Synapse vs VerneMQ: at a glance
What is Synapse?
Synapse 1.164 advertises Matrix v1.16 and v1.17 amid a run of dependency security patches
Synapse keeps its two-to-three-week cycle of candidates and stables. 1.164.0 went stable on 27 October with support for Matrix v1.16 and v1.17 and a dedicated endpoint for scheduling delayed events (MSC4140). The surrounding releases are security dependency bumps: certifi, a rustls-webpki update that distrusts the compromised eMudhra intermediate CAs, Pillow 13.0.0 for critical image-handling flaws, and msgpack against memory exhaustion on the public room list.
What is VerneMQ?
VerneMQ follows its year-in-the-making 2.2.0 with a quick round of subscription fixes.
VerneMQ releases infrequently; 2.2.0 on August 9 gathered about a year of cluster and connection work, including a socket-counting fix under rapid reconnects and faster inter-node readiness checks. 2.2.1 on October 16 followed with fixes for stale shared subscriptions after trie restarts, enforcement of non-zero message ids, and new webhook connect options.

Synapse 1.164 advertises Matrix v1.16 and v1.17 amid a run of dependency security patches
◆ Current state
Synapse keeps its two-to-three-week cycle of candidates and stables. 1.164.0 went stable on 27 October with support for Matrix v1.16 and v1.17 and a dedicated endpoint for scheduling delayed events (MSC4140). The surrounding releases are security dependency bumps: certifi, a rustls-webpki update that distrusts the compromised eMudhra intermediate CAs, Pillow 13.0.0 for critical image-handling flaws, and msgpack against memory exhaustion on the public room list.
◆ Where it's heading
The homeserver tracks the spec closely, stabilising MSCs as they land in Matrix releases, while backporting each security bump to the previous stable line. Sticky Events and User Status work suggest continued alignment with newer client features.
◆ Prediction
1.165 release candidates should follow within about two weeks, likely with further MSC stabilisations.
VerneMQ
2.5COMMS
VerneMQ follows its year-in-the-making 2.2.0 with a quick round of subscription fixes.
◆ Current state
VerneMQ releases infrequently; 2.2.0 on August 9 gathered about a year of cluster and connection work, including a socket-counting fix under rapid reconnects and faster inter-node readiness checks. 2.2.1 on October 16 followed with fixes for stale shared subscriptions after trie restarts, enforcement of non-zero message ids, and new webhook connect options.
◆ Where it's heading
Two months between 2.2.0 and 2.2.1 is quick for this project, which suggests 2.2 is getting active maintenance. The work stays inside the broker: subscriptions, clustering and protocol correctness rather than new features.
◆ Prediction
Further 2.2.x patches are more likely than a new minor; the feed gives no sign of 2.3 work.
