The best browser for Hermes is the free local Chromium that Hermes Agent installs for itself, and I score it 9.3 out of 10.

Second place goes to your own Chrome with real profile browsing at 8.9, and third place goes to Brave, Edge or Chromium at 8.6.

Hermes Agent is the free, open-source AI agent from Nous Research, and its browser toolset can drive eight different browsers or browser backends.

I've scored every one of them on five things: how well it works out of the box, how reliable it is with logins, how fast it is, what it costs and how private it is.

The facts come from the official Hermes browser docs and the Browser Automation menu on my own Hermes v0.21.4 install.

The scores are my own judgement, and nobody measured them in a lab, so use them as a guide to where to start.

The Best Browser For Hermes: Top 3 At A Glance

  • 🥇 Hermes's own local Chromium scores 9.3 out of 10, because it's the default, it's free and it's private.
  • 🥈 Your own Chrome with real profile browsing scores 8.9 out of 10, because nothing else handles logins as cleanly.
  • 🥉 Brave, Edge or Chromium scores 8.6 out of 10, because it does the same job for people who don't live in Chrome.

The Full Scorecard

I scored each option out of 10 on five things and averaged them.

Rank Browser or backend Out of the box Logins Speed Cost Privacy My score
1 Local Chromium ("Local Browser") 10 7.5 9 10 10 9.3
2 Your own Chrome, real profile 8.5 10 8.5 10 7.5 8.9
3 Brave, Edge or Chromium 8 9.5 8.5 10 7 8.6
4 Browser Use Cloud 7.5 9 8 6 6 7.3
5 Browserbase 7 8 8 6 6 7.0
6 Camofox 5 7.5 7 9 9 7.5
7 Lightpanda 6.5 4 10 10 10 8.1
8 Firecrawl cloud browser 7 5.5 7.5 6 6 6.4

The rank isn't a straight sort of the last column, and I want to be upfront about why.

Camofox and Lightpanda score well on cost and privacy, but each one does a narrow job, so I rank them below the hosted browsers that suit more people.

These are my scores, and you might weigh them differently for your own work.

What The Hermes Browser Is

The browser toolset lets Hermes open pages, click, type, scroll, fill in forms and extract information.

The docs say pages are represented as accessibility trees, which are text snapshots where each button and field gets a short reference the agent can click.

The browser underneath is swappable, and the docs call each choice a backend.

There are two drivers on top of the backend.

Driver What it does When you get it
Browser Use mode The agent writes short Python that runs in the browser, through one tool called browser_exec. It's the default when the session also has terminal access.
Built-in browser tools The agent calls separate tools such as browser_navigate, browser_click and browser_type. You get it with /browser use off, with Camofox or on a locked-down platform.

I explain both in more depth in my posts on the Hermes Agent browser and Hermes Agent browser use.

How I Scored The Browsers

Here's what each column means.

  • Out of the box measures how little you have to do after installing Hermes.
  • Logins measures how reliably the browser stays signed into sites.
  • Speed reflects what the docs say about start-up and weight, because I haven't run my own stopwatch test.
  • Cost gives 10 to free options and less to anything billed in credits.
  • Privacy rewards browsing that stays on your own machine and stays away from your personal accounts.

The 8 Best Browsers For Hermes, Reviewed One By One

1. Local Chromium ("Local Browser") — 9.3

Hermes installs a pinned Chromium and the agent-browser driver for you, and hermes update keeps them current.

The setup menu on my install labels it "★ recommended · free" and describes it as "Headless Chromium, no API key needed".

The docs say local browsing uses this packaged Chromium and never touches your installed Chrome.

It runs in a clean, throwaway profile, which is why I mark logins down and privacy up.

Strengths: It needs zero setup, it costs nothing and it works on a server with no Chrome installed.

Weaknesses: It's logged into nothing, and the docs say the browser toolset can't download files.

Best for: It's best for research, public pages and your first week with Hermes.

2. Your Own Chrome With Real Profile Browsing — 8.9

Real profile browsing is switched on with browser.use_real_profile: true.

Hermes copies your active profile into a managed snapshot under ~/.hermes/browser-profile/ and launches your real Chrome binary on that copy.

The docs say launching the real binary is what keeps operating-system-encrypted cookies readable, especially on macOS.

The snapshot runs headless, the logins are re-synced each time a fresh session starts and your live profile is never opened directly.

Strengths: It gives the agent your existing logins with no dialogs and no manual sign-in.

Weaknesses: You have to fully quit Chrome first, and every page the agent opens runs with your real accounts.

Best for: It's best for dashboards, admin panels and any tool that has no API.

3. Brave, Edge Or Chromium — 8.6

The docs list Chrome, Edge, Brave, Brave Origin and Chromium as supported for real profile browsing.

They also say /browser connect detects Brave, Chrome, Chromium and Edge when it looks for a browser.

Hermes copies whichever of these is your operating system default.

Strengths: You keep your usual browser, and Brave users keep their privacy defaults for daily browsing.

Weaknesses: On Windows, the docs say a running Chrome, Edge or Brave holds an exclusive lock on its login files, so the browser has to be fully closed.

Best for: It's best for Edge-first Windows users and Brave-first privacy fans.

4. Browser Use Cloud — 7.3

Browser Use Cloud is managed Chromium on someone else's servers.

The docs say stealth and residential proxies are on by default, CAPTCHA solving is included and persistent profiles keep cookies, local storage and saved passwords.

