Federation-compatible subgraph implementations

For use in a federated supergraph

The following open-source GraphQL server libraries and hosted solutions support acting as a subgraph in a federated supergraph. Their support is tracked in Apollo's subgraph compatibility repository. Check out the repository for details on the compatibility tests listed in the table below.
