Automation leaves marks
A browser started by an automation library often sets flags that a person’s browser never does, and a script layer that hides them changes built-in functions a page can inspect. Sites read both before anything else.
AI agents / Best anti-detect browsers for AI agents
The best anti-detect browser for an AI agent sets its fingerprint in the engine, gives every task an isolated profile, speaks MCP, and limits what the agent may do. On the 13 checkpoints below, Browz scores 13 of 13, ahead of AliasMode, AntiBrow and Steel on 9.
Who wrote this. We make Browz, and we rank it first. So that the ranking can be checked, this page publishes the criteria it uses and how they were chosen, scores every product the same way, links the public page behind every statement about another product (each read on 13 Nov 2026), and marks anything those pages don’t state as “Not documented”. We ran no tests on other products for this page and say nothing about how they do on detection tests. If something here is wrong or out of date, contact support and we will correct it.
Why agents need this
An agent is a visitor that arrives through automation, works on many tasks, and comes back tomorrow. Four things follow, and they are what the criteria below measure.
A browser started by an automation library often sets flags that a person’s browser never does, and a script layer that hides them changes built-in functions a page can inspect. Sites read both before anything else.
A site compares the user agent with the client hints, the fonts with the operating system, the timezone with the address the visit comes from, and the page with its workers and iframes. One value out of step is what stands out.
An agent working in one browser carries every task’s cookies and sign-ins into the next, and a page that tricks it can act on all of them. Each task, client or permitted account belongs in a profile of its own.
An agent that signs in again on every run looks nothing like a returning visitor and stops at every code prompt. A saved profile comes back signed in, with the same device as last time.
Use agents only where each site’s terms and the law allow it, and for accounts a site’s terms allow. Our acceptable use policy applies to agents the same as to people.
The criteria
We chose the criteria from what an agent builder has to decide: how the fingerprint is made, whether tasks stay apart, how the agent connects, what stops it doing damage, where the browser runs, what it costs to try, and whether the vendor shows its evidence. Each checkpoint is a question the vendor’s public pages either answer or don’t.
| Criterion | Why it matters for agents | Checkpoints |
|---|---|---|
| A fingerprint set in the engine | Values produced by the browser’s own code read as native in the page, its iframes and its workers. Values overridden by a script layered on top can be compared against those scopes. |
|
| An isolated profile per task | One task’s cookies and sign-ins should never be there for the next, and a returning task should find its session. |
|
| Interfaces an agent can use | Agents arrive over MCP; code arrives over an API, an SDK, or Playwright and Puppeteer. |
|
| Controls on what an agent may do | An agent that a page tricks should hold as little as possible: a key of its own, the sites it needs, and no passwords. |
|
| Runs on your own computer | Sessions, cookies and proxy credentials stay on a machine you control. |
|
| Free to start | You can try it with an agent before paying. |
|
| Evidence you can check | Dated results with a method can be repeated; adjectives can’t. |

Scoring. One point for each checkpoint a product’s own public pages state, 13 in all. “Not documented” scores nothing; it means the pages we read are silent, and the product may still do it. Products are ranked by score, and products with the same score share a rank, listed alphabetically. The criteria reflect what we think matters to agent builders; a reader who weighs them differently can re-rank from the table.

“Not documented” means the public pages we read on 13 Nov 2026 don’t state it, not that the product lacks it. Prices are each vendor’s lowest listed monthly price on that day, in US dollars, and change often: check the vendor’s pricing page. Numbers in brackets link to the sources.

