Building Taskmaster: A Go-Powered Process Supervisor from Scratch

How two 42 School students reimagined process management with Go's concurrency model If you've ever managed a production server, you know the pain: a critical process crashes at 3 AM, no one notices until morning, and your users are left with a broken experience. Tools like Supervisor were built to solve this — but they come with Python overhead, complex configurations, and aging architectures. We decided to build our own. Taskmaster is a lightweight, production-ready process supervisor written in Go — and building it taught us more about operating systems, concurrency, and daemon design than any textbook could. What Is Taskmaster? Taskmaster is a process control daemon. It manages the full lifecycle of your processes — starting, stopping, restarting, and monitoring them — all through a simple interactive shell. Think of it as a modern, Go-native alternative to Supervisor or systemd service management, without the complexity. $ ./bin/taskmaster config.yaml Taskmaster> status Task Statu
