24 alternatives to C++ Compiler Support Page

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…

The C++ Compiler Support Page is a searchable reference tool that displays C++ features from C++20 onwards in a structured table format. Designed for C++ developers, it helps track compiler support across platforms and… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

I built a small browser engine from scratch in C++▲146
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…

Single-Header Profiler for C++17▲68
Morning HN. I often found myself wondering "how much does this code segment take in terms of total runtime" and it's often quite annoying to figure out with optimizations enabled, especially when working on something new or testing someone else's implementation without the proper tooling set up. Wanted to have a single include lib that would allow us to write something like: ``` PROFILE("Loop 1") for (...) // some work ``` and have the next expression automatically record time & dump results to a table. Wrote a few macros to do exactly that a few months back, but they were…

C/C++ Cheatsheet – a modern, practical reference for C and C++▲10
Hi HN, I’m the creator of C/C++ Cheatsheet — a modern, practical reference for both C and C++ developers. It includes concise snippet-style explanations of core language features, advanced topics like coroutines and constexpr, system programming sections, debugging tools, and useful project setups. You can explore it online at https://cppcheatsheet.com/. I built this to help both beginners and experienced engineers quickly find clear examples and explanations without digging through fragmented blogs or outdated docs. It’s open source, regularly maintained, and…

I built a Cargo-like build tool for C/C++▲177
I love C and C++, but setting up projects can sometimes be a pain. Every time I wanted to start something new I'd spend the first hour writing CMakeLists.txt, figuring out find_package, copying boilerplate from my last project, and googling why my library isn't linking. By the time the project was actually set up I'd lost all momentum. So, I built Craft - a lightweight build and workflow tool for C and C++. Instead of writing CMake, your project configuration goes in a simple craft.toml: [project] name = "my_app" version = "0.1.0" language = "c" c_standard = 99 [build] type = "executable"…

A C++ web/application framework I have been building for the last 12yrs▲29
Back then there were not a lot of frameworks for C++ like there are available now, gradually added serialization, reflection, orm, modules for apache|nginx, then started adding programming language integration and then finally added support for building on various Os'es and also support for most of the build tools out there.

Modifying Clang for a Safer, More Explicit C++▲76
Modified C++ Inspired by the paper "Some Were Meant for C" by Stephen Kell, I decided to show that it's possible to iterate C++ to be safer, more explicit, and less error-prone. Here's a possible starting point: I didn't invent a new language or compiler, but took the world's best compiler, clang, and modified it to begin iterating towards a new furture of C++. Naming things is hard, so I call this 'Modified C++'. Some of the following could be implemented as tooling in a linter or checker, but the idea is to update the compiler directly. I also wanted to learn more about clang. This…

CXXStateTree – A modern C++ library for hierarchical state machines▲48
Hi HN! I've built [CXXStateTree](https://github.com/ZigRazor/CXXStateTree), a modern C++ header-only library to create hierarchical state machines with clean, intuitive APIs. It supports: - Deeply nested states - Entry/exit handlers - State transitions with guards and actions - Asynchronous transitions with `co_await` (C++20 coroutines) - Optional runtime type identification for flexibility It's ideal for complex control logic, embedded systems, games, robotics, and anywhere you'd use a finite state machine. I’d love feedback, use cases, or contributions from the…

C++17 In Detail, a book that will move you from C++11/14 to C++17▲12
Hi! Last year in August I've released my first self-published book. C++17 In Detail Available at Leanpub: https://leanpub.com/cpp17indetail Keeping up with the latest changes in the language is quite hard. C++ moves quite fast recently, and there are many exciting features added with each iteration. The book shows all the significant changes in the language and the Standard Library. The chapters are much easier to grasp than reading reference pages or the Standard itself. It's a great guide for any C++ developer who knows a little about C++11/14 and wants to move forward.…
