# Antigravity alternatives, or Antigravity beside Claude Code and Codex

*Updated 6 November 2026. Canonical: https://zoltbot.ai/alternatives/antigravity*

**Short answer:** The alternatives people weigh against Google Antigravity are Claude Code, Codex and Cursor. You can also keep Antigravity and use them beside it. Zoltbot is a free, open-source Mac app that runs Antigravity, Claude Code, Codex and Cursor through their own CLIs, and each task can get its own Git worktree. Stay with Antigravity alone if you work on Windows or Linux, or if its own App already runs all the agents you need.

## Antigravity and the alternatives side by side

*Antigravity, Claude Code, Codex and Cursor, checked 6 November 2026*

|  | Antigravity | Claude Code | Codex | Cursor |
| --- | --- | --- | --- | --- |
| Made by | Google | Anthropic | OpenAI | Anysphere |
| Where it runs | An App, a CLI and an IDE on macOS, Windows, Linux and Googlebook | Terminal, IDE extensions, a desktop app and the web | The ChatGPT desktop app, a CLI, an IDE extension, the web and iOS | An editor with an Agents Window, a CLI and cloud agents |
| Cheapest way in | Individual plan at $0 with weekly rate limits; Google AI Pro and Ultra raise them | Claude Pro, $20 a month | Limited use on ChatGPT Free and Go; Plus at $20 for the CLI | Free with limited agent requests; Plus $8 runs Grok models only |
| Several agents at once | The App runs multiple local agents in parallel; the CLI runs background subagents | Agent view, subagents and agent teams | Several chats, cloud tasks and scheduled tasks | Parallel agents in the Agents Window, plus cloud agents |
| A separate checkout per task | Not stated on Antigravity's site | Yes, `claude --worktree` | Yes, the Worktree option in the desktop app | Yes, worktrees in the Agents Window |
| Organizing work | Projects that span several folders, and scheduled tasks | Sessions tied to a project folder | Projects in the desktop app | Agents across several repositories in one Agents Window |
| Past chats | Grouped into Projects in the App | `claude --resume` | `codex resume` | `agent ls`, then resume |
| Runs in Zoltbot beside the others | Yes, through `agy acp`, its official ACP mode | Yes, through the `claude` CLI | Yes, through the `codex` CLI | Yes, through the Cursor CLI's ACP mode |

The last row is where Zoltbot fits. It is a Mac app that runs these four agents: you pick which one takes each chat or task, and they all show up in one project tree and one review queue.

## Where each alternative is stronger

### Claude Code

Claude Code has many built-in ways to run sessions in parallel from a terminal: subagents, agent view, agent teams and `claude --worktree`. Every worker is a Claude session, so it suits you if Claude is the model you trust for most of your code. It needs a paid Claude plan, starting with Pro at $20 a month.

### Codex

Codex is easy to try: ChatGPT Free and Go include limited use, and Plus at $20 covers the CLI. The ChatGPT desktop app mixes local worktree chats with cloud tasks, and the mobile app can approve and review tasks while you're away from your desk.

### Cursor

Cursor keeps an editor at the center, with an Agents Window for parallel agents in worktrees and cloud agents that run in isolated VMs without your machine online. Its plans changed recently: Plus at $8 runs Grok models only, and Claude and other third-party models are billed at API list price on Premium and above.

### Antigravity itself

Antigravity has a $0 Individual plan, and its App already gives you a command center for parallel local agents, projects across folders and scheduled tasks. If the reason you're looking around is a single feature, check the [Antigravity changelog](https://antigravity.google/docs/changelog) first.

## Keep Antigravity and add the others

Comparisons tend to treat these tools as rivals, but nothing stops you from using more than one. Each vendor's plan has its own usage limits, and different models get different jobs right. The hard part is keeping track of which agent is doing what, in which folder, on which branch.

*Figure: One Zoltbot project with three tasks on three agents, each in its own Git worktree, all feeding one review queue.*

A Zoltbot project called Shop holds three tasks. The first runs on Antigravity in a worktree on the branch task/search. The second runs on Claude Code on task/auth. The third runs on Codex on task/billing. Each agent runs through its own CLI and login. All three finished tasks go to one review queue, where you request changes or integrate each one into main. Ports and the dev database stay shared between the worktrees.

