| 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. | Aider is the open-source AI pair programmer that works in your terminal with your existing codebase. It edits files and commits to git automatically, supports 100+ LLMs, and consistently tops AI coding benchmarks — the choice of developers who want full control. |
