What is Knock?
Knock deepens its authoring, environment, and security surfaces week over week.
Knock is notification infrastructure with a dashboard that keeps absorbing more of the messaging workflow. Recent releases span the template editor, git-style branch management, dashboard security, organization tools, and warehouse data sync — a broad, steady grind rather than a single focus.
What is Cosmic?
Cosmic is rebuilding a headless CMS around autonomous, tool-using content agents.
Cosmic is a headless CMS that has pivoted hard toward agents: recent releases give Team Agents goals, computer-use, and the ability to create and edit content directly, backed by semantic (RAG) search over a workspace's objects. It is also consolidating a sprawl of AI entry points into three surfaces and keeping current with frontier models. The content-management fundamentals — rich text, assignments, capacity add-ons — still ship alongside.
Knock vs Cosmic: editorial side-by-side
Knock
5.0INFRA · APIS
Knock deepens its authoring, environment, and security surfaces week over week.
◆ Current state
Knock is notification infrastructure with a dashboard that keeps absorbing more of the messaging workflow. Recent releases span the template editor, git-style branch management, dashboard security, organization tools, and warehouse data sync — a broad, steady grind rather than a single focus.
◆ Where it's heading
The arc is making the dashboard a self-serve control center that non-engineers can operate safely. A Notion-style template editor and hosted preference center move authoring away from code; branch rebasing brings a git-like change model to environments; passkeys and MFA raise account security; saved views, tags, schema management, and warehouse event sync improve organization and observability. Each release is a solid, non-directional improvement.
◆ Prediction
Expect the authoring and environment-management surfaces to keep converging — the redesigned editor and branch workflow point toward a more code-like but non-engineer-friendly change process. Continued investment in security and warehouse observability suggests a push upmarket toward larger teams.
Cosmic
5.0INFRA · APIS
Cosmic is rebuilding a headless CMS around autonomous, tool-using content agents.
◆ Current state
Cosmic is a headless CMS that has pivoted hard toward agents: recent releases give Team Agents goals, computer-use, and the ability to create and edit content directly, backed by semantic (RAG) search over a workspace's objects. It is also consolidating a sprawl of AI entry points into three surfaces and keeping current with frontier models. The content-management fundamentals — rich text, assignments, capacity add-ons — still ship alongside.
◆ Where it's heading
The arc is unmistakable: from AI-assisted editing toward agents that do content work on their own. Computer-use lets an agent drive a real browser, goals let it run multi-step tasks, and RAG search grounds it in the customer's own content. Cosmic is betting the CMS becomes an operator, not just a store.
◆ Prediction
Expect the three-surface consolidation to continue, with more agent autonomy and connector reach; model additions like Kimi K3 will keep arriving as routine roster updates rather than milestones.
