| Description | Cobalt is a cloud-first harness for running coding agents in isolated cloud environments, one dedicated computer per task, with the repository, services, branch, and state kept separate. It lets teams choose among supported agents like Codex, Gemini, and Claude Code, run multiple tasks in parallel, automate recurring work with scheduled Loops, and keep humans in the loop to watch, steer, review, and ship via pull requests. Each task keeps its prompt, runtime, live preview, diff, and delivery attached in one place. | v0 by Vercel is an AI-powered UI generation tool that turns natural language prompts into beautiful, production-ready React components with Tailwind CSS and shadcn/ui.
