Lantern vs Google Antigravity

A helper beside existing apps, compared with a dedicated agent development environment.

Checked 2026-11-02 · 5 official sources · Read the sources

Lantern is a small assistant beside your current application, with screen questions, Show me guidance and an inbox for supported coding agents. 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. Lantern begins with quick questions about the application on screen, next-step guidance and an inbox for supported coding-agent sessions. Antigravity begins with a software-development workspace. Keeping an everyday helper nearby is a different decision from choosing the environment in which an agent builds software.

Choose Lantern if

You want to ask about the app in front of you without organizing another workspace.
You want visual next-step guidance through Show me.
You want questions from supported existing coding sessions collected in one nearby helper.

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.

Agent coordination	Collect questions and route replies for documented supported coding sessions.	Agents grouped into projects and workspaces, with scheduled messages. [2]
Tools and accounts	Use the Lantern account and its supported agent integrations; provider usage remains separate where applicable.	The platform’s agent tools, browser workflow and SDK. [2]
Review and control	Follow the next step yourself or inspect a helper’s result and answer agent requests.	Review artifacts and browser-assisted verification within the platform. [2]

What kind of help do you need?

Lantern begins with quick questions about the application on screen, next-step guidance and an inbox for supported coding-agent sessions. Antigravity begins with a software-development workspace. Keeping an everyday helper nearby is a different decision from choosing the environment in which an agent builds software.

Choose the helper and the development environment separately

A question about an application does not always need a new coding workspace. Lantern can keep that interaction close to the current screen while your coding tasks remain in their existing tools. Antigravity is a development platform to evaluate for those coding tasks themselves. This comparison treats those roles separately rather than claiming that one lacks agents or computer context.

Questions about Lantern.

What does Lantern add if I already use Google Antigravity?

Lantern provides help beside your existing applications and attention to supported coding sessions. You can choose that companion separately from the development environment you use to build software.

Can Lantern control every tool shown in its comparisons?

No. These pages explain product choices, not a list of guaranteed integrations. Check Lantern’s documented support for the agent, terminal, platform and action you want to use.

How should I try Lantern with my current setup?

Keep your development environment in place. Try Lantern on an app question, then test agent attention only with a documented supported session.
