OpenSIPS vs Restream
A side-by-side editorial comparison of OpenSIPS and Restream — release velocity, themes, recent moves, and the top alternatives to consider.
OpenSIPS vs Restream: 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 Restream?
Restream's chat now keeps the full history and shows Super Chats and other stream alerts.
Restream's recent releases are about what happens around a stream rather than the encode itself. The November 8 update keeps every chat message, even when chat is opened late or gets thousands of messages, and shows stream alerts such as YouTube Super Chats and memberships, X follows and Kick subscriptions in the same panel. It follows Instagram Live by account connection with chat, and the Claude connector.

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.
Restream
5.0MEETINGS
Restream's chat now keeps the full history and shows Super Chats and other stream alerts.
◆ Current state
Restream's recent releases are about what happens around a stream rather than the encode itself. The November 8 update keeps every chat message, even when chat is opened late or gets thousands of messages, and shows stream alerts such as YouTube Super Chats and memberships, X follows and Kick subscriptions in the same panel. It follows Instagram Live by account connection with chat, and the Claude connector.
◆ Where it's heading
The product is moving from a relay that forwards a video feed to a hub that owns the account connections, the audience data and the follow-up. Each release removes a manual step: stream keys, attendee lists, clip posting, and now opening the dashboard at all.
◆ Prediction
Expect more destinations to move from stream-key relay to direct account connections with chat, following the X and Instagram pattern. Whether the Claude connector grows into scheduled or automated stream workflows is not yet visible in the entries.
