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 is selling real-time voice manipulation to contact centers, and the defense against it too.

Krisp ships a weekly web-update cadence for Call Center AI plus periodic desktop builds, and now folds them into a monthly recap. Recent substance sits in the weeklies: audit logs exposed through the portal API, Valencian added to Voice Translation, admin controls for translated-speech speed and a Spell mode for names and numbers, and Accent Conversion models running on both sides of a call. The monthly post adds no releases of its own, restating work the weekly entries already carried.

Dendrite vs Krisp: editorial side-by-side

D0.0

A forked, relicensed Dendrite spent its first year catching up on Matrix protocol and security debt

◆ 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 is selling real-time voice manipulation to contact centers, and the defense against it too.

◆ Current state

Krisp ships a weekly web-update cadence for Call Center AI plus periodic desktop builds, and now folds them into a monthly recap. Recent substance sits in the weeklies: audit logs exposed through the portal API, Valencian added to Voice Translation, admin controls for translated-speech speed and a Spell mode for names and numbers, and Accent Conversion models running on both sides of a call. The monthly post adds no releases of its own, restating work the weekly entries already carried.

◆ Where it's heading

The direction is real-time voice manipulation sold to contact centers, not consumers. Accent Conversion now runs on both sides of a call, translation gained speed control and a spelling mode, and the language list keeps growing. Voice Security is the defensive counterpart - the same synthesis capability that powers accent conversion is what makes deepfake detection necessary, and Krisp sells both sides. The steady stream of admin controls, audit logs and analytics portals shows an enterprise procurement checklist being worked through rather than a product still finding its shape.

◆ Prediction

Expect language and accent coverage to keep widening and Voice Security to move from paid trial toward general availability, with more of the admin surface following audit logs into the portal API.
