Replacing WebRTC
WebRTC is a widely-used technology for real-time media, data channels, and peer-to-peer communication on the web. While it has its strengths, it also has limitations that make it challenging to customize and adapt for different use cases. However, new APIs such as WebCodecs and WebTransport are being developed as possible replacements or enhancements to WebRTC. These new APIs provide more flexibility and control over media encoding/decoding and data transmission, respectively. While it will take time for these alternatives to reach feature parity with WebRTC, they show promise for improving the web development experience.
