Google AntiGravity vs Google Jules

IDE vs. agent. AntiGravity is an application you open and code inside. Jules is a service you assign tasks to. This is the fundamental split. Everything else flows from it.

Local vs. cloud. AntiGravity runs on your machine. Your code stays local, your agents execute locally, and you control the environment. Jules runs in Google's cloud. It clones your repo into a VM, does its work there, and pushes changes back through GitHub. You never touch its execution environment.

Interactive vs. async. When you use AntiGravity, you're in a conversation with the AI. You type, it suggests, you accept or reject, you iterate. Jules is fire-and-forget. Assign a task, close the tab, come back later to review the PR. This makes Jules genuinely useful for batching: send it 10 bug fixes before lunch, review the PRs after.

Model breadth. AntiGravity gives you Gemini 3.1 Pro, Gemini 3 Flash, Claude Sonnet 4.6, Claude Opus 4.6, and GPT-OSS 120B. You pick the model per task. Jules only runs Gemini models: Flash on free, Pro on paid. If you need Claude or GPT for a specific coding task, that's an AntiGravity thing.

Autocomplete. AntiGravity has unlimited tab completions. Jules has no autocomplete because it's not an IDE. There's nothing to complete. You write a task description in English, not code.

GitHub integration depth. Both connect to GitHub, but differently. AntiGravity has standard IDE git integration: commit, push, pull, branch. Jules natively creates branches and pull requests as its output format. GitHub isn't just connected; it's the entire delivery mechanism.

Use case in one sentence. AntiGravity: "I'm coding right now and want AI help." Jules: "I have 20 bugs to fix, handle it."

Google AntiGravity and Google Jules are both Google products, both powered by Gemini models, but they solve fundamentally different problems. If you're confused about which one to use, you're not alone. Google hasn't done a great job explaining how they fit together.

AntiGravity is a desktop IDE. It's a VS Code fork with AI baked into every surface: tab completions, inline chat, multi-agent orchestration, a built-in browser for testing. You install it, open your project, and code inside it. The AI assists while you work. It supports Gemini, Claude, and GPT models, so you can pick the right model for the task. Think of it as your workstation with AI superpowers.

Jules is something else entirely. It's a cloud agent. You don't write code in Jules. You give it a task ("fix the auth bug in this repo", "add unit tests to the payments module"), and it spins up a cloud VM, clones your GitHub repo, works on it autonomously, and comes back with a pull request. You review the PR, merge it, done. Jules doesn't have an editor. It doesn't have autocomplete. It's not a place where you sit and work. It's a thing you delegate to.

The mental model that makes this click: AntiGravity is your AI-enhanced workstation. Jules is your AI employee who works while you sleep. Same company, same billing, totally different roles.

Both tools are free to start, and both upgrade through the same Google AI subscription tiers. But the free tiers feel very different because of how each tool measures usage.

AntiGravity free gives you unlimited tab completions, access to every supported model, and generous weekly rate limits that reset automatically. For a lot of developers, this covers a full day of coding without hitting any wall. You can also buy $25 credit packs (2,500 AI credits) for burst usage when you need more. Google AI Pro at $20/month raises the weekly limits. Ultra at $250/month removes most caps.

Jules free gives you 15 to 20 tasks per day with 3 running concurrently, using the Gemini 3 Flash model. That's enough to test the product and handle a handful of maintenance tasks daily. Pro at $20/month bumps you to roughly 100 tasks per day with 15 concurrent, and unlocks Gemini 3.1 Pro. For teams running Jules at scale, Ultra increases those limits further.

For daily interactive coding, AntiGravity's free tier is more generous. You'll get more done before hitting limits. For batch task automation, Jules Pro's task count is the bottleneck that determines value. The $20/month Pro tier covers both tools, so if you use both, you're not paying twice.

If you're actively coding and want AI in your IDE, AntiGravity. It's where you sit and work. Tab completions, inline chat, agent orchestration, model switching, all available while you write code. If you already use VS Code, the transition is painless.

If you have a backlog of maintenance tasks and want to delegate, Jules. Bug fixes, test coverage, dependency updates, code migrations. Write up the tasks, send them to Jules, review the PRs when they're ready. This is where Jules actually saves you time: it works in parallel on multiple tasks while you focus on something else.

If you want both, use both. They're complementary by design. Code your main feature work in AntiGravity, delegate the routine stuff to Jules. Both tools bill through Google AI subscriptions, so a single Pro plan covers increased limits on both.

If you're choosing between them for a free tier, AntiGravity gives more value for daily coding. You'll use tab completions and chat constantly. Jules gives more value for async work: if you have specific tasks to offload, even 15 free tasks per day is meaningful.
