Okapi Bridge

The Okapi bridge — a JVM plugin daemon that exposes the Okapi Framework's Java filters over the kapi plugin protocol — is developed in its own repository: neokapi/okapi-bridge.

It is no longer part of the product surface. Its role today is keeping the plugin protocol honest: it is the reference implementation of a third-party kapi plugin in a non-Go language, and its CI runs the protocol conformance suite against released kapi versions.

The plugin protocol — the manifest model, the three transports, and the gRPC services a daemon serves — is specified in Plugin protocol v1, with its rationale in Plugin system. Any plugin repository can verify itself against that contract with the conformance suite the spec describes.
