OpenSIPS vs Switcher Studio

OpenSIPS vs Switcher Studio: at a glance
What is OpenSIPS?
OpenSIPS 4.0 is in release-candidate testing, with two RCs a month apart.
OpenSIPS, the open-source SIP proxy and server, has two tracked entries: 4.0.0-rc1 in May and 4.0.0-rc2 in June 2026. Both release notes are one-line announcements, so the specific 4.0 changes are not visible in the feed.
What is Switcher Studio?
Switcher Studio adds Instant Replay — a live broadcasting capability that finally closes the gap with dedicated sports streaming rigs.
Switcher Studio has shipped one substantive product feature in the visible window — Instant Replay, which allows broadcasters to replay the last few seconds of live footage mid-stream. The remaining entries are blog posts covering live streaming guides for sports events, NDI setup, OTT services, and camera settings. The product is primarily a mobile live production app targeting churches, schools, and sports organizations.

OpenSIPS
0.0MEETINGS
OpenSIPS 4.0 is in release-candidate testing, with two RCs a month apart.
◆ Current state
OpenSIPS, the open-source SIP proxy and server, has two tracked entries: 4.0.0-rc1 in May and 4.0.0-rc2 in June 2026. Both release notes are one-line announcements, so the specific 4.0 changes are not visible in the feed.
◆ Where it's heading
The product is moving toward a 4.0 major release through a standard RC cycle. A second RC a month after the first suggests stabilization work rather than new scope, but the entries do not say what 4.0 changes.
◆ Prediction
A 4.0.0 general release is the next expected step; what it contains cannot be read from these announcements.
Switcher Studio
6.3MEETINGS
Switcher Studio adds Instant Replay — a live broadcasting capability that finally closes the gap with dedicated sports streaming rigs.
◆ Current state
Switcher Studio has shipped one substantive product feature in the visible window — Instant Replay, which allows broadcasters to replay the last few seconds of live footage mid-stream. The remaining entries are blog posts covering live streaming guides for sports events, NDI setup, OTT services, and camera settings. The product is primarily a mobile live production app targeting churches, schools, and sports organizations.
◆ Where it's heading
The Instant Replay addition addresses a specific broadcast scenario (sports, live events) where the absence of replay was a hard limitation compared to professional streaming setups. Combined with the NDI guide content, Switcher appears to be deepening its presence in the sports broadcasting and multi-camera live event segment rather than expanding into adjacent markets.
◆ Prediction
Additional sports-broadcasting-specific features are likely: scoreboard overlays, multi-angle switching automation, or deeper NDI integration for more flexible camera setups without additional hardware.
