Mattermost vs Notion
Side-by-side trajectory, velocity, and editorial themes.
v11.7 ships rearchitected AI agents and granular ABAC as Mattermost leans hard into regulated buyers.
Mattermost is now openly positioning as a collaboration platform for defense, intelligence, and critical infrastructure rather than a general-purpose team-chat alternative. The v11.7 release pairs Attribute-Based Access Control for Team Admins with a rearchitected Agents v2.0 layer that supports custom AI prompts and user-created agents, signaling that the AI roadmap will run on top of strict access governance rather than alongside it. Editorial output in May is overwhelmingly about sovereignty, coalition operations, and AI governance — the company is telling regulated buyers what to ask vendors during procurement.
The product is bifurcating from horizontal team chat into a sovereignty-and-governance-first platform aimed at procurement evaluations in defense and regulated finance. Each major release now ships more granular control surfaces (ABAC, coordinated ESR security cadence) underneath user-facing features (AI agents, custom prompts), which is consistent with a market where features only matter if they can pass a compliance review. Expect future releases to keep coupling AI capability to governance primitives rather than shipping AI features on their own.
The next minor release likely extends ABAC scope beyond Team Admins (channel-level or integration-level enforcement) and tightens the audit trail around user-created agents, since both are the natural follow-ons for a customer base that procures on control granularity. A coalition or cross-domain feature announcement is also plausible given how heavily April-May messaging leaned on multi-nation operational use cases.
Notion turns itself into the orchestration layer where other agents run.
Notion has shipped a full developer platform — Workers as a hosted runtime, External Agents API for Claude/Codex/Decagon, a CLI, inbound webhooks, and an Agent SDK. The Custom Agents beta has produced more than a million agents in two months, and the latest releases are about turning that surge into something enterprises will actually deploy: per-agent credit limits, workspace caps, admin dashboards, and a Library directory. Doc editing has become the visible surface; the engine being built underneath is agent and data plumbing.
The trajectory is from doc-and-database app to connective tissue between agents, SaaS APIs, and team workflows. Each recent release pushes in the same direction — agents become more discoverable (Directory), more reviewable before they act (Plan Mode), more governable at scale (admin controls), and more capable of reaching outside Notion (Agent SDK, webhooks). The strategic bet is that whoever owns the orchestration substrate matters more than whoever ships the smartest model.
Expect Workers to convert from free-beta to credit-metered on August 11, 2026, with pricing pressure landing on agent-SaaS startups whose value is mostly API stitching. The External Agents API and Agent SDK should move from waitlist to GA next, alongside deeper Slack/MS Teams surfaces where Notion agents run without users ever opening Notion.
