Vulcain

Open-source gateway that turns any REST API into a fast, client-driven API using HTTP/2 Preload and Early Hints.

PlatformWebfreeglobal

An open-source gateway, deployable as a Caddy module, that sits in front of an existing REST API and lets clients request exactly the related resources they need using HTTP Preload hints and Early Hints. It works with hypermedia and OpenAPI-documented APIs alike. Aimed at backend developers who want GraphQL-like flexible fetching without adopting GraphQL.
