this is something I've been thinking of for a while - a micro DSL framework for diagrams with one implementation. I'll have a write-up about technology soonish, but in short - this prototype written with Haskell, no database, everything server-side rendered, frontend with Unpoly (pulled from CDN), HTML generated manually. Deployed as Cloudflare container with single request taking approx. 0.8ms time.

Note: because it's using naive load balancing there might be some jank as containers wake up.

No data gathering whatsoever outside of requests and also some debug output from parser.
