Hermes and Antigravity are two of the most powerful agent tools you can run together: Google Antigravity is an agentic coding environment, and Hermes is a free, open-source agent for everything else. Wire them into one Agent OS and you get coding power plus free automation. Here's how Hermes and Antigravity work together.

What Is Google Antigravity?
Antigravity is Google's agentic coding tool — an environment where an AI agent plans, writes and runs code for you, built around Google's models. It's one of the stronger coding agents available, and like Claude Code or Codex it works best as part of a bigger system rather than in isolation.
Why Use Antigravity With Hermes?
Because they cover different jobs. Antigravity is a coding powerhouse; Hermes is a free, open-source agent that runs any model (including free and local ones), handles always-on background tasks, voice and automation, and never locks you into one provider. Run them together and you get the best of both — and you can switch models the moment one goes down.

How To Connect Hermes And Antigravity
The cleanest way is inside an Agent OS, where Antigravity, Hermes, Claude and Codex all plug in as separate tools and share one memory system. You code in Antigravity, automate with Hermes, and a shared memory keeps them on the same context. See multi-agent orchestration.
Antigravity vs Hermes: When To Use Which
Use Antigravity when the job is heavy coding — building apps, tools and complex projects. Use Hermes when you want free or local models, always-on automation, browser and computer use, or voice. They aren't rivals; they're a coding brain and an automation body that complement each other.

The Free And Local Angle
Hermes is where the free part comes in: point it at a free model (Gemma 4 locally, or Grok via OAuth) and your automation costs nothing, while Antigravity handles the coding. For a fully free stack, see how to use Hermes for free. For the vibe-coding side, see vibe coding with Antigravity.

Frequently Asked Questions
Can you use Hermes with Antigravity?
Yes — run both inside an Agent OS as separate tools sharing one memory. Use Antigravity for coding and Hermes for free/local models and automation.
What is Antigravity?
It's Google's agentic coding tool — an AI environment that plans, writes and runs code for you, similar in spirit to Claude Code or Codex.
Why run both instead of one?
Antigravity is a coding powerhouse; Hermes adds free and local models, always-on automation and voice. Together they cover far more than either alone.
The Bottom Line
Hermes and Antigravity together give you a coding brain (Antigravity) and a free automation body (Hermes) in one Agent OS with shared memory. Use Antigravity to build, Hermes to automate for free — and get them plugged in together inside the AI Profit Boardroom.
Going Deeper: The Hermes And Antigravity Pairing Playbook
The sections above cover what each tool is. This part goes further: what Google Antigravity specifically brings to the pairing, what Hermes should own, real combined workflows, and the setup mistakes that quietly waste your first week.
What Antigravity Actually Brings To The Table
Antigravity is not just a chat window bolted onto an editor. It is an agentic IDE: the agent gets an editor, a terminal and a browser it can drive on its own, built around Google's models. That browser piece matters most. When the agent finishes a feature, it can open the thing it just built, click through it like a real user, and record what happened — browser-in-the-loop verification instead of you manually checking every change.
It also works at a higher altitude than a normal coding assistant. Instead of watching every keystroke, you review the plans, task lists, screenshots and browser recordings the agent produces as it works. You manage outcomes rather than lines of code — closer to reviewing a contractor's finished work than pair programming.
What Hermes Should Own In The Pairing
Hermes owns everything that is not a coding session. Model freedom — free, local or hosted, swapped at will. Scheduled and always-on work that keeps running after the laptop closes. Messaging, voice and browser automation out in the wild rather than inside one project. And memory: Hermes is the natural keeper of the shared notes both tools read from.
A simple way to hold it: Antigravity is the workbench you sit at; Hermes is the worker who never goes home.
Three Combined Workflows That Work
- Build, then babysit. Antigravity builds the landing page, tool or app while you review its plan and recordings. Once shipped, Hermes takes over: checking the live page on a schedule, watching for errors, reporting back daily. Antigravity's job ends at ship; Hermes' job never ends.
- Research overnight, build in the morning. Hermes gathers competitor notes, requirements and examples overnight on a free model and writes them into shared memory. In the morning you open Antigravity, point it at that brief, and let it build with full context it never had to guess.
- The tool factory. Use Antigravity to write small single-purpose scripts — a scraper, a formatter, a report generator. Hand each finished script to Hermes to run on a schedule with a free local model. Antigravity builds the machine once; Hermes turns the handle forever at zero cost.

A Sharper Test For Which Tool Gets The Job
- Does the task end when code ships? Antigravity. Building is a project with a finish line, and that is what an agentic IDE is for.
- Does the task repeat forever? Hermes. Anything daily, hourly or always-on belongs to the agent that stays awake.
- Does it need checking against a live page? During the build, use Antigravity's own browser verification. After launch, use Hermes on a schedule.
- Does it have to cost nothing? Hermes on a local model. Route high-volume routine work there, and save the heavier coding sessions for where they earn their keep.
Setup Gotchas Worth Knowing In Advance
- One memory, one source of truth. Give both tools the same shared folder, but split the lanes: Antigravity owns project repositories, Hermes owns the memory vault, and handoffs happen through a short brief file rather than both editing the same document at once.
- Never point two agents at one repository simultaneously. Let Antigravity finish its run before Hermes touches the same files. Overlapping edits create confusing half-finished states that take longer to untangle than the work saved.
- Keep everything under version control. An agent mistake should be a revert, not a rebuild. Commit before and after big agent sessions.
- Plan around rate limits. Preview-stage tools throttle heavy use. Batch your Antigravity work into focused sessions instead of drip-feeding requests all day, and let Hermes absorb the low-stakes volume on free models.
- Write the brief before the session. Context that lives only inside one chat window dies with that window. A brief file in shared memory survives, and both tools can read it.
More Questions People Ask About This Pairing
Do I need to pay to use Antigravity? Google launched Antigravity as free to use with a Google account, with rate limits on heavy usage. Terms on preview products do change, so check the current ones — but the pairing logic holds either way, because Hermes carries the free side of the stack.
Can Hermes trigger Antigravity automatically? Treat it as a handoff, not a remote control. Antigravity sessions work best started by you; Hermes prepares the brief beforehand and handles everything after. The shared memory folder is the bridge between them.
What happens when Antigravity is rate-limited or down? Nothing stops. That is the whole argument for an Agent OS: Hermes keeps running on any model, and coding work can shift to Claude Code or Codex plugged into the same system until Antigravity is back.
Do they share memory automatically? No — out of the box, each tool keeps its own context. You create the shared folder and tell both tools to read it and update it. That one habit is most of what makes the pairing feel like a single system instead of two apps.
One System, Two Specialists
Antigravity gives you a coding agent with its own browser and hands; Hermes gives you a free worker that never clocks off. Split the work by whether it ends or repeats, keep one shared memory between them, and the pairing stops being two tools — it becomes a system that builds in the day and earns around the clock.
