Looking for maintainer for jvm-brotli
If you've read this far, you might be interested to know that Javalin has been offering Brotli compression through jvm-brotli for three years already, and that there have been no (reported) issues. In other words, the effort required to release and maintain this is probably not huge.

Question about Kotlin from an ex-Java developer
I'm a big fan of Ktor (ktor.io) but another reasonable lightweight alternative is Javelin (https://javalin.io/). Heck even Spring Boot isn't that bad. HikariCP + JooQ (has both java and kotlin codegen) for DB access if you need and you're good to go.

Turbo: The speed of a SPA without writing JavaScript
A similar alternative that does not rely on web sockets is https://htmx.org. I have greatly enjoyed using it with some simpler web frameworks like https://javalin.io to do some prototyping and smaller projects. I'm sure if someone made a plug and play UI library like material UI for Angular on top of htmx you could absolutely fly through MVPs.

Java Servlets
If you're already familiar with most of the concepts around HTTP and web services, I'd recommend using something like https://javalin.io/ which is light weight frame work that makes getting something up and running quickly a very easy task.

Why people don't love Java?
I've been looking at https://javalin.io/ Seems close enough to express and some big names are using it, so I wouldn't say it's fizzling out

Is there Expressjs like framework for java
Javalin (https://javalin.io) is strongly inspired by Express and Koa, so you should feel right at home:

There is no magic in Spring, I wrote my own (very simplified) framework from scratch to show it
If you want to do a proper comparison between the two, I would be happy to help with code examples from Javalin's side. I could even host it on https://javalin.io as a "Comparison to Jooby" blog post.

Spark – A web micro framework for Java and Kotlin
https://vertx.io/
It's actively maintained with full time developers, performant, supports Kotlin out of the box, and has more features?

Reactive database access on the JVM
Hibernate Reactive integrates with Vert.x, but an extension allows to bridge to Project Reactor if wanted

Have you looked at Vert.x?

What's the state of server-side frameworks with Kotlin support today for small teams?
Explicitly so:

Anything close beam/otp for other languages?
I really like Eclipse Vert.x... As both an Erlang dev and Java dev, it's a great synergy and soon to have support for Virtual Threads similar to BEAM.

Go doesn’t do any magical stuff and I love that
There are many lean, popular, non-magical libraries in Java land. (https://quarkus.io/, https://vertx.io/, etc). Spring is a monster 😱. Its like comparing Kubernetes (written in Go) with some lean framework in another lang.
