Based on the knowledge sources provided, I don't see specific information about the availability of JWT (JSON Web Token) functionality in self-hosted Ory Hydra as referenced in your link. However, I can confirm that Ory Hydra is available as an open-source self-hosted solution. The documentation shows that you can deploy Ory Hydra in various self-hosted environments: 1. You can install Ory Hydra on different operating systems: - Linux: using bash installation script - macOS: using Homebrew - Windows: using Scoop - Or download binaries directly from GitHub releases [Self-hosted Installation](https://www.ory.sh/docs/hydra/self-hosted/install) 2. You can run Ory Hydra using Docker:

docker pull oryd/hydra:<version-you-want>    docker run --rm -it oryd/hydra:<version-you-want> help

[Run Ory Hydra in Docker](https://www.ory.sh/docs/hydra/self-hosted/configure-deploy#deploy-ory-hydra) 3. There's also a Kubernetes Helm Chart available for deploying Ory Hydra on Kubernetes [Kubernetes Helm Chart](https://www.ory.sh/docs/hydra/self-hosted/kubernetes-helm-chart) The knowledge sources mention that Ory Hydra generates JSON Web Key Sets for various purposes including "hydra.jwt.access-token", which suggests JWT functionality is available in the self-hosted version, but I cannot definitively confirm the specific JWT functionality referenced in your link based on the provided knowledge sources. If you need specific details about JWT functionality in self-hosted Ory Hydra, I would recommend checking the documentation at the link you provided or reaching out to the Ory community on Slack as mentioned in the installation guide.
