“A cloud console shows your running remotes, apps and middleware, in case the one thing missing from your editor was an on-call dashboard.”
Spec by spec
| Spec | Google Antigravity | JoyCode |
|---|---|---|
| Architecture | ||
| Category | AI-native IDE | AI-native IDE |
| Runs | local | local, cloud |
| Platforms | macos, linux, windows | macos, windows |
| Context window | not documented | not documented |
| Protocols | ||
| MCP client | Yes | Yes |
| MCP server | No | No |
| Capabilities | ||
| Runs terminal commands | Yes | NoAgents are configured with built-in tools and MCP servers, but the published docs do not name a shell or terminal tool. |
| Multi-file edits | Yes | YesImplied by the agent and built-in tool model and the spec-driven end-to-end claim; the three published doc pages do not state it in those words. |
| Git operations | Yes | No |
| Browser control | YesA first-party browser subagent drives Chrome from a separate profile with allowlist/denylist controls (https://antigravity.google/docs/ide/browser/); IDE-side only, not in the agy CLI. | No |
| Sandboxed execution | YesOS-level isolation rather than containers: "no virtual machines or Docker images to manage" - Linux uses kernel namespaces to isolate the filesystem, hide host processes and cut networking; macOS uses sandbox-exec with Seatbelt (SBPL) profiles. | No |
| Multi-agent orchestration | Yes | YesA team defines multiple named agents with their own prompts, tools and MCP servers. |
| Headless / CI mode | Yes | No |
| Models | ||
| Backbone | Gemini 3.1 Pro, Gemini 3.8 Flash, Claude Sonnet 4.6, Claude Opus 4.6, gpt-oss-120b | bundled Chinese models, custom client-side models |
| Bring your own model | YesSetting `modelProvider: "gemini"` in ~/.gemini/antigravity-cli/settings.json plus a GEMINI_API_KEY runs the CLI on your own key and billing instead of a signed-in Google account, and a model selector picks between Gemini, Claude and gpt-oss models in the IDE. | Yes |
| Local models | YesGOOGLE_GEMINI_BASE_URL sends model requests to any Gemini-compatible endpoint, so a self-hosted shim works as a mechanism; no Ollama or LM Studio integration is documented. | No |

Which one would each critic pick
| Critic | Google Antigravity | JoyCode | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.0 | 6.3 | Google Antigravity — Pick Antigravity if you want several agents running at once with a browser checking their work; pick Cursor if you want one agent that edits well and stays out of the way. |
| El Crítico | 6.3 | 5.5 | Google Antigravity — Agents drive your editor, terminal and a live Chrome with no container between them and your machine; the only isolation on offer is a git worktree. |
| El Profesor | 6.3 | 6.5 | JoyCode — Rules resolve in a stated order, team then project then user, which makes precedence a specification rather than an emergent property of whichever file loaded last. |
| La Inversora | 7.3 | 6.3 | Google Antigravity — Google is bundling the IDE into Google AI Pro and Ultra subscriptions, distribution no startup on this board can match and a roadmap no buyer controls. |
| La Jefa | 5.3 | 6.0 | JoyCode — Enterprise is CNY 79 per user a month, so sixty seats is a line I can forecast, and single sign-on sits in the custom edition above it rather than in the one I would buy. |
| El Hacker | 4.0 | 5.5 | JoyCode — Closed source, but the server configuration is a real mcpServers JSON block with documented npx and uvx invocations per operating system, and custom models attach on the client. |