You supply BROWSER_USE_API_KEY, or you use the managed version that comes with a paid Nous Portal subscription.

Strengths: It needs no local browser at all, and it's the hosted option with reusable profiles.

Weaknesses: It costs credits, and your sessions live with a third party.

Best for: It's best for always-on agents on a server.

5. Browserbase — 7.0

Browserbase needs BROWSERBASE_API_KEY and BROWSERBASE_PROJECT_ID.

The docs list basic stealth as always on, residential proxies as on by default, advanced stealth as a Scale plan feature and a maximum session timeout of six hours.

It's also the one hosted backend the docs list as fully supporting native pop-up dialogs through the browser_dialog tool.

Strengths: It has long sessions and graceful fallback on lower plans.

Weaknesses: It's paid, and the best stealth sits on a higher plan.

Best for: It's best for teams already invested in Browserbase.

6. Camofox — 7.5

Camofox is a self-hosted server that wraps Camoufox, a Firefox fork with fingerprint spoofing built in.

You run it in Docker and point Hermes at it with CAMOFOX_URL.

The docs say each session gets a random identity unless you set browser.camofox.managed_persistence: true.

Camofox has no Chrome DevTools endpoint, so Hermes keeps the built-in browser tools for it instead of Browser Use mode.

Strengths: It's free, local and built to look less like automation, and it can show a live view over VNC.

Weaknesses: It needs Docker, and persistence depends on the server build you run.

Best for: It's best for technical users who want anti-detection without a cloud bill.

7. Lightpanda — 8.1

Lightpanda is a headless browser written from scratch in Zig.

The Hermes docs say it starts instantly, runs nine times faster than Chrome and uses sixteen times less memory.

It has no graphical renderer, so screenshots aren't available, and it holds one page per session.

With the built-in tools, Hermes falls back to Chrome automatically for actions Lightpanda doesn't support.

Strengths: It's the lightest option by a distance, and it needs no Chromium or Node.

Weaknesses: It's text-only, and it's the wrong tool for login-heavy work.

Best for: It's best for small servers and bulk reading.

8. Firecrawl Cloud Browser — 6.4

Firecrawl offers cloud browsers alongside its scraping service.

You add FIRECRAWL_API_KEY and select it under Browser Automation, and the docs give a default session length of 300 seconds.

Strengths: One key covers search, scraping and browsing.

Weaknesses: Sessions are short by default, and it's billed in credits.

Best for: It's best for people who already pay for Firecrawl.

Chrome Versus /browser connect Versus Real Profile

People mix these three up, so here's the short version.

Method What it is Logins Where it works
Local Browser It's Hermes's packaged Chromium in a clean profile. It has none. It works everywhere.
/browser connect It attaches Hermes to a running Chromium browser over port 9222. A dedicated debug profile starts signed out. It works only in the terminal chat.
Real profile browsing It drives a copy of your active profile. It has your real logins. It works on any backend.

The docs explain that since Chrome 136, the debugging port is ignored on your default profile, so /browser connect needs Chrome launched with a separate --user-data-dir.

That's why I score real profile browsing higher for logins and keep /browser connect for the times I want to watch the agent in a real window.

How To Set Up The Winner

The winner takes five steps.

  1. Run hermes update.
  2. Run hermes tools list and confirm browser is enabled.
  3. Run hermes tools, open Browser Automation and select "Local Browser".
  4. Run hermes pm install agent-browser only if the menu says the browser needs setup.
  5. Ask Hermes to open a public page and read you the heading.

If you want to watch it work, you set browser.headed: true in the config file.

Safety Verdict: Logged-In Sessions And Approvals

I score safety separately, because it changes which browser you should pick.

Setup My safety rating Why
Local Chromium, clean profile It's the safest. The agent has no accounts to misuse.
Cloud browser, fresh session It's safe for accounts, with a data trade-off. Pages pass through a provider.
Real profile browsing It needs care. The docs say it isn't an isolation boundary.
Any browser with approvals off I'd avoid it. The docs warn that unrestricted mode gives no protection against prompt injection.

Four built-in protections are worth knowing.

The vault, run with hermes vault, encrypts passwords on your machine and fills them into the page without the model seeing them.

The setting browser.restrict_evaluate: true blocks sensitive JavaScript such as cookie and storage access when you browse unknown pages with a logged-in profile.

Turning real profile browsing off makes Hermes delete the copied profile on the next browser use.

Hermes asks before it closes your browser to free a locked profile, and it never does that on its own.

In my Hermes computer use video, I called this level of access experimental and suggested a secondary machine, and that advice applies here too.

What I'd Skip

Firefox as your default browser won't work for real profile browsing, because the docs say it fails closed.

Safari isn't listed as supported.

The computer_use toolset is for desktop apps, and the docs say browser work, including signed-in pages, goes through the browser toolset.

The browser is overkill for simple lookups, because the docs say web_search and web_extract are faster and cheaper.

The Final Verdict

Start with the local Chromium, because it's free, private and already installed.

Add real profile browsing with Chrome, Brave or Edge when a job needs your logins.

Pay for Browser Use Cloud or Browserbase only when your agent lives on a server or a site keeps blocking you.

Keep Lightpanda and Camofox in your back pocket for the two special cases they're built for.

If you're choosing the rest of your stack, my scored list of the best Hermes Agent tools is the natural next read.
