Pretty far from my area of expertise. BTW. I have 0 expectation that someone has to solve my problem but when looking at a lang to me the minimum req. are good PG support and decent http lib which is obviously not the requirements people actively working on Nim have.

Nim forum is written in pure Nim[1] and is using httpbeast[2] as a backend.

In terms of features it's powerful enough to build a Discourse-like forum enough. In terms of performance it's very well performing in the TechEmpower benchmarks[3] it is competing in. It even grabbed first place on JSON serialization on Cloud hardware.

OK english is not my native lang so maybe I am not formulating things clearly I did not try to suggest that nim does not have good http lib. I was just saying my 2 core requirements good http lib and high quality mature PostgreSQL driver. Nim has good Http lib Nim does not have async PG driver that I would feel confident using in prod.

The D forum is also written in D (it's called DFeed, IIRC), and it's fast (anecdotally).
