An in-depth comparison of Google Antigravity and Kilo Code across output quality, autonomy, reliability, speed, value, and ease of use. Vote for your favorite.
Pick a winner in each category — you can change your vote anytime.
Choose Google Antigravity if you are developers who want to try the most agentic IDE experience available today. Choose Kilo Code if you are vS Code users who want an open-source AI coding assistant.
Editorially this matchup is a dead heat: each agent leads in 2 of our six categories. On price, Google Antigravity runs free public preview and is proprietary; Kilo Code runs free / pro via standard compute and is open source.
Antigravity is Google's agentic development platform, launched alongside Gemini 3: a VS Code-style IDE where an agent manager dispatches agents that work across the editor, terminal, and a Chrome browser they control — producing verifiable artifacts (plans, screenshots, browser recordings) as they go. The free public preview and Gemini 3 Pro quality made it an instant heavyweight, but it's still early: capacity limits, preview rough edges, and early prompt-injection concerns around the browser-control surface mean production teams should keep a human on the loop.
Kilo Code is an open-source VS Code extension that brings powerful AI coding assistance directly into your editor. It supports multi-file editing, intelligent refactoring, and context-aware code generation. Works with any OpenAI-compatible API.
Both work with any OpenAI-compatible provider. Point the base URL at Standard Compute and get unlimited frontier-model compute from $9/mo flat — no per-token billing, no 429 rate limits.
Whichever AI agent you choose, Standard Compute gives you unlimited LLM compute at one flat monthly price. No rate limits, no per-token billing.
