Browserless Alternative? Human Browser Drives the Browser For You.

Two different shapes of the same problem

Browserless and Human Browser both put a real Chromium in the cloud. But they are built for different people, and picking the right one starts with being honest about which job you are doing.

Browserless is headless-browser infrastructure. You connect your own automation — Playwright, Puppeteer, or their BrowserQL query language — to a remote Chromium over a CDP/WebSocket endpoint, or you self-host the open-core Docker image on your own machines. It is a mature, developer-first product for teams that already write browser-driver code and want to run it at scale without operating the browser fleet themselves.

Human Browser is an AI-agent-native browser. Instead of shipping browser-driver code, you send a goal — "log into this dashboard and export the CSV" — to an A2A (v0.3) endpoint or call it as an MCP tool, and the agent plans and executes the clicks, types, scrolls and extractions for you. Residential IP, a 12-type CAPTCHA solver, a stealth-patched headful Chrome, persistent profiles and a live human-in-the-loop viewer are wired in by default, billed on one pay-as-you-go invoice.

If you are writing the automation yourself, Browserless is purpose-built for that. If you want an agent to do the driving and you do not want to assemble an anti-bot stack, that is what Human Browser is for.

The unit-accounting tax

Browserless prices in Units. One Unit is up to 30 seconds of browser time per connection; reconnects start a new connection. Residential proxy traffic is billed at 6 Units per MB and successful CAPTCHA solves at 10 Units each. Those Units come bundled into monthly subscription tiers — Free, Prototyping, Starter, Scale, Enterprise — where unused units reset at the end of each cycle and your concurrency ceiling is set by the plan.

None of this is hidden or unfair — it is a perfectly normal SaaS metering model, and for steady, predictable, high-volume headless workloads it can be very cost-effective. It is just accounting overhead that an indie builder or an early-stage agent team usually does not want to carry. (Always check the current per-plan unit rates on the Browserless pricing page — they set how a Unit converts to dollars.)

What you get with Human Browser

Human Browser collapses the stack and the accounting into one pay-as-you-go API.

Comparing the wider field, not just Browserless? We keep an honest, regularly updated comparison of the best cloud browsers for AI agents — Human Browser, Browserbase, Steel.dev, Browserless, ZenRows and more — and a focused head-to-head on Human Browser vs Browserbase.

Pricing model comparison

The exact dollar cost of a Browserless run depends on your plan's unit price and the round-up rules above, so we deliberately do not quote a single per-minute figure for them — check browserless.io/pricing for current rates. The structural difference is the takeaway: Human Browser bills flat, itemized, and only for what you use, with no plan to size and no units to reconcile.

When Browserless is the right choice

We are not going to pretend Browserless has no advantages. It has real ones — be honest about your needs.

• You need to self-host. If data residency or air-gapped infrastructure is a hard requirement, Browserless's open-core Docker image runs on your own machines. Human Browser is managed-only; this round goes to Browserless.
• You already write your own browser-driver code. If you have battle-tested Playwright/Puppeteer scripts and want a fast, scalable remote Chromium to point them at, that is exactly what Browserless is built for.
• You want BrowserQL or fine CDP control. Browserless ships a purpose-built query language and first-class CDP/session tooling. If your application is browser-infra-first rather than agent-first, that surface area matters.
• You run steady, high-volume, predictable headless workloads where a sized monthly plan and self-hosting can be more economical than per-usage cloud billing.

When Human Browser is the right choice

• You are building an AI agent and want it to drive a browser by describing goals, not by shipping and maintaining Playwright code.
• You are A2A- or MCP-first — your agent already speaks the protocol, and you want a browser reachable as another agent or as an MCP tool rather than as infrastructure to wire up.
• Your workload is CAPTCHA-heavy or stealth-heavy. Login flows behind Cloudflare, ad-platform dashboards, scraper-hostile SPAs. The bundled solver and stealth-patched Chrome pay for themselves immediately.
• You do not want a subscription or unit accounting. One bill — minutes, GB, solves, AI — pay-as-you-go, balance never expires, no plan ceiling to manage.
• You want a live viewer with real human takeover on every session, free, for the moments an agent needs a hand.
• You want sessions that get smarter over time via the per-site knowledge base.

Code example: Browserless CDP script vs Human Browser A2A

import { chromium } from 'playwright-core';
import { solveCaptcha } from './my-captcha-helper';

// Connect your code to a remote Chromium over CDP
const browser = await chromium.connectOverCDP(
  'wss://chrome.browserless.io?token=' + process.env.BL_TOKEN +
  '&proxy=residential'
);
const page = await browser.newPage();
await page.goto('https://target.com/login');

// You drive every step yourself
await page.fill('#email', process.env.USER);
await page.fill('#password', process.env.PASS);
if (await page.$('.cf-turnstile')) {
  await solveCaptcha(page);
}
await page.click('button[type=submit]');
// ...selectors, waits, extraction, retries — all yours...

const res = await fetch('https://agent.humanbrowser.cloud/a2a', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': 'Bearer ' + process.env.HB_TOKEN
  },
  body: JSON.stringify({
    jsonrpc: '2.0',
    id: 'login-1',
    method: 'tasks/send',
    params: {
      skill: 'login_and_scrape',
      message: 'Log into target.com, export CSV from /reports',
      country: 'gb',
      profile: 'reports-bot'
    }
  })
});
const { result } = await res.json();
// Residential IP, stealth, CAPTCHA, login, extraction all handled.
// result.artifacts contains the CSV.

The left side is the Browserless model: a remote browser plus the automation logic you own and maintain. The right side is the Human Browser model: a goal in, a result out. Neither is wrong — they are aimed at different builders.
