A C/C++ IDE written in C from scratch with zero dependencies

I’ve spent the last ~2 years building a C/C++ IDE for Windows entirely in C99. My goal was to eliminate the bloat of the modern Visual Studio environment keeping its core features. Key Technical Highlights: Zero Dependencies: Just the Windows API Performance: Starts in 0.1ms on a twelve year old machine. It handles projects with 500k+ lines without UI lag or indexing stutters. Integrated Tools: Includes a custom-built debugger, profiler, and Intellisense engine designed for speed. Portability: It’s a single executable. No installer required. I built this because I was tired of waiting…

A C/C++ IDE written in C from scratch with zero dependencies launched on March 22, 2026 with 10 votes, #1,177 of 23,380 launches that month and more than 90% of that year's launches.

In plain words

This is a C/C++ IDE built entirely in C99 for Windows, designed as a lightweight alternative to Visual Studio. It runs as a single portable executable with no external dependencies, starting in milliseconds and handling large projects with thousands of lines of code without lag. The IDE includes an integrated debugger, profiler, and code completion engine optimized for speed. It targets developers who want core IDE features without the resource overhead of conventional development environments.

  • I built a small browser engine from scratch in C++Jan 2026 · github.com · ▲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…

  • I built a Cargo-like build tool for C/C++Apr 2026 · github.com · ▲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"…

    GitHub repo: https://github.com/ArcadeMakerSources/ArcadeMaker (first of all, i want to say that I made this project for fun and challenge. I always wanted to create my own language. This has no business goal or something.) So the project is a 2D game engine (MonoGame backend) inspired by GameMaker 8. It includes its own IDE (built with WinForms) and an interpreted programming language that I wrote myself. The language—definitely the biggest challenge in the project—is a simple dynamically typed language. When I started, I had zero knowledge of how to build something like…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
