What is Dendrite?
A forked, relicensed Dendrite spent its first year catching up on Matrix protocol and security debt
The window opens with the first release after forking from matrix-org/dendrite under AGPLv3, which fixed long-standing state-reset bugs and added I2P and Onion listening. What follows is a security release closing a server-side request forgery vulnerability, then a release adding room version 12 support and two MSC implementations, and finally two quick patches for unresponsiveness, v12 room joins and malformed PDUs blocking whole transactions.
What is Krisp?
Krisp turned noise cancellation into a contact-center AI stack — and now defends it against deepfakes.
Krisp's changelog is almost entirely Call Center AI: Accent Conversion, Voice Translation, Speech Analytics, and a Voice Security line that detects synthetic voices and verifies agents. The release rhythm is two-track — versioned desktop builds carrying model upgrades, and near-weekly web batches carrying admin, analytics, and access controls. Most of the recent web work is aimed at administrators rather than agents on the phone.

◆ Current state
The window opens with the first release after forking from matrix-org/dendrite under AGPLv3, which fixed long-standing state-reset bugs and added I2P and Onion listening. What follows is a security release closing a server-side request forgery vulnerability, then a release adding room version 12 support and two MSC implementations, and finally two quick patches for unresponsiveness, v12 room joins and malformed PDUs blocking whole transactions.
◆ Where it's heading
This is a fork proving it can carry a homeserver. The order is telling: license and state correctness first, then a CVE, then protocol currency with room version 12, then the operational bugs that surface once people actually run it. Several fixes carry outside contributor credits, which is the fork's clearest sign of life.
◆ Prediction
Expect continued protocol catch-up on newer MSCs and room versions plus operational fixes, since federation compatibility is the constraint that sets this project's agenda.
Krisp
5.0COMMS
Krisp turned noise cancellation into a contact-center AI stack — and now defends it against deepfakes.
◆ Current state
Krisp's changelog is almost entirely Call Center AI: Accent Conversion, Voice Translation, Speech Analytics, and a Voice Security line that detects synthetic voices and verifies agents. The release rhythm is two-track — versioned desktop builds carrying model upgrades, and near-weekly web batches carrying admin, analytics, and access controls. Most of the recent web work is aimed at administrators rather than agents on the phone.
◆ Where it's heading
The center of gravity has shifted from processing the audio to governing the operation around it. Voice Security opened a second buying reason beyond call quality, and the newer web releases — enterprise analytics sharing, agent screen recording, audit and access controls, automated data retention cleanup — read as a BPO-facing compliance layer taking shape. Krisp is positioning as infrastructure a contact center buys once and administers, not a per-seat audio utility.
◆ Prediction
Voice Security has moved from launch to paid trial in roughly six weeks, so expect it to reach general availability with pricing attached as the next step. The analytics and recording work points the same direction: more supervisor-facing surfaces bundled into the enterprise portal rather than new agent-side audio features.
