Build Quality Gate Status Coverage

Refinery provides consistent graph model generation by partial model refinement.

See the Refinery tutorial for more information.

Visit to try our Graph-Solver-as-a-Service supported by the 2022 Amazon Research Award.

Running locally

To generate larger models with a longer timeout, you can use our Docker container on either amd64 or arm64 machines:

docker run --rm -it -p 8888:8888

Once Docker pulls and starts the container, you can navigate to http://localhost:8888 to open the model generation interface and start editing.

Alternatively, you can follow the instructions in to set up a local development environment and compile and run Refinery from source.
