A developer has released a web-based version of the popular Mars MIPS simulator featuring an integrated C compiler, accessible at webmars.nfiles.top. The project brings the widely-used MIPS assembly education tool to browsers without installation requirements, now extended with C language support for compiling directly to MIPS assembly.

Mars MIPS has long been a staple in computer architecture courses for teaching MIPS assembly language programming and simulation. This web port eliminates platform barriers, allowing students and educators to run MIPS programs instantly on any device with a browser. The addition of a built-in C compiler streamlines the workflow from high-level code to assembly visualization.

The Hacker News submission garnered 12 points and 4 comments, indicating early community interest. Users can write C code, compile it to MIPS assembly, and execute it within the same interface — bridging the gap between C programming and low-level architecture concepts. This integration supports educational workflows where instructors demonstrate how C constructs translate to assembly instructions.

The project represents a modern take on classic educational tooling, leveraging WebAssembly or JavaScript compilation targets to deliver near-native performance in a zero-install environment.
