Why I Chose Rust Over C and C++ for Drengr

Why I Chose Rust Over C and C++ for Drengr I'm the creator of Drengr, an MCP server that gives AI agents eyes and hands on mobile devices. I started this blog to share the engineering behind it. No pretending to be a neutral observer writing a think piece — I built this, and I'm here to talk about it. When I tell people I built a mobile automation tool in Rust, the first question is always "why not Python?" I've written about that in a separate post. But the question that actually kept me up at night during the early architecture phase was different: why not C or C++?

It parses UI trees, captures screenshots, manages concurrent device sessions, and serves as an MCP server over stdio. This is systems programming territory. C and C++ have owned this space for decades. So why Rust? This isn't a "Rust vs C++" holy war post. I've worked with C and C++ in differen
