Interesting comparison from the @quarkus.io maintainers shows that @graalvm.org native image remains by far the best option to deploy Quarkus applications for optimizing startup time, container image size, and memory consumption (RSS). Link in comments.
Learn how Picnic built a rule engine on GraalVM, where rules are defined in JavaScript or Python and executed by a Java backend, handling 37M evaluations and 2M actions daily 🚀

Do you actually need JIT, or are you paying for unpredictability?
@thomaswue.dev (Founder of GraalVM) explains when JIT makes sense, when it doesn’t, and why predictable performance matters more than peak numbers.

Had an extensive conversation with Marco at @jetbrains.com about the future of @graalvm.org, the benefits of ahead-of-time compilation, and whether AI is going to take over compiler development 😉.
WasmGC is coming to GraalWasm, unlocking the power of JVM garbage collectors for #WebAssembly! This will also get GraalWasm a lot closer to implementing the full Wasm 3.0 spec.

Trying out the upcoming Spring Boot 4 + @graalvm.org 👀
A complete Spring Boot web service:
— compiles to native in 33.8s (quick build mode) ⚡️
— starts in 0.034s 🎉
🚀🚀🚀
People that complain GraalVM native builds are slow still live in the stone age 😅
Obviously native builds will remain slower, but the improvements the Graal team made the past years on the compiler (and resource usage!) are seriously impressive 👍
Native images are getting (experimental) support for dynamic class loading, see github.com/oracle/graal....
The @kotlinlang.org team at @jetbrains.com is working on a @graalvm.org-compiled kotlinc. Early experiments look very promising:
> So far, a native image with PGO offers a properly "warmed-up" kotlinc and with up to 20% more peak throughput.

Continued Focus on Native by Severin Gehwolf
Quarkus continues to focus on native for swift start-up time and low memory footprint. Learn more in By Severin Gehwolf's blog post, "Continued Focus on Native"

Really great to see plans for adding better integrated support for running @graalvm.org language implementations for JavaScript, Python, and WebAssembly in your Spring applications! github.com/spring-proje...
Very happy to see participants from so many different companies at the @graalvm.org Community Summit 2025!

Recording of my talk at @devoxx.com 2025 with @starbuxman.joshlong.com is now online! Watch for 50 minutes live (pair)coding entertainment showing GraalVM performance 🚀 for Spring apps, how you can mix in Python 🐍, and some more crazy demos 👀. Let me know your comments! m.youtube.com/watch?v=YlMi...
Memory efficiency of @graalvm.org Native Image: a Spring Boot application serving 100000 requests with high peak performance using only 80 MB of RAM 🚀
By @starbuxman.joshlong.com and @thomaswue.dev at @devoxx.com
Had a blast delivering together with @starbuxman.joshlong.com our Bootiful GraalVM talk at #Devoxx!
✨10✨ @graalvm.org talks are waiting for you at @devoxx.com this year!🚀
We'll cover a wide range of topics — from WebAssembly and Native Image to GPU acceleration and robotics!
Let's take a closer look 👀
Josh @starbuxman.joshlong.com and @thomaswue.dev will look at some of the amazing ways that Spring and GraalVM are a great win for your JVM applications in 2025. Blazingly fast startup, better security, and lower footprint for greener and cheaper production deployments!

#GraalVM 25 is out! 🚀
Exciting updates for #GraalPy, #GraalJS, and #GraalWasm — plus our first preview of #WebAssembly compilation!
Quoting from our license FAQ at www.graalvm.org/faq/: “the GFTC is intended to permit use by any user including commercial and production use. Redistribution is permitted as long as it is not for a fee.”
The GraalVM open source project was founded to make programmers more productive and programs more efficient for as many languages as possible. While the focus on programming languages may shift over time, the GraalVM project including its current vibrant community will continue on.
GraalVM 25 is here, with many new features and improvements. We'll talk more about our favorites in the next few days. Stay tuned 💪
Happy to see GraalVM 25 is out 🎉
