4. ANTLR

   3 20 18,978 5.5 Java

   ANTLR (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing, or translating structured text or binary files.

   

   Project mention: RCParsing VS ANTLR - a user suggested alternative | libhunt.com/r/RCParsing | 2025-09-19

   ANTLR is a lexer-based, powerful tool for creating own DSL and analyzing them. But it's and overkill for simple languages (JSON, for example), while RCParsing is good for both complex and simple languages, allows you to choose: work with AST or immediately calculate value while parsing.

5. aws-doc-sdk-examples

   4 19 10,448 9.6 Java

6. QR-Code-generator

   5 27 6,669 5.8 Java

   Project mention: Fully vector QR codes with an SVG logo in React (download as scalable SVG) | dev.to | 2026-06-08

   That's what react-quick-response does. It renders the QR code as SVG (the encoding is handled by Project Nayuki's well-known QR Code generator library, bundled in — no extra runtime dependency), and it lets you pass an SVG logo as a child that stays vector too.

7. Zeppelin

   6 12 6,651 9.4 Java

   Web-based notebook that enables data-driven, interactive data analytics and collaborative documents with SQL, Scala and more.

   

   Project mention: Woxi: Wolfram Mathematica Reimplementation in Rust | news.ycombinator.com | 2026-02-25

   I wonder if it would make a good Zeppelin interpreter. https://zeppelin.apache.org/

8. spotless

   7 16 5,610 9.6 Java

   Keep your code spotless

   

   Project mention: The Judgement Pyramid: Reasoning vs Measurement | dev.to | 2026-05-19

   Is this reasoning, or measurement? If measurement, push it to a deterministic tool. Sonar, Spotless, Ruff, ESLint, coverage gates, pre-commit hooks, complexity calculators. Write a script if no tool exists. That's how just lint got built, and that's the Unix-philosophy move for agentic coding. Hooks fire on tool calls; CI fires on PRs; pre-commit fires on commit. Pick the cheapest layer that catches the failure and run it there.

9. fory

   8 37 4,493 9.8 Java

   A blazingly fast multi-language serialization framework for idiomatic domain objects, schema IDL, and cross-language data exchange.

12. teavm

    11 45 3,087 9.4 Java

    Compiles Java bytecode to JavaScript, WebAssembly and C

    

    Project mention: My determinism test passed for months while the two builds played different games | dev.to | 2026-08-01

    The rules live in one module with no Android on its classpath, which is what let me compile them a second time with TeaVM and run the same logic on a canvas in a browser tab.

13. Thymeleaf

    12 39 2,977 8.5 Java

    Project mention: WASM 3.0 Completed | news.ycombinator.com | 2025-09-17

    Well, for Java it's actually a separate compiler that targets Wasm and integrates with WasmGC: https://github.com/google/j2cl The Google Sheets team used it for their calc engine: https://v8.dev/blog/wasm-gc-porting

    For Kotlin it's similar but the compiler backend is from Jetbrains themselves, targets Wasm and adapts the Kotlin runtime to use WasmGC: https://kotlinlang.org/docs/wasm-overview.html. https://seb.deleuze.fr/introducing-kotlin-wasm/ has some low level detail on how Kotlin works with WasmGC.

    A bit more on Kotlin/Wasm here, seems like also Dart/Flutter uses WasmGC: https://developer.chrome.com/blog/wasmgc#kotlin_wasm

    https://github.com/dotnet/runtime/issues/94420 has some notes on why C# can't use WasmGC (yet?).
