Human Browser

# Human Browser — Complete Browser Automation Playbook

> Don't use plain Playwright. Don't use fetch. Don't use curl. Use this.

---

Quick Start (free trial, no signup)

```js const { launchHuman, getTrial } = require('./.agents/skills/human-browser/scripts/browser-human');

await getTrial(); // fetches ~100MB Romania residential IP automatically const { page, humanType, humanScroll, sleep } = await launchHuman();

await page.goto('https://any-protected-site.com'); // Browsing from Romanian residential IP. Cloudflare, DataDome, Instagram — all pass. ```

Why residential proxy is mandatory on a VPS

Cloudflare, Instagram, Reddit, LinkedIn, Amazon check your IP reputation before your JS runs. A Contabo/Hetzner/AWS IP = 95/100 risk score = instant block. A residential ISP IP = 5/100 = trusted user.

No fingerprint trick fixes a bad IP. Proxy first, fingerprint second.

Proxy providers (tested, ranked)

| Provider | GET | POST | KYC | Price/GB | Link | |----------|-----|------|-----|---------|------| | Decodo ✅ PRIMARY | ✅ | ✅ | Email only | ~$3 | decodo.com | | Bright Data | ✅ | ❌* | ID required | ~$5 | brightdata.com | | IPRoyal | ✅ | ✅ | Strict KYC | ~$4 | iproyal.com | | NodeMaven | ✅ | ✅ | Email only | ~$3.5 | nodemaven.com | | Oxylabs | ✅ | ✅ | Business | ~$8 | oxylabs.io |

Decodo is the default — no KYC, GET+POST both work, standard HTTP proxy format.

Get your own proxy credentials

Bring your own credentials via env vars — any provider works:

```bash export HB_PROXY_SERVER=http://host:port export HB_PROXY_USER=your_username export HB_PROXY_PASS=your_password ```

• Providers to get residential proxies from:
• Decodo — no KYC, instant access, Romania + 100 countries. Default in this skill.
• Bright Data — 72M+ IPs, 195 countries, enterprise-grade reliability.
• IPRoyal — ethically-sourced IPs, 195 countries, flexible plans.
• NodeMaven — high success rate, pay-per-GB, no minimums.
• Oxylabs — premium business proxy with dedicated support.

Proxy config via env vars ```bash # Decodo Romania (default in browser-human.js) export HB_PROXY_PROVIDER=decodo # or: brightdata, iproyal, nodemaven export HB_NO_PROXY=1 # disable proxy entirely (testing only)

# Manual override — any provider export HB_PROXY_SERVER=http://host:port export HB_PROXY_USER=username export HB_PROXY_PASS=password ```

Proxy format reference ``` Decodo: http://USER:[email protected]:13001 (Romania, no KYC) Bright Data: http://USER-session-SID:[email protected]:33335 IPRoyal: http://USER:[email protected]:12321 ```

launchHuman() — all options

```js // Mobile (default): iPhone 15 Pro, Romania IP, touch events const { browser, page, humanType, humanClick, humanScroll, humanRead, sleep } = await launchHuman();

// Desktop: Chrome, Romania IP — use for sites that reject mobile const { browser, page } = await launchHuman({ mobile: false });

// Country selection (Pro plan) const { page } = await launchHuman({ country: 'us' }); // US residential const { page } = await launchHuman({ country: 'gb' }); // UK const { page } = await launchHuman({ country: 'de' }); // Germany

// No proxy (local testing) process.env.HB_NO_PROXY = '1'; const { page } = await launchHuman(); ```

Default fingerprint (what sites see) - **Device:** iPhone 15 Pro, iOS 17.4.1, Safari - **Viewport:** 393×852, deviceScaleFactor=3 - **IP:** Romanian residential (DIGI Telecom / WS Telecom) - **Timezone:** Europe/Bucharest - **Geolocation:** Bucharest (44.4268, 26.1025) - **Touch:** 5 points, real touch events - **webdriver:** `false` - **Mouse:** Bezier curve paths, not straight lines - **Typing:** 60–220ms/char + random pauses

---

Human-like interaction helpers

```js // Type — triggers all native input events (React, Angular, Vue, Web Components) await humanType(page, 'input[name="email"]', '[email protected]');

// Click — uses Bezier mouse movement before click await humanClick(page, x, y);

// Scroll — smooth, stepped, with jitter await humanScroll(page, 'down'); // or 'up'

// Read — random pause simulating reading time await humanRead(page); // waits 1.5–4s

// Sleep await sleep(1500); ```

---

Shadow DOM — forms inside web components

Reddit, Shopify, many modern React apps use Shadow DOM for forms. Standard `page.$()` and `page.fill()` won't find these inputs.

