🎉 JBang just passed 3 MILLION binary downloads! A 2019 experiment to make Java easier to run — `jbang hello.java` — has quietly become Java infrastructure. ~1,000 downloads/day, 130+ countries, Java 8 → Java . Thank you 🙏 https://www.jbang.dev/learn/somehow-jbang-just-passed-3-million-downloads

LLMs just can't stop writing java.util.Map<String, java.util.List<String>> instead of using imports 😅 Made a PR for Spotless to auto-fix this: shortenFullyQualifiedTypes() 🤞 for a speedy merge! https://github.com/diffplug/spotless/pull/3005

So close…

jbang app install jfr-mcp@btraceio Now just tell your agent to add jfr-mcp —stdio as mcp server and you have awesome portable Java performance help. Awesomeness.

Almost at 3 million downloads of JBang! 🎉 Screenshot the counter when it hits it in the next week! Thank you to everyone who uses, contributes to, and shares JBang. You make this happen. www.jbang.dev/usage/downlo...

Does anyone in my network work on or with JFrog Artifactory? We've been hitting bugs that have been open for *years* and appear completely stale. I refuse to believe nobody's looking at these. Would love to talk to someone on the inside before I lose my mind. 😅

Wrote about the migration to Aesh in JBang at https://www.jbang.dev/learn/from-picocli-to-sh-how-porting-jbang-s-cli-made-everything-better/ Yet again we see what impact reflection vs build time processing can have on even the small things!

jhostty running various tamboui demos

#TamboUI - the first modern Java TUI library. It promises support ranging from low-level terminal drawing to high-level APIs, including components and event handling. Now at v0.3.0, it’s already being adopted by major projects like Maven & Spring. 🔗 Learn more: bit.ly/4fKgoSL #InfoQ #Java

Nice InfoQ article about TamboUI https://www.infoq.com/news/2026/05/tamboui-java-tui/

TamboUI Promises to Bring Better Capabilities to Build TUIs in Java

The call to action “to make 2026 the year of Java in the terminal” was quickly responded to by the launch of TamboUI. Inspired by Ratatui, the library used in Claude CLI, it promises support ranging from low-level terminal drawing to high-level APIs such as components and event handling. Currently at version 0.3.0, it has already been adopted by major projects such as Maven and Spring.

The recent fixes @staalep.bsky.social been making to get aesh to match picocli features been really fun to do.

Max Rydahl Andersen@maxandersen.xam.dk · 2mo ago

Working on picocli to aesh migration the last few weeks for JBang. The startup difference is amazing: 2-17x faster. JVM mode is now amazing but native mode is even faster. lesson learned again and again - reflection is a startup killer; build-time makes all the difference!
