Best Terminal AI Coding Agent: A Measured Three-Way
Feature tables have converged, so we measured lock-in instead — which configuration surfaces survive a move between Claude Code, Codex CLI and Antigravity CLI.

Feature tables have converged, so we measured lock-in instead — which configuration surfaces survive a move between Claude Code, Codex CLI and Antigravity CLI.

Both are terminal agents and the feature lists have converged. The decision that costs you a day is configuration portability — so we measured it on a real repo.

The three converged at $20/month for individuals and diverged completely at team scale. Windsurf is now Devin Desktop, and the team pricing is where the real difference is.

Copilot has a terminal agent with plan mode now, so the old framing is dead. The real split is where the agent runs, how it bills, and which models it can reach.

The workflow difference that actually matters when picking between them — not a feature checklist, since both ship the same feature list within a quarter of each other.
