Janus is an open source project, which means that there's an active Community you can interact with (e.g., to discuss deployment or runtime issues, potential new features, ideas and so on). Besides, our GitHub repo is the place to go when you find issues you think need to be solved, or whenever you've implemented something and want to contribute it back to the project.
That said, as a company we also provide additional services related to Janus, and that you might be interested in. If you think we can be of help, just contact us!
We do offer premium support for Janus-based deployments. Different options are available for different kinds of commercial grade support. Contact us to learn more.
We also offer training courses and tutoring on WebRTC, Janus, deployments, troubleshooting and so on. If you're interested in learning more, just get in touch.
Anything that doesn't fall in the above! We're quite flexible and can easily adapt to try and meet whatever your needs are. If you feel you need help, don't hesitate and tell us what you'd like us to do for you.
