Dendrite vs Notion
A side-by-side editorial comparison of Dendrite and Notion — release velocity, themes, recent moves, and the top alternatives to consider.
Dendrite vs Notion: at a glance
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 Notion?
Notion is turning its workspace into an orchestration layer for external AI agents.
Notion has moved well past docs-and-wikis: the 3.5 Developer Platform and 3.6 release reposition it as an orchestration layer where external agents like Claude and Cursor, hosted Workers, and MCP connections do work alongside teams. Recent shipping is almost entirely agent infrastructure — shareable Workers, an agent-focused iOS app, calendar and Outlook control, and admin guardrails for spend and audit.

◆ 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.
Notion
6.3PMCOMMS
Notion is turning its workspace into an orchestration layer for external AI agents.
◆ Current state
Notion has moved well past docs-and-wikis: the 3.5 Developer Platform and 3.6 release reposition it as an orchestration layer where external agents like Claude and Cursor, hosted Workers, and MCP connections do work alongside teams. Recent shipping is almost entirely agent infrastructure — shareable Workers, an agent-focused iOS app, calendar and Outlook control, and admin guardrails for spend and audit.
◆ Where it's heading
The direction is consistent: own the surface where humans and agents collaborate, then meter it. Workers move to credit-based billing on August 11, the MCP connector list keeps expanding, and each new capability — more file types, calendar, external-agent orchestration — widens what an agent can do inside Notion rather than adding features for people directly.
◆ Prediction
Expect the Workers-to-credits cutover to anchor a usage-based pricing push, with more first-party MCP connectors and deeper external-agent orchestration as the next beats.
