Webhooks, scraping, health checks, proxying. Every language solves outbound HTTP with an external library. In Fitz, http.get/post/put/delete/head/request are language builtins. Async from day one. Bit-for-bit parity between the interpreter and the native binary. No pip install requests / npm install axios / cargo add reqwest required.
The forgotten detail
Fitz has had @get/@post since Phase 4. Serving HTTP is trivial. But until last week, if your handler needed to call another service (Slack webhook, scraping, health check, proxying to an upstream), you had two options:
Import Python with from python import urllib.request and bundle CPython (~22 MB extra to the binary).
Don't do it.
