Pion WebRTC v4.0.0 has been released! See the release notes to learn about new features and breaking changes.
If you aren't able to upgrade yet check the tags for the latest v3 release.
We would love your feedback! Please create GitHub issues or join the Slack channel to follow development and speak with the maintainers.
Go Modules are mandatory for using Pion WebRTC. So make sure you set export GO111MODULE=on, and explicitly specify /v4 (or an earlier version) when importing.
example applications contains code samples of common things people build with Pion WebRTC.
example-webrtc-applications contains more full featured examples that use 3rd party libraries.
awesome-pion contains projects that have used Pion, and serve as real world examples of usage.
GoDoc is an auto generated API reference. All our Public APIs are commented.
FAQ has answers to common questions. If you have a question not covered please ask in Slack we are always looking to expand it.
Now go build something awesome! Here are some ideas to get your creative juices flowing:
- Send a video file to multiple browser in real time for perfectly synchronized movie watching.
- Send a webcam on an embedded device to your browser with no additional server required!
- Securely send data between two servers, without using pub/sub.
- Record your webcam and do special effects server side.
- Build a conferencing application that processes audio/video and make decisions off of it.
- Remotely control a robots and stream its cameras in realtime.
Check out WebRTC for the Curious. A book about WebRTC in depth, not just about the APIs. Learn the full details of ICE, SCTP, DTLS, SRTP, and how they work together to make up the WebRTC stack. This is also a great resource if you are trying to debug. Learn the tools of the trade and how to approach WebRTC issues. This book is vendor agnostic and will not have any Pion specific information.
Pion has an active community on Slack. Please ask for help about anything, questions don't have to be Pion specific! Come share your interesting project you are working on. We are here to support you.
One of the maintainers of Pion Sean-Der is available to help. Schedule at siobud.com/meeting He is available to talk about Pion or general WebRTC questions, feel free to reach out about anything!

The library is in active development, please refer to the roadmap to track our major milestones. We also maintain a list of Big Ideas these are things we want to build but don't have a clear plan or the resources yet. If you are looking to get involved this is a great place to get started! We would also love to hear your ideas! Even if you can't implement it yourself, it could inspire others.
Work on Pion's congestion control and bandwidth estimation was funded through the User-Operated Internet fund, a fund established by NLnet made possible by financial support from the PKT Community/The Network Steward and stichting Technology Commons Trust.
Pion has an active community on the Slack.
Follow the Pion Twitter for project updates and important WebRTC news.
We are always looking to support your projects. Please reach out if you have something to build! If you need commercial support or don't want to use public methods you can contact us at [email protected]
