Why I Left Python for Nim — And Never Looked Back

“Sometimes, the best tools are the ones no one’s talking about.”

👋 My Journey with Python

For years, Python was my go-to language. It’s clean, readable, and has a massive ecosystem. I used it for everything — from scripting and automation to web development and even dabbling in machine learning. But as my projects grew, I started to feel the cracks.

Scripts got slower.
Packaging became a nightmare.
Deploying apps meant dealing with virtual environments, dependency hell, and bloated runtimes.

I loved Python, but I needed something leaner, faster, and more predictable.

⚡ Enter Nim

I stumbled upon Nim by accident. At first glance, it looked like a mix of Python and something lower-level like C. But the more I explored, the more I realized: this is what I’ve been looking for.

Here’s what blew me away:

🧠 Python-like syntax — Clean, readable, and beginner-friendly.
🚀 Compiled to native code — Nim compiles to C, C++, or JavaScript. That means blazing-fast performance.
📦 No runtime bloat — You get tiny, standalone binaries. No need for interpreters or virtual environments.
🛠️ Low-level power — You can go deep when you need to, just like in C.
🌍 Cross-platform — Write once, run anywhere.

🧪 Real-World Impact

I rewrote one of my Python CLI tools in Nim. The results?

Execution time: 5x faster
Binary size: From 20MB (Python + dependencies) to under 1MB
Deployment: Just copy the binary. That’s it.

It felt like magic.

🤔 So Why Isn’t Everyone Using Nim?

Honestly? I think it’s just under the radar. Nim doesn’t have the marketing machine behind it like Rust or Go. But that’s changing — and I want to be part of that change.

💬 Final Thoughts

I’m not saying Nim will replace Python for everyone. But if you’re tired of slow scripts, heavy runtimes, or just want to try something new — give Nim a shot.

This is just the beginning. I’ll be sharing more about my journey with Nim, including tutorials, projects, and tips. Stay tuned.
