24 alternatives to Otterkit – COBOL compiler for .NET
I'm the lead developer of Otterkit. We've been working on this compiler for the past few months. The goal is to support the latest COBOL 2022 standard and compile it to C# (will support nativeAOT as well) Currently most of the work is being done on the parsing side of it to ensure that it can correctly parse all of the 2022 standard. We're almost done writing the parser, and will soon move to the codegen and runtime library. Please let me know what your opinion is on the project. I'll be here to answer any questions about it. We're also looking for contributors if anyone is interested in…
Otterkit is a COBOL compiler for .NET that converts COBOL 2022 standard code to C#, with planned support for nativeAOT compilation. Built for developers maintaining or modernizing legacy COBOL systems, it targets… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Otterkit – COBOL compiler for .NET launched in 2023; newer entries below may have overtaken it.

This is an evolving toolkit of capabilities helpful for analysing and reverse engineering legacy Cobol code. Currently, the following capabilities are available: - Program / Section-level flowchart generation based on AST (SVG or PNG) - Parse Tree generation (with export to JSON) - Control Flow Tree generation (with export to JSON) - Allows embedding code comments as comment nodes in the graph - The SMOJOL Interpreter (WIP) - Injecting AST and Control Flow into Neo4J - Injecting Cobol data layouts from Data Division into Neo4J (with dependencies like MOVE, COMPUTE, etc.) + export to…

Hey HN! I’ve been building OtterLang, a small experimental scripting language designed to feel like Python but compile down to native binaries through LLVM. The goal isn’t to reinvent Python or Rust, but to find a middle ground between them: Python-like readability and syntax Rust-level performance and type safety Fast builds and transparent Rust FFI (you can directly import Rust crates without writing bindings) OtterLang is still early and very experimental. the compiler, runtime, and FFI bridge are being rewritten frequently. Please star the repo, and contribute to help this project.

Hi HN! Korean high school senior here, about to start CS in college. I built a browser engine from scratch in C++ to understand how browsers work. First time using C++, 8 weeks of development, lots of debugging—but it works! Features: - HTML parsing with error correction - CSS cascade and inheritance - Block/inline layout engine - Async image loading + caching - Link navigation + history Hardest parts: - String parsing(html, css) - Rendering - Image Caching & Layout Reflowing What I learned (beyond code): - Systematic debugging is crucial - Ship with known bugs rather than chase…

Hi HN! I’m Tony, one of the co-founders of Inngest (https://inngest.com/). Wanted to show you something we’re working on: StepKit. StepKit is an open source SDK and framework for building and iterating on durable workflows that run on any platform (self-hosted, Inngest, Cloudflare, Netlify, etc.) without requiring any provider or bundler-specific code. Here’s the repo: https://github.com/inngest/stepkit. StepKit extracts the core execution loop that we built in Inngest and makes it fully open, Apache 2, and hackable/pluggable to different backends. We…

Hi HN, I have created a webpage that displays all C++ features since C++20 in a simple, searchable table. It is intended to serve as a quick reference for C++ developers, whether as support for cross-platform development or simply to track the current support status out of curiosity. I created it as a simpler, more structured, and more up-to-date alternative to the cppreference compiler support site. Please note that the page intentionally does not list LWG and CWG papers. This might change as I am continually updating the site and trying out new ideas. Questions, feedback and suggestions…

I built Copapy as an experiment: Can Python be used for hard real-time systems? Instead of an interpreter or JIT, Copapy builds a computation graph by tracing Python code and uses a custom copy-and-patch compiler. The result is very fast native code with no GC, no syscalls, and no memory allocations at runtime. The copy-and-patch compiler currently supports x86_64 as well as 32- and 64-bit ARM. It comes as small Python package with no other dependencies - no cross-compiler, nothing except Python. The current focus is on robotics and control systems in general. This project is early but…

Hey HN! I’m Zach, from Coherence (https://www.withcoherence.com/). We’re building software that provides an integrated way to write, preview, and deploy code from one simple configuration. Check out our explainer video here: https://www.youtube.com/watch?v=V2YHVx8QsLg and a high level demo here: https://www.loom.com/share/072c2afd1099496298f69ab21fdf2820 We started Coherence because we found technology teams spent 30-40% of their time yak shaving and writing glue code, instead of building products our customers love. We don’t think every team…
