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.

What is Rootly?

Rootly is grinding an AI-native incident platform out feature-by-feature, weekly

Rootly ships a genuine weekly changelog for its incident-response platform, spanning on-call, alerting, retrospectives, mobile, and an embedded AI agent. Recent releases lowered onboarding friction (one command to a paging test), tightened responder ergonomics (on-call widget, 24-hour time, customizable Alerts table), and pushed AI deeper into workflows via retrospective AI-blocks and the Rootly Agent now living in the web app.

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.

Rootly is grinding an AI-native incident platform out feature-by-feature, weekly

◆ Current state

Rootly ships a genuine weekly changelog for its incident-response platform, spanning on-call, alerting, retrospectives, mobile, and an embedded AI agent. Recent releases lowered onboarding friction (one command to a paging test), tightened responder ergonomics (on-call widget, 24-hour time, customizable Alerts table), and pushed AI deeper into workflows via retrospective AI-blocks and the Rootly Agent now living in the web app.

◆ Where it's heading

The arc is toward an agent-assisted incident workflow where the Rootly Agent is available on every incident and AI drafts the retrospective from live data, Slack, and call transcripts — always with sources in view. Around that, steady enterprise plumbing (Cortex catalog sync, Intune mobile policies, global on-call pay) broadens fit for larger orgs.

◆ Prediction

Expect the Rootly Agent to keep expanding into more surfaces and phases of the incident lifecycle, and more enterprise integrations (catalog, MDM, identity). The 'every prompt and source in view' framing suggests explainability will remain a deliberate counter to black-box AI.
