What is Depot?
Depot is expanding from build acceleration into a full dev-infra platform — its own compute metal and now its own git hosting.
Depot is moving fast beyond its build-cache roots. In a matter of weeks it launched Depot Metal (its own bare-metal compute and storage tier, claiming up to 50% faster CI), opened Depot Code (a diskless, S3-backed git hosting service) in private beta, extended Sherlock AI analysis to every workflow and job, and broadened CI plumbing with Tailscale networking, GitLab OIDC, and historical-timing test splitting. The surface is widening from 'make builds fast' to 'run the whole CI and source stack.'
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.

Depot

Depot is expanding from build acceleration into a full dev-infra platform — its own compute metal and now its own git hosting.
◆ Current state
Depot is moving fast beyond its build-cache roots. In a matter of weeks it launched Depot Metal (its own bare-metal compute and storage tier, claiming up to 50% faster CI), opened Depot Code (a diskless, S3-backed git hosting service) in private beta, extended Sherlock AI analysis to every workflow and job, and broadened CI plumbing with Tailscale networking, GitLab OIDC, and historical-timing test splitting. The surface is widening from 'make builds fast' to 'run the whole CI and source stack.'
◆ Where it's heading
The trajectory is vertical integration: Depot is taking ownership of each layer beneath CI — compute (Metal), networking (Tailscale, OIDC), test intelligence (splitting, Sherlock), and now source control (Code). Owning git hosting is the boldest step, positioning Depot to plug source, compute, and CI into one tightly coupled system rather than accelerating someone else's stack.
◆ Prediction
Expect Depot Code to progress from private beta toward general availability with tighter Depot CI integration, and Sherlock's AI analysis to expand from diagnosis toward more proactive optimization suggestions.
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.
