I was impressed by bun from the very beginning, and that continued until I needed to use native GPU calls. I had to switch to Node.js subprocesses.

When comparing Bun and Node.js for my tasks, I keep finding more advantages in Bun’s optimizations. I'll handle GPU processes through BFFI. Node.js is also prone to unstable memory behavior with native processes, so it doesn’t make sense to use it as an extra layer.

For those looking for stability, Node.js is definitely the better choice.
