So you’ve been using Antigravity, Google’s agentic development platform, and now version 2.0 is rolling out with a fresh wave of upgrades. If you’re wondering how to update Antigravity 2.0 without breaking your workflow, losing your agents, or stumbling through a confusing setup — you’re in the right spot.
Honestly, most update guides skip the practical bits. They tell you what to click but never why an update fails or what to do when something goes sideways. This guide does both. By the end, you’ll know exactly how to install the latest version, migrate your existing projects, and troubleshoot the few hiccups people actually run into.
Let’s get into it.
Last Updated: May 2026 — Always verify the latest version directly on antigravity.google/product/antigravity-2, since Google ships updates frequently.
What Is Antigravity 2.0 and Why the Update Matters
Antigravity is Google’s agentic IDE — think of it as a coding environment where AI agents can plan, write, and execute tasks across your editor, terminal, and browser all at once. Version 2.0 isn’t a small patch. It’s a structural leap forward.
The 2.0 release brings deeper Gemini integration, faster multi-agent orchestration, smarter context handling across long sessions, and a redesigned task surface that lets you watch agents work in real time. If you’ve been holding off on updating, you’re leaving real productivity on the table.
And here’s the thing — older versions of Antigravity will keep working, but they won’t get the newest model routing, security patches, or the improved Artifacts panel. Staying current isn’t optional if you care about performance.
Who Should Update Right Now?
Not everyone needs to rush. But most users should. Here’s a quick breakdown:
- Solo developers building side projects — yes, update for the speed boost
- Team leads managing shared agent workflows — yes, the orchestration improvements alone are worth it
- Enterprise users on managed builds — check with your admin first
- Anyone on a legacy 1.x setup with custom plugins — review compatibility before pulling the trigger
If you fall into that last bucket, slow down for a moment. We’ll cover plugin migration further down.
Before You Update: The Pre-Flight Checklist
Most update problems aren’t caused by the update itself. They’re caused by skipping prep. Spend five minutes here and you’ll save yourself an hour later.
1. Check Your Current Version
Open Antigravity. Click the gear icon in the bottom-left, then About Antigravity. You’ll see your current build number. Anything below 2.0.x means you’re due for the full upgrade. If you’re already on a 2.0 minor release (like 2.0.3), the update process is faster and less invasive.
2. Back Up Your Workspaces
This is the step everyone wants to skip — and the one that bites hardest when it goes wrong.
Antigravity stores workspace configs, agent histories, and custom prompts locally. Before updating, export your settings:
- Go to File → Export Workspace Settings
- Save the
.agwsfile somewhere safe (cloud drive, external folder, anywhere off your active machine) - If you have custom agents, export those separately under Agents → Manage → Export All
Truth be told, the official update process preserves most of this automatically. But “most” isn’t “all,” and the one time it fails is the time you didn’t back up.
3. Confirm System Requirements
Antigravity 2.0 raised the floor slightly. Make sure your machine clears these specs:
| Component | Minimum | Recommended |
|---|---|---|
| OS | macOS 12, Windows 10, Ubuntu 20.04 | Latest stable releases |
| RAM | 8 GB | 16 GB or more |
| Storage | 4 GB free | 10 GB free |
| Network | Stable broadband | Wired or 5GHz Wi-Fi |
| Google Account | Required | Workspace account for team features |
If you’re under the minimum, the installer will warn you — but you may not get the full performance benefits.
4. Close Active Agent Sessions
Don’t update while agents are mid-task. Pause or stop every running session, then let pending file writes finish. Yanking an update underneath a working agent is the fastest way to corrupt a workspace.
How to Update Antigravity 2.0 — Step-by-Step
Here’s the part you came for. There are three ways to update, depending on how you installed Antigravity in the first place.
Method 1: Auto-Update (Easiest, Recommended for Most Users)
This is the default for individual users on the consumer build.
- Launch Antigravity as you normally would
- Look for the update notification in the top-right corner — it appears as a small badge on the bell icon when a new version is available
- Click Update Now
- Antigravity downloads the new build in the background while you keep working
- When the download finishes, you’ll see a Restart to Apply banner
- Save any open files, then click restart
- Antigravity relaunches in version 2.0
That’s it. The whole thing usually takes 3–7 minutes on a decent connection.
Method 2: Manual Download (For Locked-Down Environments)
If your firewall or IT policy blocks in-app updates, you’ll need to grab the installer directly.