### You like Antigravity but want Claude or Codex for some tasks

Give each sub-project or chat the agent that suits it. Antigravity can take one task while Claude Code and Codex take others, on the plans and logins you already have. Zoltbot never asks for your password or copies your credentials.

### You want each task on its own branch

When you create a task, choose Separate Git worktree and a base branch. The task runs on its own checkout beside your other tasks, so two agents never edit the same files. Tasks that share a folder run one at a time with a visible reason. Ports and databases are still shared, so two dev servers on one port will still collide.

### You want one place to review results

Finished tasks from every agent land in the same review queue. You read the outcome, then request changes (another revision in the same conversation) or integrate it into your branch. Integration is fast-forward only today.

### You want your chats to stay with Antigravity

Zoltbot doesn't keep a private copy of your conversations. Antigravity chats stay native Antigravity sessions, and Zoltbot reopens them through Antigravity's own interface. Two limits: importing past Antigravity chats isn't supported (import covers Claude Code and Codex), and we haven't verified whether chats started in Zoltbot appear in Google's Antigravity App.

## When to stay with Antigravity alone

Stay with Antigravity on its own if you work on Windows, Linux or a Googlebook, since Zoltbot runs only on macOS today. Stay if you use one agent and the Antigravity App's projects, parallel agents and scheduled tasks already cover your day, because adding a second app gives you nothing new. And stay if you rely on the IDE's tab completions and inline commands, which Zoltbot doesn't replace: it runs agents, and you keep whatever editor you like.

## How to run Antigravity in Zoltbot

1. Install the Antigravity CLI with Google's installer (below). It puts `agy` in `~/.local/bin`. Run `agy --version` to check it.
2. Sign in once by running `agy` in a terminal. It opens your browser for your Google account. To use a Gemini API key instead, set `modelProvider` to `gemini` in Antigravity's CLI settings and export `GEMINI_API_KEY`.
3. Download Zoltbot for macOS, open Doctor and choose Scan coding tools. Zoltbot looks on your shell's PATH and in `~/.local/bin`, finds `agy` and checks its version. The tested version is 1.4.12.
4. Create a profile and pick Antigravity as the provider. Zoltbot starts `agy acp --process-per-session` and reuses your cached sign-in. If you aren't signed in, the Context panel shows the command to run.
5. Create a task, choose Separate Git worktree and a base branch, and send it to the Antigravity profile. Give other tasks Claude Code, Codex or Cursor profiles.
6. When a task finishes, review the outcome, then request changes or integrate it.

```sh
curl -fsSL https://antigravity.google/cli/install.sh | bash
agy --version
```

> Antigravity starts in workspace-write mode and asks before acting. A read-only profile only works when Antigravity offers a safe mode, and fails closed when it doesn't. Zoltbot shows usage and cost only when Antigravity reports them.

## Questions

### Is there a free alternative to Antigravity?

Yes. Codex has limited use on ChatGPT Free, and Cursor has a free tier with limited agent requests. Antigravity's own Individual plan is also $0, so price alone is rarely a reason to switch.

### Is there an open-source Antigravity alternative?

Yes. Zoltbot is open source and free for individuals, but it runs agents rather than replacing one: it can run Antigravity itself, next to Claude Code, Codex and Cursor.

### Is Antigravity better than Claude Code?

Neither wins every task. Antigravity starts free and comes with its own App and IDE; Claude Code has more ways to coordinate many sessions from the terminal. Running both on the same real task is the quickest way to decide.

### Can I use Antigravity and Claude Code together?

Yes. In Zoltbot, one task can run on Antigravity and another on Claude Code, each in its own Git worktree, with both results in one review queue.

### Does Zoltbot work with Antigravity on Windows or Linux?

No. Zoltbot runs on macOS today, with Windows and Linux planned. Antigravity itself runs on all three.

### Will Zoltbot import my past Antigravity chats?

No. Chat import covers Claude Code and Codex. New Antigravity chats you start in Zoltbot stay native Antigravity sessions.
