Here’s how to combine them. Hermes and Antigravity are two of the most useful free AI tools around — and they’re better together. Google Antigravity is a free AI coding tool that builds apps; Hermes is an always-on open-source agent. Plug both into one agent OS and you get the best of each.
Here’s how they fit together and how to run them side by side.

Key takeaways
- Antigravity is Google’s free AI coding tool; Hermes is a free, open-source, always-on agent.
- They’re complementary — run both as agents inside one agent OS.
- Orchestrate them together (with Paperclip), share a memory, and switch models freely.
- Get both pre-wired in the AI Profit Boardroom Agent OS.
Hermes + Antigravity: What’s the Connection?
People search “Hermes Antigravity” because they’re trying to work out how the two relate. The simple answer: they’re both agents you can run in one system. Google Antigravity is a free AI coding tool that builds apps; Hermes is a free, open-source agent that’s always on and great at orchestration and long-horizon work.
You don’t pick one — you plug both into an agent OS and use whichever fits the job, with them sharing context and even working as a team.
What Is Google Antigravity?
Antigravity is Google’s free, agentic AI coding tool — it builds working apps for you rather than just suggesting code. It’s a strong option for coding tasks, and because it’s free it slots nicely into a wider setup.
For a full rundown, see my Google Antigravity guide.
How to Use Hermes and Antigravity Together
- Plug both into your agent OS — Hermes and Antigravity side by side, alongside Claude and Codex.
- Add a shared memory system (I use Obsidian) so both read the same context.
- Orchestrate with Paperclip — hand a task to a team of agents and let them complete it together.
- Switch freely — use Antigravity for app-building, Hermes for always-on workflows and automation.
This is the ‘system, not model’ approach — see my agentic OS for Hermes guide.
When to Use Which
| Task | Reach for |
|---|---|
| Building an app or coding project | Antigravity |
| Always-on / scheduled automation | Hermes |
| Long-horizon autonomous jobs | Hermes |
| Orchestrating several agents | Hermes + Paperclip |
| Free, agentic everyday work | Either — both are free |
The point of running both is that you never have to compromise — you route each job to the tool that’s best at it.
Model Resilience: A Quiet Win
Running both in one system also makes you resilient. If one tool or model is down or rate-limited, you switch to the other and keep working. When everything lives in a single agent OS, an outage is a shrug, not a blocker.
What You Can Build With Both
With Hermes and Antigravity in one system, a typical flow looks like this: use Antigravity to build the app or tool, then hand it to Hermes to run, schedule and automate around the clock. Antigravity ships the thing; Hermes keeps it working and wires it into your other workflows — content, outreach, research — without you babysitting it.
Two Free Tools, One System
The appeal here is that both are free — Antigravity from Google, Hermes open source — so you’re building a genuinely capable setup without a subscription. The only thing that can cost tokens is the model behind Hermes, and even that can be a free API or a local model. Put them together in an agent OS and you’ve got serious capability at effectively zero software cost.
Do You Need Both?
Not strictly — either one is useful alone. If you only build the occasional app, Antigravity on its own is fine. If you want always-on automation and orchestration across several agents, Hermes is the backbone. Most people who use both end up wanting them in one place, which is exactly what an agent OS gives you. See my how to build an agentic OS guide.

FAQ
How do Hermes and Antigravity work together?
They’re both agents you can run in one agent OS. Antigravity handles app-building, Hermes handles always-on orchestration and automation — sharing a memory and switching as needed.
What is Google Antigravity?
It’s Google’s free, agentic AI coding tool that builds working apps for you, not just code suggestions.
Should I use Hermes or Antigravity?
Both. Use Antigravity for coding and app builds, Hermes for always-on workflows and long-horizon automation — run them side by side in one system.
Are Hermes and Antigravity free?
Yes — Antigravity is free from Google, and Hermes is free and open source. You only pay for whatever model you plug into Hermes, and that can be free too.
Can I run them in one dashboard?
Yes — plug both into an agent OS with a shared memory and Paperclip orchestration, and manage them from one screen.
The Bottom Line
Hermes plus Antigravity in one agent OS gives you coding and always-on automation together. The ready-made setup is in the AI Profit Boardroom.
