| 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. | Bolt.new (by StackBlitz) lets you build full-stack web apps entirely in the browser — no local setup. Describe what you want, and Bolt generates, runs, and deploys a working app with real Node.js, npm, and a full development environment powered by Claude 3.5 Sonnet. |
