Synapse vs Trumpia: at a glance
What is Synapse?
A steady MSC-implementation train, interrupted by a ten-CVE security release.
Synapse is on its usual rhythm of release candidate followed by stable roughly every two weeks, with 1.158.0 shipping August 4. The substance sits in the 1.157 line: cancellable delayed events with a per-user cap, fully read markers that can move backwards, time filters on the admin redaction API, and the removal of deprecated MSC3861 auth delegation. That run was cut across on July 28 by 1.157.2, an out-of-band security release fixing six high-severity and several moderate advisories.
What is Trumpia?
Trumpia publishes SMS explainers weekly and product notes never — including the same post twice.
Ten entries, zero releases. The feed is SMS marketing education: KPIs to track, emoji meanings, what a drip campaign is, why customers opt in, how to switch RCS back to SMS, and an award mention. The KPI post appears twice within a week under the same title with near-identical copy, so the feed is duplicating its own content as well as carrying none from the product. Nothing here reveals what Trumpia has shipped.
Synapse vs Trumpia: editorial side-by-side
Synapse
5.0COMMS
A steady MSC-implementation train, interrupted by a ten-CVE security release.
◆ Current state
Synapse is on its usual rhythm of release candidate followed by stable roughly every two weeks, with 1.158.0 shipping August 4. The substance sits in the 1.157 line: cancellable delayed events with a per-user cap, fully read markers that can move backwards, time filters on the admin redaction API, and the removal of deprecated MSC3861 auth delegation. That run was cut across on July 28 by 1.157.2, an out-of-band security release fixing six high-severity and several moderate advisories.
◆ Where it's heading
The feature work is almost entirely Matrix spec implementation — MSC4140, MSC4446, MSC4388, MSC4354 sticky events over simplified sliding sync — which puts Synapse's direction downstream of the spec process rather than of its own product decisions. The operational thread is different and more telling: deprecated auth paths removed, Debian 12 packaging dropped, EDU sizes capped, admin tooling given finer controls. The server is being narrowed and hardened for federated deployments carrying untrusted users.
◆ Prediction
Expect the fortnightly candidate-then-stable cadence to hold and the next features to track whichever MSCs reach stabilization. The removal of MSC3861 and the Debian 12 drop suggest more deprecations are queued for operators to plan around.
Trumpia
5.0COMMS
Trumpia publishes SMS explainers weekly and product notes never — including the same post twice.
◆ Current state
Ten entries, zero releases. The feed is SMS marketing education: KPIs to track, emoji meanings, what a drip campaign is, why customers opt in, how to switch RCS back to SMS, and an award mention. The KPI post appears twice within a week under the same title with near-identical copy, so the feed is duplicating its own content as well as carrying none from the product. Nothing here reveals what Trumpia has shipped.
◆ Where it's heading
The consistent thread is defending SMS against RCS: the guide explaining how to turn RCS off frames plain SMS as the reliable, universally supported channel, and the rest of the content keeps attention on fundamentals a Trumpia customer already buys into. That is a retention posture rather than a product one. With no release notes in the window, there is no evidence of the product itself moving in any direction.
◆ Prediction
These entries support no prediction about the product — the feed carries marketing content only, so a real release would have to appear on a different channel before anything could be said about direction.
