ZeroG vs. Open-Source Antigravity Remotes
Short answer: Google Antigravity has no official mobile app, so two kinds of tools have emerged to fill the gap: dedicated companion apps like ZeroG, and community open-source projects that mirror your Antigravity session to a phone browser. Both connect to the same running desktop session — they differ mainly in setup effort, cost, and how they reach you outside your home network.
How open-source Antigravity remotes work
Several community projects exist that bridge Antigravity to a mobile browser over your local network. They're free and self-hosted. Setting one up typically means cloning a repository, running a local server or terminal commands, and — if you want access away from your home Wi-Fi — configuring your own tunnel (for example ngrok or a Cloudflare Tunnel). Feature sets vary from project to project and change as maintainers update them, so check each project's own repository for current capabilities before relying on one.
How ZeroG works
ZeroG is a dedicated iPhone app built specifically for Antigravity. You install the ZeroG extension in Antigravity, pair your phone by scanning a QR code, and you're connected — no repository to clone, no server to run, no tunnel to configure. It connects over Wi-Fi or cellular through an encrypted relay, and your code and AI model stay on your own machine the whole time.
Side-by-side
| ZeroG | Open-source remotes | |
|---|---|---|
| Setup | Install app + extension, scan a QR code — about a minute | Clone a repo, run a server/terminal commands; setup time varies by project |
| Access away from home Wi-Fi | Built in — works over cellular out of the box | Usually requires configuring your own tunnel (e.g. ngrok, Cloudflare Tunnel) |
| Maintenance | Updated and maintained as an App Store app | You maintain the install; depends on the project staying active |
| Cost | Free (ad-supported); Pro is $19.99/mo, no ads, unlimited devices | Free, self-hosted |
| Support | Email support, App Store reviews | Whatever the project's maintainers and community provide |
| Where code/AI runs | On your own machine; ZeroG only relays messages | On your own machine, same principle — verify per project |
Which should you use?
If you enjoy tinkering, already run your own tunnels, and mainly need access on your home network, an open-source remote is a reasonable, free choice. If you want it working in under a minute and reachable from anywhere without setting up infrastructure yourself, ZeroG is built for that.
ZeroG is the mobile companion for the Google Antigravity IDE — available now on the App Store.

Are there free or open-source alternatives to ZeroG?
Yes. Several community, open-source projects mirror an Antigravity session to a phone browser over your local network. They're free and self-hosted, but typically require cloning a repository, running your own server or terminal commands, and setting up a tunnel yourself for access beyond your home Wi-Fi.
Is ZeroG open source?
No. ZeroG is a closed-source commercial app distributed through the App Store. It's free to use with ads and one paired device; ZeroG Pro ($19.99/month) removes ads and adds unlimited paired devices.
Which should I use, ZeroG or an open-source remote?
If you're comfortable running your own server, configuring a tunnel, and maintaining the setup yourself, an open-source remote can work well and costs nothing. If you want a working setup in about a minute that also connects over cellular without any tunnel configuration, ZeroG is built for that.
Is ZeroG affiliated with Google or the Antigravity team?
No. ZeroG is an independent product and is not affiliated with, endorsed by, or sponsored by Antigravity or Google DeepMind.
