Questions & Answers

As answered by people managing StackMail and Human Browser Cloud.

What makes your product unique?

Human Browser Cloud's answer:

Three things competitors don't ship together: 1) Real Chromium on residential IPs — not stealth-headless. The agent loads pages that Browserbase / browser-use / Playwright crash on (Cloudflare Turnstile, hCaptcha, DataDome, PerimeterX press-and-hold). 2) MCP and A2A 1.0 native, side-by-side. Drop into Claude Desktop or any A2A-speaking host without glue code — most browser-clouds only ship REST. 3) A live session viewer URL you can hand to your end-user. Show them their agent working in their tab; they don't need an account. Powers consumer-grade AI products, not just dev tools.

Plus an ask_human primitive: when the agent hits 2FA or a captcha you don't want to auto-solve, it pauses and the operator answers via Telegram or your app. No more retries hoping a model guesses right.

Why should a person choose your product over its competitors?

Human Browser Cloud's answer:

  • Cheaper. $0.05/task pay-per-task, no upfront minimum. Browserbase's lowest tier is $0.10+/min and reserves capacity you may not use.
  • Handles the bot walls competitors crash on. Cloudflare, hCaptcha, reCAPTCHA, DataDome, PerimeterX — built-in solver, billed only when triggered.
  • MCP + A2A out of the box. Drop into Claude Computer Use, browser-use, LangGraph, Cursor in one line.
  • npm + GitHub for the client skill. Pin a version, audit the code, or fork it.
  • End-user-friendly live viewer (not a dev tool). Browserbase shows you the dev frame; we show your customer "AI is working on it…" in their tab.

How would you describe the primary audience of your product?

Human Browser Cloud's answer:

  • AI agent builders shipping production features that need to actually finish a task on the open web (Claude Computer Use, browser-use, LangChain, Vercel AI SDK users).
  • AI-native startups building consumer agents — form-fillers, comparison shoppers, lead generation, account ops, customer-portal scrapers.
  • Scraping teams priced out of Browserbase or blocked by Cloudflare with headless setups.
  • Solo devs / vibe coders who want MCP-compatible browser tool that works with Claude Desktop in 30 seconds.

What's the story behind your product?

Human Browser Cloud's answer:

The founder first tried OpenClaw in January 2026 and didn't get the point of it, until he started using Relay — the browser-agent integration — and the value finally clicked. Real AI agents on the open web were possible.

But just as fast, the limit showed up: the moment a session hit a captcha or a Cloudflare wall, the agent stopped, retried in circles, and died. Autonomous wasn't really autonomous if every bot-detection page required a human. That's where the idea for humanbrowser was born — a browser built specifically for AI agents that not only gets past the bot walls, but learns from every failed session and feeds the recipe back into the next one.

It started as @virixlabs/humanbrowser, an npm skill anyone could drop into Claude Code or a custom agent. The cloud version came right after — every user asked the same question: "okay this works on my laptop, where do I run it 24/7 with residential IPs and a viewer my customer can watch?"

The product goal: AI-native companies should never have to think about the browser layer. You bring the agent — humanbrowser brings the browser, the IPs, the captcha solver, the live viewer, the MCP/A2A protocols, and a self-learning loop that quietly gets better every time something fails.

Which are the primary technologies used for building your product?

Human Browser Cloud's answer:

  • Real Chromium
  • Node.js + Python
  • Сustom CDP injectors for fingerprint and behavioural input
  • A2A 1.0 protocol server, MCP server, REST API
  • Residential proxy pool 190+ Countries
  • LLM backends: OpenAI gpt direct, cross-provider fallback, Anthropic Claude, DeepSeek
  • Postmortem self-learning loop: every failed session is auto-analysed and the recipe is fed back into the agent's action rules
