The Clojure version is the reference implementation of the evaleval pattern: it builds the macro, signing, and JS DSL itself, with the cleanest separation of concerns and HMAC-SHA256. The Racket port is strong and native but slightly less polished (SHA1, manual syntax walk, fragile static-dir hack).

clojure-evaleval is the most complete and well-structured of all; clojure-buzz is clean but owes its design to the buzz framework.

clojure-evaleval implements the pattern end-to-end with the best code quality; python-evaleval relies on an external package and a clever-but-obscure DSL.

clojure-evaleval is the clear top of the ranking; python-web1 is the bottom.

clojure-evaleval implements its pattern end-to-end (server macro, HMAC signing, JS DSL) with the cleanest separation of concerns; durable-hop's contestant file is tidy, but the design is mostly the hop runtime's.