Why Browz is first
Each reason is tied to one of the seven criteria and to a page where it can be checked.
The values a site reads are changed in the engine’s own code, so no script is added to the pages an agent visits, built-in functions stay native, and a page, its iframes and its workers read the same values. How that differs from a script layered on top. Four other products here document an engine-level approach too, and the table says so; what sets Browz apart is the rest of this list.
One call opens a session and gives the task a profile of its own: a throwaway one wiped when the task ends, or a returning one that keeps its sign-in, fingerprint and proxy for next time.
The MCP server ships inside the app and has page tools of its own (snapshot, act, wait, screenshot), over stdio or loopback HTTP. Agents in the cloud reach the same profiles through the remote server at mcp.gobrowz.com, a free public beta. Code uses the local REST API, the CLI, the TypeScript and Python SDKs, or Playwright, Puppeteer and Selenium over CDP.
This is where the public documentation differs most. Each agent gets a key of its own, limited to its scopes, its profiles and its allowed sites, rate-limited, logged on your computer and revocable at once. Stored sign-ins are typed by Browz itself, so the agent uses a password or code without reading it. When a site asks for a person, the agent pauses and hands the window to you.Browz is the only product here whose public pages state all four controls.
The browser an agent drives is the real profile on your Mac, Windows or Linux computer. Cookies, sessions and proxy credentials stay there, and sync between your computers is end-to-end encrypted.
The Free plan has 5 profiles and includes the local MCP server, API, CLI and SDKs, never metered. Paid plans start at $4.99 a month, with a 14-day refund on the first payment.
We publish what we measured, with dates: detector results on the anti-detect page, and an agent benchmark with its tasks and method. We also give away the fingerprint test we use, so the reader can run the same checks in any browser, ours included.
Check it yourself
A ranking written by one of the ranked is worth what the reader can verify. Three ways to do that, none of which needs an account with us.
Open our free browser fingerprint test in every browser you are considering, ours and theirs. It runs in the page and sends nothing. Read three checks first: Built-in functions untouched (a function replaced by a script no longer reads as native code), Page vs Web Worker and Page vs iframe (values changed by a page script often differ in those scopes), then No automation flags with your agent attached.
Download the JSON from one profile, run the test in a second profile, and paste the first file into Compare. Separate profiles should have different fingerprint IDs, and each should keep its ID after a restart.
In our agent benchmark, the same AI agent finished 46 of 50 public web tasks through the Browz MCP server and 38 of 50 through a plain browser MCP server (recorded 2 Nov 2026). The page lists the tasks, the model and how a run is scored. The detector results we publish for Browz are on the anti-detect page, with dates; open the same public test sites in a Browz profile to repeat them.
Our own result: on 13 Nov 2026, Browz 0.1.9 on macOS passed 15 of 15 consistency checks in our fingerprint test, headless and headed (the test’s JSON). On Windows and Linux the same test found no inconsistencies (Windows JSON, Linux JSON).
Then follow each product’s own sources below and check the cells that matter to you. A fingerprint test shows what a browser presents; your proxy, your agent’s behaviour and each site’s terms matter as well.
FAQ
On the thirteen checkpoints published on this page, Browz scores highest: 13 of 13 from its public pages, as read on 13 Nov 2026. We make Browz, so check the criteria and the sources rather than taking the ranking on trust. The right choice also depends on where you want the browser to run: on your own computer, or in a provider’s cloud.
An agent needs one when its tasks must stay apart from each other and from your own browser, and when the sites it visits should see one consistent, ordinary device from visit to visit. For reading public pages that never sign in, a plain browser is often enough. Use any of these tools only where a site’s terms and the law allow automated use.
Each product gets one point for every checkpoint its own public pages state, out of 13. We read each vendor’s site, docs, pricing page and public repositories on 13 Nov 2026 and linked every source. A feature that those pages don’t mention is shown as “Not documented” and scores nothing, so a product may do more than its score shows. Products with the same score share a rank.
Not for this page. The table reports what each vendor documents, which anyone can check from the links. To compare behaviour, run our free browser fingerprint test in each browser you are considering: it runs in the page, sends nothing, and reports whether built-in functions are native and whether the page, a worker and an iframe read the same values.
An injected script overrides JavaScript properties after the browser has started, which a page can find by inspecting the replaced functions or by reading the same value from a worker or an iframe. An engine-level change is made in the browser’s own code, so the value is native wherever it is read. The full explanation.
In Browz, CAPTCHAs always go to a person: the agent hands the window to you, you complete the step, and the agent carries on in the same session.
A cloud browser suits many short-lived sessions with nothing to install. A local browser keeps cookies, sessions and proxy credentials on a computer you control and lets a person step into the same window. Browz runs locally and adds a remote MCP endpoint, so cloud agents can still reach the profiles on your computer.
