About Us
Built for everyone,
by developers who care
MES-DEV is a software development studio. We build practical desktop and web applications that help people work smarter and faster — from students and teachers to business owners, job seekers, developers, designers, and beyond.
Our story
MES-DEV started as a personal project to solve a simple frustration — running Python scripts required too many tools. So we built Python Code Runner, a clean desktop app that handles everything in one place.
When other developers started asking for it, we realized there was real demand for simple, focused tools. Today we ship multiple apps following the same philosophy: free core, premium power.
