Antigravity Dev Stack
BeginnerGoogle Antigravity runs parallel agents and an editor in one app, with Gemini by default and Claude a click away.
Published 27 September 2026
About Antigravity Dev Stack
Google Antigravity is Google's agent-first development environment. Its Agent Manager is the main view: you hand it a task, and it splits the work into subtasks and runs agents on them in parallel, each in its own context, while you review their plans and results. An Editor mode sits beside it for the hands-on work, and the agy CLI runs the same agents from a terminal. Editor and agent are one Google product, which is why this stack has a single Antigravity at its core.
Models come from Antigravity's own picker. Gemini is the default, with Flash models for fast everyday work and Gemini Pro for harder problems; Claude Sonnet and Opus sit in the same picker, as does OpenAI's open-weight gpt-oss model. Several can be in use at once across different agents, and all of them are available on the free tier within its weekly limits.
Work keeps going away from the desk through Remote Control: sessions run on your own machine, and you check progress, answer an agent's questions, and review output from a browser on any device, including a phone, where it installs as a web app with push notifications. The host has to stay on and awake. For sessions that outlive a closed laptop, Antigravity's headless daemon can run on an always-on VPS, reached the same way.
Code lives on GitHub by default, or on GitLab when source control has to be self-hosted. Docker and a CI/CD pipeline are common additions once a project needs environment parity or tests on every push; neither is needed to get started.

When to Use Antigravity Dev Stack
- →Handing a broad refactor to parallel agents and reviewing their plans instead of every keystroke
- →Switching between Gemini Flash for quick edits and Claude or Gemini Pro for a hard problem
- →Checking on a long test or build run from a phone and answering an agent's question
- →Keeping agent sessions alive on a server after the laptop is closed
- →Trying an agent-first workflow on the free tier before committing to a paid plan
Pros
- Parallel agents are the core workflow, not an add-on to a traditional editor
- Model choice across Gemini, Claude, and gpt-oss, free tier included
- Remote Control works from any browser, so no separate mobile app is needed
- Paid usage comes with Google AI plans many developers already have
Cons
- The agent-first layout takes adjusting to for developers used to a classic editor
- Remote Control has no native mobile app; phones use the installable web app
- Parallel agents produce more changes than one person can review closely
- Closed-source product whose workflow depends on Google's product decisions
LLM Options for Antigravity Dev Stack
Antigravity Dev Stack powered by Google Gemini
Gemini is the default here and the family Antigravity is built around: Flash models are fast enough for everyday edits and the Agent Manager's parallel subtasks, and Gemini Pro's long context suits planning work that spans the whole repository. Usage draws on Antigravity's free weekly limits or a Google AI plan.
Antigravity Dev Stack powered by Claude
Claude Sonnet and Opus sit in Antigravity's picker, a common choice for large multi-file changes and careful reasoning about unfamiliar code. They're billed through your Google plan's quota rather than an Anthropic subscription, and a premium model draws that quota down faster than Gemini Flash.
Antigravity Dev Stack powered by OpenAI
OpenAI is represented by its open-weight gpt-oss model, not the GPT frontier models, so it's a second opinion or a lighter option rather than a way to run GPT-5 inside Antigravity. Useful for comparing a third model's approach on the same task within the free tier.
These are highlighted picks. To see all the tools, check the LLM category.
Version Control Options for Antigravity Dev Stack
Antigravity Dev Stack with GitHub
GitHub is the default here: the largest pull-request and Actions ecosystem, and the host that agents' version-control work in Antigravity most often targets.
Antigravity Dev Stack with GitLab
GitLab bundles source control, merge requests, and CI/CD in one self-hostable platform, the pick for teams that need code and pipeline data to stay on their own infrastructure.
Antigravity Dev Stack Add-ons
Each addition below extends this stack with a capability the base stack works fine without. None are required: include the ones your product actually needs when building this stack, and skip the rest.
Server Add-ons
Add a server when you want the agent to keep running somewhere other than your own laptop, reachable at any time and not tied to your machine staying on. Some agents also offer their own managed cloud sessions as an alternative to self-hosting; check the stack's own description for details.
Antigravity Dev Stack with Hetzner
Hetzner is the default here: a CX23 with 4 GB of RAM is about €5.49/mo, the lowest price per gigabyte in this list. Google publishes no memory minimum for Antigravity's headless daemon, since the models run on Google's side; 4 GB leaves room for the builds and tests the agents run.
Antigravity Dev Stack with DigitalOcean
DigitalOcean's 4 GB Droplet is $24/mo, several times Hetzner's price for the same memory, in exchange for a more polished dashboard and wider region coverage. It has no Antigravity-specific image, so this is a plain Linux server for the headless daemon.
Antigravity Dev Stack with Hostinger
Hostinger's KVM 1 has 4 GB of RAM at $6.49/mo introductory, renewing at $11.99/mo. A budget pick for one always-on Antigravity host; its agent templates target other tools, so Antigravity goes on a plain Linux image.
These are highlighted picks. To see all the tools, check the Hosting & Cloud category.
