Conjure is a simple but opinionated toolchain for defining APIs once and generating client/server interfaces in multiple languages.

Conjure was developed to help scale Palantir's microservice architecture - it has been battle-tested across hundreds of repos and has allowed devs to be productive in many languages.

Define your API once and then Conjure will generate idiomatic clients for Java, TypeScript, Python etc. The generated interfaces provide type-safe, clean abstractions so you can make network requests without worrying about the details.

For example in Java, Conjure interfaces allow you to build servers using existing Jersey compatible libraries like Dropwizard/Jetty.

The Conjure compiler reads API definitions written in the concise, human-readable YML format and produces a JSON-based intermediate representation (IR).

Conjure generators read IR and produce code in the target language. The associated libraries provide client and server implementations. Each generator is distributed as a CLI that conforms to RFC002:
