Antigravity CLI vs OpenAI Codex CLI — Feature Comparison
Quick answer: Antigravity CLI supports 15 of 18 tracked features; OpenAI Codex CLI supports 16 of 18. Matrix last updated September 18, 2026.
Verdict: Antigravity vs Codex CLI
Neither tool is universally better — the right choice depends on your workflow and the specific features that matter most to you. Both Antigravity CLI and OpenAI Codex CLI support 16 of the same 18 tracked features, putting them on near-identical functional footing, but they diverge in exactly the two areas that define your daily editing environment. Antigravity CLI supports multi-file editing, which is a meaningful advantage for developers tackling refactors or features that span multiple files simultaneously — a capability OpenAI Codex CLI currently lacks in this tracking. OpenAI Codex CLI, on the other hand, integrates with VS Code, making it the natural fit for developers whose primary environment is that editor rather than the terminal. On release cadence, Antigravity CLI has shipped a striking number of releases in a short window, suggesting an aggressive, fast-iterating development cycle that may mean rapid feature additions but also potentially more churn. OpenAI Codex CLI has a much larger total release history and a steady recent cadence, indicating a more mature, stabilized project. Developers who prioritize longevity, a proven track record, and VS Code integration will find Codex CLI compelling, while those who want cutting-edge multi-file capabilities and don't mind riding a fast-moving release train will gravitate toward Antigravity CLI.
Choose Antigravity CLI if: Choose Antigravity CLI if multi-file editing is a core part of your workflow — especially for large refactors — and you are comfortable with a rapidly iterating tool that ships updates at a high cadence.
Choose OpenAI Codex CLI if: Choose OpenAI Codex CLI if you work primarily inside VS Code and want a more established tool with a long release history and a stable, steady development pace.
Key differences
