I finished the rewrite in just a few months and have been happily maintaining it for two years and extending it with powerful features it never had before, partially thanks to optimized native binary speed, partially thanks to the ludicrous compatibility of a musl-libc static binary. The rewrite is the backend foundation of a web product stack that is best-in-category.

I didn't choose Nim because I was an evangelist; I had only toyed with it twice before. After much evaluating (and wrestling an ultra-frustrating previous attempt at a Rust rewrite my predecessor had tried), Nim surfaced as the best tool for the specific job. And it still is. It doesn't have to be our entire product stack; it's doing a small subset of very important jobs, doing them well, and is invoked by other languages that do their jobs better as web servers and such. A modular stack helps each language and tool shine where it works best.
