend the Bazel build system (which is written in Java). Currently there are several Bazel rulesets that need platform-specific helper binaries for things like parsing lock files or Cargo configs, and that's exactly the kind of logic that could happily move into a WebAssembly blob.

5. wasm-bench

   4 1 2 6.8 Rust

   

   I think there are still some gaps but we are comparing results(with GraalWasm) on Photon here: https://github.com/shaunsmith/wasm-bench

6. opa-java-wasm

   5 1 14 9.0 Java

   OPA Wasm rules using Chicory as the runtime (experimental)

   

   A few cool things based on Chicory:

   OPA: https://github.com/StyraInc/opa-java-wasm

   Integration with Debezium has been launched today too: https://debezium.io/blog/2025/02/24/go-smt/

   And SQLite will come next: https://github.com/roastedroot/sqlite4j

7. sqlite4j

10. Bytecoder

    8 5 920 7.3 Java

    Framework to interpret and transpile JVM bytecode to JavaScript, OpenCL or WebAssembly.

    

    also https://github.com/mirkosertic/Bytecoder and https://github.com/i-net-software/JWebAssembly as well as the already mentioned (in some other comment) https://cheerpj.com/

    most of them are still experimental, while CheerpJ offers Enterprise support (but it targets the browser).

    oh, and let's not forget j2cl https://github.com/google/j2cl