- Head to the official Antigravity download page on antigravity.google
- Sign in with the same Google account you use inside Antigravity
- Pick your operating system — macOS (Universal or Apple Silicon), Windows (x64), or Linux (.deb / .rpm / AppImage)
- Download the installer
- Close Antigravity completely (check your system tray — it sometimes stays running in the background)
- Run the installer
- Follow the prompts — on Mac, drag to Applications; on Windows, walk through the .msi wizard; on Linux, use
sudo dpkg -iorsudo rpm -i - Launch Antigravity and sign back in
Your settings, workspaces, and agent history should restore automatically. If they don’t, that’s where your backup .agws file from earlier earns its keep.
Method 3: Command-Line Update (For Power Users)
If you installed via package manager, you can update through the terminal.
macOS (Homebrew):
brew update
brew upgrade antigravity
Linux (apt):
sudo apt update
sudo apt install --only-upgrade antigravity
Linux (snap):
sudo snap refresh antigravity
After the upgrade, restart Antigravity. The new version takes over from the same install path, so no extra cleanup is needed.
How to Migrate Your Workspaces and Agents
Most of the update friction lives here, not in the install itself.
Workspace Migration
Antigravity 2.0 reads 1.x workspace files natively. When you first launch a workspace after updating, you’ll see a one-time prompt: “Upgrade workspace format?” Click yes.
The upgrade re-indexes your project files, refreshes the agent context graph, and converts old task definitions to the new schema. On a medium-sized repo (around 5,000 files), this takes about 30 seconds.
Custom Agent Migration
Here’s where some people hit snags. Custom agents written for 1.x use a slightly different prompt structure than 2.0. Most migrate cleanly, but agents that relied on deprecated tool-use formats need manual updates.
To migrate:
- Open Agents → Manage
- Look for the yellow “Needs Review” tag next to any flagged agent
- Click into the agent
- Antigravity’s built-in migration assistant suggests updated syntax — accept it or edit by hand
- Test the agent on a non-production workspace before relying on it
In my experience, about 80% of custom agents migrate automatically. The other 20% need a tweak to the system prompt or tool list. Plan for an hour if you’ve got several complex agents.
Plugin and Extension Compatibility
Plugins built for Antigravity 1.x aren’t guaranteed to work in 2.0. The extension marketplace will show you which of your installed plugins have updated 2.0-compatible versions.
- ✅ Green check — fully compatible, auto-updated
- ⚠️ Yellow warning — works but with limited features
- ❌ Red x — not yet ported, contact the developer or find an alternative

Common Update Problems and How to Fix Them
Updates rarely fail spectacularly. They fail in annoying, hard-to-diagnose little ways. Here are the issues people actually run into.
Problem 1: “Update Failed — Restart Required”
This usually means a background Antigravity process didn’t close. Open Task Manager (Windows), Activity Monitor (Mac), or htop (Linux), search for “antigravity,” and end any lingering processes. Then retry the update.
Problem 2: Agents Won’t Start After Update
Nine times out of ten, this is a stale cache problem. Try this:
- Close Antigravity
- Navigate to your config folder:
- Mac:
~/Library/Application Support/Antigravity/cache - Windows:
%APPDATA%\Antigravity\cache - Linux:
~/.config/antigravity/cache
- Mac:
- Delete everything inside the
cachefolder (not the folder itself) - Relaunch Antigravity
Your agents will rebuild their context on first run, which adds a minute or two — but they’ll start working again.
Problem 3: Login Loop After Update
If Antigravity keeps bouncing you to the sign-in screen, the auth token from your old version didn’t transfer cleanly. Sign out fully, clear browser cookies for accounts.google.com, restart Antigravity, and sign in fresh.
Problem 4: Performance Feels Worse, Not Better
Sounds counterintuitive, but it happens. New versions sometimes ship with more aggressive default settings — bigger context windows, more parallel agents, richer indexing. If your machine is on the lower end of the spec range, dial these back under Settings → Performance.
Problem 5: Workspace Won’t Open
If a workspace refuses to load after the update, restore from your .agws backup:
- Create a fresh workspace in 2.0
- Go to File → Import Workspace Settings
- Point to your backup file
- Re-add your project folder
Tedious, but it works.
