# October vs Google Antigravity

Your chosen harnesses, apps and people together, compared with Google’s agent development platform.

Checked 2026-11-02.

October is a shared workspace around the agents, applications and people involved in a project. Google Antigravity spans a desktop app, IDE, terminal CLI and agent SDK. Its app can run parallel local agents grouped into projects and workspaces, while browser workflows and verification artifacts help review results. It supports macOS, Windows and Linux; it is not just a single-agent editor. October brings independently chosen harnesses, applications and teammates into a shared canvas, with Agent Intercom for connected sessions. Antigravity provides an integrated agent development environment. Both support multiple agents, so compare how existing tools, people and live app context fit into your daily workflow.

## Choose October if
- You want independently chosen coding tools and human teammates on a shared canvas.
- You want connected sessions to exchange questions and results through Agent Intercom.
- You want to inspect live apps and agent work together, with canvas, Kanban and code views.

## Choose Google Antigravity if
- You want Google’s integrated agent development app, IDE and CLI.
- You want parallel local agents grouped into projects and workspaces.
- You want browser verification and artifacts inside the development workflow.

## Side by side

| What matters | October | Google Antigravity |
| --- | --- | --- |
| Main workflow | Coordinate coding agents, applications and people around a project. | Run agent-driven software development in an integrated platform. ([source](https://antigravity.google/)) |
| Working surface | A shared visual canvas, plus Kanban and code views. | Desktop app, IDE, command-line tool and SDK. ([source](https://antigravity.google/product)) |
| Where tasks run | Local and connected cloud work in the same workspace, subject to the service and plan. | Parallel local agents in the documented app workflow. ([source](https://antigravity.google/product)) |
| Agent coordination | Connected independent sessions exchange questions and results through Agent Intercom. | Agents grouped into projects and workspaces, with scheduled messages. ([source](https://antigravity.google/product)) |
| Tools and accounts | Bring supported coding harnesses with their existing provider accounts. | The platform’s agent tools, browser workflow and SDK. ([source](https://antigravity.google/product)) |
| Review and control | Inspect agent sessions, live app previews and results with your collaborators. | Review artifacts and browser-assisted verification within the platform. ([source](https://antigravity.google/product)) |

## What changes in the day-to-day workflow

October brings independently chosen harnesses, applications and teammates into a shared canvas, with Agent Intercom for connected sessions. Antigravity provides an integrated agent development environment. Both support multiple agents, so compare how existing tools, people and live app context fit into your daily workflow.

## Parallel agents are a starting point

Running several agents is now common across development environments. October’s focus is the workspace around them: place independent harnesses, browser previews and teammates together, then connect the sessions that need to exchange context. Antigravity offers its own app, IDE and CLI workflow. Try a real handoff involving the tools you already use before choosing which environment should surround the task.

## Questions

### Why use October if I already use Google Antigravity?

October puts independently chosen harnesses, browsers, live apps and teammates on one shared canvas. It is useful when your project spans more than one development tool.

### Does October require one harness for the whole project?

No. Bring the supported coding tools that fit the work and connect the sessions that need to communicate. Each tool still has its own setup, permissions and account requirements.

### What should I try first in October?

Have one supported agent implement a change and another review it. Inspect their findings beside the browser preview.
