Comparisons

Codex is the company choice, since it comes inside ChatGPT Business with SAML SSO, while Jules comes inside Google AI plans for personal accounts only. Jules suits individual developers on its free tier. Each takes a delegated task in a cloud environment built from GitHub repositories and returns changes to review.

Devin is the team purchase. It sells Teams seats with admin controls, works with GitLab, Bitbucket, and Azure DevOps, and starts work from Slack and Linear. Jules is the individual pick, with a free tier and Google AI plan limits and no team plan.
