What is PeerJS?

PeerJS keeps publishing release candidates that restate the same two fixes.

Every entry in PeerJS's feed is a release candidate, and each one repeats the bug list of the one before it — the unreliable close event and the data channel ordering fix appear in all four, spanning fourteen months. The genuinely new content per release is thin: a CSP fix removing the need for unsafe-eval, Blob support inside nested objects, and dependency updates. The most recent publication is from April 2024.

What is SRS?

SRS opens a 7.0 line built on a Go proxy tier, and drops features it no longer wants to carry.

SRS shipped the stable 6.0 line's first release on 12 August and, three hours later, the first development build of 7.0. The 6.0 line is now in pure maintenance — the r1 changelog is seven merges of DVR, WebRTC and edge fixes. Everything new is in 7.0-d0: RTSP playback, RTMPS, IPv6 across every protocol, HEVC in both directions between RTMP and WebRTC, and HLS fMP4 segments for HEVC and LL-HLS.

PeerJS vs SRS: editorial side-by-side

PeerJS
MEETINGS
0.0

PeerJS keeps publishing release candidates that restate the same two fixes.

◆ Current state

Every entry in PeerJS's feed is a release candidate, and each one repeats the bug list of the one before it — the unreliable close event and the data channel ordering fix appear in all four, spanning fourteen months. The genuinely new content per release is thin: a CSP fix removing the need for unsafe-eval, Blob support inside nested objects, and dependency updates. The most recent publication is from April 2024.

◆ Where it's heading

The changelog reads as a project maintained rather than developed, and one that never quite finishes a release cycle — candidates accumulate, notes carry forward, and stable releases do not appear in this feed. For a WebRTC wrapper this is a specific kind of risk: the browser layer underneath moves regardless, and the fixes that do land here are reactions to it, such as dropping unsafe-eval so the library survives strict Content Security Policies.

◆ Prediction

There is no signal in these entries about what comes next, and no publication in roughly two years; the honest read is that the release cadence has stopped rather than that a particular change is pending.

6.3

SRS opens a 7.0 line built on a Go proxy tier, and drops features it no longer wants to carry.

◆ Current state

SRS shipped the stable 6.0 line's first release on 12 August and, three hours later, the first development build of 7.0. The 6.0 line is now in pure maintenance — the r1 changelog is seven merges of DVR, WebRTC and edge fixes. Everything new is in 7.0-d0: RTSP playback, RTMPS, IPv6 across every protocol, HEVC in both directions between RTMP and WebRTC, and HLS fMP4 segments for HEVC and LL-HLS.

◆ Where it's heading

The project is trading breadth of legacy surface for a narrower, better-covered core. 7.0-d0 removes the embedded GB28181 SIP server, multi-threading, Cygwin, and most configuration hot reload, while introducing a Go proxy server and origin-cluster architecture alongside the C++ media core. Protocol coverage keeps generalizing — each release makes a codec or an address family a property of the server rather than of one delivery path.

◆ Prediction

Expect the 7.0 line to run a long alpha and beta train the way 6.0 did, with the Go proxy and origin clustering carrying most of the remaining work and 6.0 continuing to receive backported fixes in parallel.
