Antigravity CLI vs Kiro CLI — Feature Comparison
Quick answer: Antigravity CLI supports 15 of 18 tracked features; Kiro CLI supports 9 of 18. Matrix last updated July 19, 2026.
Verdict: Antigravity vs Kiro
Antigravity CLI is the better choice for most developers, but Kiro CLI has a legitimate edge in multi-file workflows. Antigravity CLI supports 14 of 18 tracked features compared to Kiro CLI's 10, and the qualitative nature of those additional features matters: Streaming Output, Diff View, Undo/Redo, Background Tasks, and a Web UI collectively paint a picture of a tool built for interactive, iterative work where visibility and control over changes are paramount. If you want to see edits as they happen, review diffs before committing, or recover from mistakes without leaving your workflow, Antigravity CLI is clearly more equipped. Kiro CLI, on the other hand, counters with Multi-file Editing support — a meaningful capability that Antigravity CLI lacks — making it the stronger pick when a task inherently spans several files at once, such as refactoring across a module or scaffolding a new feature with coordinated changes. Kiro CLI also shows a higher total release count and a slightly faster recent cadence, suggesting an active project with momentum that may close the feature gap over time. Neither tool is a wrong choice: Antigravity CLI wins on present-day feature breadth and developer ergonomics; Kiro CLI wins on cross-file coordination and release velocity. The decision ultimately hinges on whether your daily work demands rich single-session interactivity or broad, simultaneous multi-file manipulation.
Choose Antigravity CLI if: Choose Antigravity CLI if your workflow is interactive and iterative — you want streaming feedback, diffing before you commit, undo safety, and optionally a Web UI to complement your terminal work.
Choose Kiro CLI if: Choose Kiro CLI if your tasks routinely require coordinated edits across multiple files at once, or if you want a tool with a strong and accelerating release cadence that signals rapid future improvement.