Best Practices for Staying Updated Long-Term
The update you just finished probably isn’t the last one. Google ships meaningful updates to Antigravity roughly every 4–6 weeks. Here’s how to stay current without it becoming a chore.
Enable Background Updates
Under Settings → General → Updates, switch on Download updates in the background. Antigravity will pull new versions silently and prompt you to restart only when it’s safe.
Subscribe to the Release Notes
The Antigravity team publishes detailed release notes for every version. Bookmark them. Reading the notes for two minutes before updating saves you from being surprised by changed defaults or deprecated features.
Test in a Sandbox Workspace
If you rely on Antigravity for production work, keep a small dummy workspace around. After every update, open the sandbox first, run a few standard agent tasks, and confirm everything behaves the way you expect. Catch regressions on the throwaway project, not the client one.
Don’t Skip Multiple Versions
Updating from 2.0.0 straight to 2.0.7 is usually fine. Updating from 1.4 to 2.1 in one jump is asking for trouble. If you’ve fallen badly behind, install intermediate versions in sequence — or at minimum, read every changelog between your current build and the target.
FAQs About Updating Antigravity 2.0
Is updating Antigravity 2.0 free?
Yes. Updates are free for all users on the consumer plan. Enterprise customers receive updates as part of their licensing agreement, though rollout timing may be controlled by your IT administrator.
How long does the update take?
For most users, the entire update process — download, install, and restart — takes 5 to 10 minutes on a stable broadband connection. Workspace migration after the first launch adds another few minutes depending on project size.
Will I lose my agent history after updating?
No, not under normal conditions. Antigravity 2.0 preserves your agent conversation history, custom agents, and workspace settings during the update. That said, backing up your settings before any major update is just smart practice.
Can I roll back to Antigravity 1.x if I don’t like 2.0?
Officially, Google doesn’t support downgrades. Unofficially, you can uninstall 2.0 and reinstall an older version from your local backup — but your 2.0 workspace files won’t open in 1.x, so you’d need to restore from your pre-update backup too.
Do I need to update all my custom agents manually?
Most custom agents migrate automatically. Only agents using deprecated 1.x tool-use formats need manual review, and Antigravity flags those for you with a yellow “Needs Review” tag inside the Agents panel.
What happens to my plugins after the update?
Plugins with 2.0-compatible versions update automatically. Plugins without updates are flagged in the extension marketplace. You can keep using incompatible plugins in limited mode, but for full features you’ll need updated versions.
Why is my update stuck at “Preparing installation”?
Usually a permissions issue or a lingering background process. Close Antigravity fully, restart your machine, and try again. If it persists, run the installer as an administrator (Windows) or with sudo (Linux).
Can I update Antigravity 2.0 on a corporate laptop with restricted permissions?
Often yes, but it depends on your organisation’s policies. If auto-update is blocked, ask your IT admin to push the update through your software management system. The manual installer also requires admin rights on most corporate machines.
Does Antigravity 2.0 work offline after updating?
Some features work offline — basic editing, local file operations, cached agent prompts. But the core agentic features that route through Gemini models need an active internet connection.
How often should I check for updates?
Antigravity auto-checks daily by default. You don’t need to check manually unless you’ve disabled automatic checks. For most users, the in-app notification is enough.
Will updating affect my billing or subscription?
No. Updating to the latest version doesn’t change your plan, pricing, or usage limits. You stay on whatever tier you were on before the update.
What if the update breaks my workflow?
If something genuinely breaks, file a bug report through Help → Report an Issue inside Antigravity. The team monitors these closely after major releases. In the meantime, your backup .agws file lets you restore working settings.
Wrapping Up: Your Update, Your Way
Updating Antigravity 2.0 isn’t complicated when you treat it as a process, not a single button press. Back up first, choose the install method that fits your setup, and give yourself a few minutes after the update to check that everything still hums along.
Key takeaways:
- Always back up workspaces and custom agents before updating
- Auto-update is the easiest path for individual users; manual installers cover everyone else
- Most migration issues are cache or auth problems — both are quick fixes
- Stay current with regular minor updates rather than letting versions pile up
- Read the release notes for two minutes before each update — it saves real headaches later
Next steps: Open Antigravity, check your current version, run the pre-flight checklist above, then pick the update method that suits your environment. Give yourself 15 minutes to do it properly. You’ll be on 2.0 — running faster agents, smoother orchestration, and the redesigned task surface — before your coffee gets cold.