Remote Access Add-ons
Add remote access when you want to reach an agent running on another machine — a VPS or a home server — without exposing it to anyone but you.
Antigravity Dev Stack with Tailscale
Add Tailscale alongside a server to reach it privately over SSH for logs, git, and anything Remote Control doesn't cover, without exposing it to the public internet. The personal tier is free.
Code Review Add-ons
Add code review when you want an AI reading every pull request before it merges: it comments on the diff so bugs, security issues, and inconsistencies surface before a human has to catch them.
Antigravity Dev Stack with CodeRabbit
Add CodeRabbit when you want an AI reviewer on every pull request: it installs as a GitHub or GitLab app, summarizes the diff, and leaves line-level comments before anyone merges, with a free tier for open-source repos.
Antigravity Dev Stack with Greptile
Add Greptile when you want review that reads the whole repository rather than just the diff: it indexes the codebase so its GitHub and GitLab pull request comments carry wider context, and it can be self-hosted.
Antigravity Dev Stack with Cursor Bugbot
Add Cursor Bugbot when a bug-focused reviewer is enough: it reviews GitHub or GitLab pull requests whatever wrote the code, though it bills through a Cursor account and plan rather than its own subscription.
CI/CD Add-ons
Add CI/CD when you want a dedicated pipeline for running tests, linting, or multi-stage builds before a deploy goes out. Many hosting platforms already redeploy automatically on every push on their own — a CI/CD tool adds the most value on top of that by gating the deploy on a passing test suite, and matters even more when the hosting choice does not auto-deploy at all, such as a self-hosted server.
Antigravity Dev Stack with GitHub Actions
Add GitHub Actions when the repo lives on GitHub and you want tests and deploys running automatically on every push.
Antigravity Dev Stack with GitLab CI/CD
Add GitLab CI/CD when the project is on GitLab and needs the same automated pipeline, defined in a .gitlab-ci.yml file that can run entirely on your own infrastructure.
These are highlighted picks. To see all the tools, check the CI/CD Pipelines category.
Containerization Add-ons
Add containerization when you want the app packaged the same way across local development, staging, and production, or need to deploy somewhere that isn't a managed serverless platform.
Antigravity Dev Stack with Docker
Add Docker when the project needs environment parity between a developer's machine and production, or when onboarding a new teammate should be a single command instead of a page of setup instructions.
These are highlighted picks. To see all the tools, check the Containerization category.
Frequently Asked Questions about Antigravity Dev Stack
Can Antigravity keep working when I'm away from my computer?
Yes, through Remote Control. Sessions run on your own machine, and you follow them from a browser on any device, including a phone, where Antigravity installs as a web app that sends push notifications when an agent finishes or needs input. The catch is that the host machine has to stay on, awake, and online, so a closed laptop stops the work. To keep going with the laptop off, Antigravity's headless daemon can run on an always-on VPS, which Remote Control reaches the same way. Google doesn't run Antigravity sessions in its own cloud for individual users.
Can I use Claude or GPT instead of Gemini?
Claude, yes: Sonnet and Opus are in Antigravity's model picker, even on the free tier, and are billed through your Google plan rather than an Anthropic subscription. GPT, only partly: the OpenAI model on offer is the open-weight gpt-oss, not GPT-5-class models. Gemini stays the default, and each agent can use a different model, so mixing them in one project is normal.
How is this different from using Cursor?
Cursor is an editor first, with an agent and cloud agents built into it, and Grok as its headline model among several providers. Antigravity leads with the Agent Manager, which splits a task and runs parallel agents while the editor plays a supporting role. Cursor starts cloud agents from its web and iOS apps; Antigravity keeps sessions on your own machine or server and lets you steer them from a browser. Pick Cursor to stay close to the code, Antigravity to delegate larger tasks.
What does it cost to use it heavily?
The free tier includes every model but has weekly rate limits, which parallel agents reach quickly. Heavier use means a Google AI plan: Pro for more headroom, or one of the two Ultra tiers for 5x or 20x Pro's limits. Premium models draw the shared quota down faster than Gemini Flash. The Pricing section has the current figures.
Can parallel agents step on each other's changes?
They can, when two subtasks touch the same files. Antigravity runs each agent in its own context and has you review plans and diffs, but deciding how a task splits still matters: tasks cut along module lines merge cleanly, while two agents editing one shared config file leave you resolving conflicts. The practical limit is usually review time, since several agents produce more changes than one person can read closely.
Scores
Popularity3/5
Google's brand and a high-profile launch put it in front of many developers, though its user base is well behind Cursor and VS Code.
Learning Curve2/5
Plain-language tasks work from day one, but directing parallel agents from the Agent Manager is a different habit from editing code directly.
Flexibility3/5
Three model families in one picker and a desktop app, CLI, and browser remote control, but only Google's own agent, with no slot for another vendor's.
Performance4/5
Gemini Flash responds quickly, and parallel subagents finish broad tasks faster than one agent working in sequence; free-tier rate limits are the usual bottleneck.
Portability3/5
Projects are plain files and git history, but Agent Manager workflows and Antigravity-specific agent configuration don't carry over to another tool.
