OpenAI Codex
Editorial take
Codex is what you buy when the factory is allowed to standardize on OpenAI the way Claude Code standardizes on Anthropic. The CLI is real and CI-usable. It is not model-agnostic and not open source. Treat cloud tasks as OpenAI-hosted computers, not as a box you inspect. Compare it to Claude Code, not to Aider.
Claude Code
Editorial take
Claude Code is the strongest single-harness execution tool in this seed set if your factory is allowed to standardize on Anthropic. The Unix posture — pipe logs in, run headless in CI, hook every file edit — is why teams build factories around it instead of an IDE. Locked models are the trade. Bedrock, Vertex, Foundry, and the Anthropic API change where Claude runs, not whether you can swap in another lab's model. Self-hosted environments exist in public beta on Team and Enterprise for cloud sessions; local CLI work already runs on the developer's machine. There is no public source repository for the product.
