SRS vs FreeSWITCH
A side-by-side editorial comparison of SRS and FreeSWITCH — release velocity, themes, recent moves, and the top alternatives to consider.
SRS vs FreeSWITCH: at a glance
What is SRS?
SRS 6.0 went stable by making H.265 work everywhere, not just in one protocol.
SRS shipped 6.0 release 0 in December 2025, promoting the 6.0 line to stable in place of 5.0 at roughly 170,000 lines of code. The headline is H.265/HEVC carried across RTMP, HTTP-FLV, HLS, HTTP-TS and SRT, with DVR recording to both MP4 and FLV. WebRTC gained WHEP for playback, stereo Opus over SDP and a configurable AAC-to-Opus bitrate; SRT moved to libsrt 1.5.3 with round-trip latency reported down to 200ms.
What is FreeSWITCH?
After twenty-one months of silence, FreeSWITCH 1.11 deleted thirty legacy modules and moved on
The 1.11 line arrived in May 2026 after the 1.10 series had gone quiet since August 2024. Its opening release migrated to PCRE2, upgraded Windows to OpenSSL 3.x, added Debian 13 support and removed roughly thirty legacy modules. The follow-up three weeks later added a reloadcert API for hot TLS certificate reloads across mod_sofia and mod_verto without dropping calls, plus SIP 603 detection and passthrough control.

0.0MEETINGS
SRS 6.0 went stable by making H.265 work everywhere, not just in one protocol.
◆ Current state
SRS shipped 6.0 release 0 in December 2025, promoting the 6.0 line to stable in place of 5.0 at roughly 170,000 lines of code. The headline is H.265/HEVC carried across RTMP, HTTP-FLV, HLS, HTTP-TS and SRT, with DVR recording to both MP4 and FLV. WebRTC gained WHEP for playback, stereo Opus over SDP and a configurable AAC-to-Opus bitrate; SRT moved to libsrt 1.5.3 with round-trip latency reported down to 200ms.
◆ Where it's heading
The eighteen months of alpha and beta tags before release 0 were overwhelmingly crash, leak and iterator fixes — smart-pointer conversions, use-after-free repairs in the HLS and bridge paths, RTC-to-RTMP stability. That is the signature of a project stabilizing an existing engine rather than extending it, with the codec work landing at the end. SRS is positioning as the self-hosted streaming server that speaks every ingest and egress protocol in one binary.
◆ Prediction
With 6.0 now the stable line, the pattern from the 5.0 era points to a run of 6.0 patch releases carrying fixes rather than features. The entries give no indication of what the next major line targets.
FreeSWITCH
0.0MEETINGS
After twenty-one months of silence, FreeSWITCH 1.11 deleted thirty legacy modules and moved on
◆ Current state
The 1.11 line arrived in May 2026 after the 1.10 series had gone quiet since August 2024. Its opening release migrated to PCRE2, upgraded Windows to OpenSSL 3.x, added Debian 13 support and removed roughly thirty legacy modules. The follow-up three weeks later added a reloadcert API for hot TLS certificate reloads across mod_sofia and mod_verto without dropping calls, plus SIP 603 detection and passthrough control.
◆ Where it's heading
The 1.11 releases read as deferred maintenance being paid down in one move: regex library, TLS stack, supported distributions and dead module surface all changed together after a long gap. The reloadcert work points at the same audience — operators who cannot take an outage to rotate a certificate. This is consolidation for long-running production switches, not feature expansion.
◆ Prediction
Expect further 1.11.x releases continuing the security-and-stability framing, with attention on modules affected by the PCRE2 and OpenSSL 3 migrations as deployments upgrade.
