I need a web-based compiler that lets me write, build, run, and debug C and C++ code directly in the browser through an interface that feels like a lightweight IDE. When users visit the page—from Windows, macOS, or Linux—they should see a split-pane editor, an output/terminal window, and an error list, all updating in real time. The editor must come with syntax highlighting, smart auto-completion, and breakpoint-level debugging for both languages. Compile and execution should happen in an isolated, secure backend (Docker, container sandbox, WebAssembly, or a similar approach) using modern toolchains such as GCC / Clang, without noticeable lag. Deliverables: • Fully deployable web app packaged for one-command Docker setup • IDE-style front end with highlighting, completion, and step-by-step debugging • Reliable support for C17 and C++20 standards • Clear README covering installation, architecture, and instructions to add future languages • Quick demo (video or GIF) proving it works on Windows, macOS, and Linux browsers I’ll supply the hosting environment; just make sure everything is cleanly documented and maintainable. If you have ideas to improve performance, security, or usability, include them in your approach.
