Apple releases Pkl – onfiguration as code language
My employer uses a combination of Protocol Buffers (for the config schema definition) and Bazel/Starlark (for concrete instantiations). Configs are validated at build time and runtime using CEL (https://github.com/google/cel-spec).

Pure Ruby implementation of Google Common Expression Language
Looks like Google invented a specification for a simple "expression language." -> https://github.com/google/cel-spec/blob/master/doc/langdef.md. Writing the expressions feels like writing Java, C++, Go, or TypeScript code. Google then released C++ and Go versions of this langauge as a library.

A library for evaluating expressions like Google Common Expression Language but for Java
https://github.com/google/cel-spec unfortunately, it's in Go or C++. Of course I can write a binding to them. But is there any other similar that you would know of for Java? My other course of action would be to offload computation to another service using this library in Go, or Jsonnet or Open Policy Agent/Rego based evaluation, which I'd prefer not to. Executing JS in Java via Nashorn also an option but it'd be heavy weight.

JsonLogic
Having a standard way to share expressions does seem quite useful, especially when it's multilingual.

Question about setting up multiple applications using nginx.
Especially when dealing with more complex match rules, I personally much prefer Caddy's matchers over building some weird-ass if constructs in Nginx. It also supports CEL for request matching, giving you access to extremely powerful logic, if you need it.

JsonLogic
I did a rules engine to the company that I work based in this specification, but using go language. It is a very successful project because our clients can create rules without tech people around in our frontend, it's very easy to translate our rules into json and store it.
I even did a library to implement it in go language: https://github.com/diegoholiveira/jsonlogic
What are some alternatives?

json-logic-rs - JSONLogic implementation in Rust, accessible via Python and JS
dhall-lang - Maintainable configuration files
jaspr - Modern web framework for building websites in Dart. Supports SPAs and SSR.
secure-json-logic - Use logic-objects from uncertain sources and run them locally without breaking the own system
