Hermes · Headless Chromium for agents

Give your agents a body.
Not another API.

Hermes is the real browser layer behind ZeroGravity. Your agents click, scroll, type, log in, screenshot, and reason over the live web — inside sandboxed Chromium with per-second billing and AES-GCM-encrypted BYO keys. Direct0r drives. You hold the keys.

How it works

Three steps from prompt to a real browser doing real work.

01

Connect your key

One-click Managed (we run the pool) or BYO Browserbase. Keys are AES-GCM encrypted at insert and never returned to the client.

02

Direct0r drives

Your model emits typed tool calls — web.search, web.click, web.read. Hermes executes them inside a fresh sandboxed Chromium session.

03

You watch & pay per second

Every action streams to a live iframe in your IDE. The meter ticks per second, charged from your wallet. Stop any time.

The connector

One connector. Every model. Every workflow.

Hermes is the bridge between your AI and the real internet. Wire it once and every tool, model, and project across ZeroGravity gets a browser body — Claude, GPT, Gemini, DeepSeek, or your local LLM. No SDKs to wrangle. No scraping libraries to maintain.

  • Works with every model in your router
  • Per-project sessions, per-user RLS
  • Live timeline replay for every action
  • Pause, approve, or revoke at any frame

Why use Hermes

The fastest way to put a browser in your agent loop — without losing control.

Ship features that need the live web
For founders

Ship features that need the live web

Stop building brittle scraping pipelines. Hermes turns 'go check this site' into a one-line tool call.

Bring your own everything
For engineers

Bring your own everything

Your Browserbase key, your concurrency, your bill. Hermes adds zero markup in BYO mode.

Encrypted, scoped, auditable
For teams

Encrypted, scoped, auditable

AES-GCM at rest, RLS per user, every session logged. Revoke a key and every active session dies.

Capabilities

A browser shaped like an API. An API shaped like a teammate.

Real Chromium
Cookies, JS, anti-bot evasion. The web as a user sees it.
Live view
Watch the agent work in a sandboxed iframe — every click visible.
Tool-call native
Direct0r streams web.search, web.click, web.read as typed cards.
Per-second meter
No flat $99/mo. You pay only for the seconds Hermes is awake.
Plan Mode aware
Hermes respects Plan Mode — no side effects until you approve.
Encrypted at rest
BYO keys are AES-GCM encrypted with a workspace-scoped secret.
Use cases

Everything that used to require a scraping engineer.

Live research

Cite live sources, not stale training data.

Price & inventory

Pull real numbers from real merchants in real time.

Form filling

Fill, submit, confirm — with approvals at each step.

QA flows

Run end-to-end tests against your own preview URL.

Repo browsing

Read GitHub issues, PRs, diffs — without an API token.

Dashboards

Screenshot any metric page and chart it in your app.

Two ways to run

Managed when you want simple. BYO when you want control.

Managed

One-click. We run the browsers.

  • Shared Browserbase pool
  • Billed from your ZG wallet, per-second
  • Region-pinned, isolated session per project
≈ $0.10 / minute
BYO Pro

Bring your own Browserbase.

  • Your key, your bill, your throughput
  • Encrypted with AES-GCM, revoke anytime
  • Unlimited concurrency — limits are yours

Trust posture

Your keys never leave the box. Your sessions never leak.

BYO Browserbase keys are encrypted with AES-GCM at insert, decrypted only inside server functions for the outbound call, never returned to the client. Sessions are RLS-scoped per user, revocable in one click.