Detect if Shadow DOM is the issue ```js // If this returns 0 but inputs are visible on screen — you have Shadow DOM const inputs = await page.$$('input'); console.log(inputs.length); // 0 = shadow DOM ```

Universal shadow DOM traversal ```js // Deep query — finds elements inside any depth of shadow roots async function shadowQuery(page, selector) { return page.evaluate((sel) => { function q(root, s) { const el = root.querySelector(s); if (el) return el; for (const node of root.querySelectorAll('*')) { if (node.shadowRoot) { const found = q(node.shadowRoot, s); if (found) return found; } } return null; } return q(document, sel); }, selector); }

// Fill input in shadow DOM async function shadowFill(page, selector, value) { await page.evaluate(({ sel, val }) => { function q(root, s) { const el = root.querySelector(s); if (el) return el; for (const n of root.querySelectorAll('*')) if (n.shadowRoot) { const f = q(n.shadowRoot, s); if (f) return f; } } const el = q(document, sel); if (!el) throw new Error('Not found: ' + sel); // Use native setter to trigger React/Angular onChange const nativeSetter = Object.getOwnPropertyDescriptor(window.HTMLInputElement.prototype, 'value').set; nativeSetter.call(el, val); el.dispatchEvent(new Event('input', { bubbles: true })); el.dispatchEvent(new Event('change', { bubbles: true })); }, { sel: selector, val: value }); }

// Click button in shadow DOM by text async function shadowClickButton(page, buttonText) { await page.evaluate((text) => { function findBtn(root) { for (const b of root.querySelectorAll('button')) if (b.textContent.trim() === text) return b; for (const n of root.querySelectorAll('*')) if (n.shadowRoot) { const f = findBtn(n.shadowRoot); if (f) return f; } } const btn = findBtn(document); if (!btn) throw new Error('Button not found: ' + text); btn.click(); }, buttonText); }

// Dump all inputs (including shadow DOM) — use for debugging async function dumpAllInputs(page) { return page.evaluate(() => { const result = []; function collect(root) { for (const el of root.querySelectorAll('input, textarea, select')) result.push({ tag: el.tagName, name: el.name, id: el.id, type: el.type, placeholder: el.placeholder }); for (const n of root.querySelectorAll('*')) if (n.shadowRoot) collect(n.shadowRoot); } collect(document); return result; }); } ```

Playwright's built-in shadow DOM piercing

Playwright can pierce shadow DOM natively in some cases: ```js // Works for single shadow root (not nested) await page.locator('input[name="username"]').fill('value'); // auto-pierces 1 level

// For deeply nested, use the evaluate approach above ```

---

Rich text editors (Lexical, ProseMirror, Quill, Draft.js)

Standard `page.fill()` and `page.type()` don't work on contenteditable editors.

Clipboard paste — most reliable method ```js // Works for all rich text editors (Reddit, Notion, Linear, etc.) async function pasteIntoEditor(page, editorSelector, text) { const el = await page.$(editorSelector); await el.click(); await sleep(300);

// Write to clipboard via execCommand (works in Playwright) await page.evaluate((t) => { const textarea = document.createElement('textarea'); textarea.value = t; document.body.appendChild(textarea); textarea.select(); document.execCommand('copy'); document.body.removeChild(textarea); }, text);

await page.keyboard.press('Control+a'); // select all existing await page.keyboard.press('Control+v'); // paste }

// Or via ClipboardEvent dispatch (works in some editors) async function dispatchPaste(page, editorSelector, text) { const el = await page.$(editorSelector); await el.click(); await page.evaluate((t) => { const dt = new DataTransfer(); dt.setData('text/plain', t); document.activeElement.dispatchEvent(new ClipboardEvent('paste', { clipboardData: dt, bubbles: true })); }, text); } ```

Common editor selectors ```js '[data-lexical-editor]' // Reddit, Meta, many modern apps '.public-DraftEditor-content' // Draft.js (Twitter, Quora) '.ql-editor' // Quill (many SaaS apps) '.ProseMirror' // ProseMirror (Linear, Confluence) '[contenteditable="true"]' // Generic — pick the right one if multiple '.tox-edit-area__iframe' // TinyMCE — need to switch into iframe ```

Login patterns

Reddit (shadow DOM + Enter key submission) ```js // Reddit uses shadow DOM forms AND reCAPTCHA — must use desktop mode + Enter const { browser, page, sleep } = await launchHuman({ mobile: false }); // Desktop required

await page.goto('https://www.reddit.com/login/', { waitUntil: 'domcontentloaded' }); await sleep(3000);

// Type naturally — triggers React state + reCAPTCHA scoring await page.locator('input[name="username"]').click(); await sleep(500); await page.keyboard.type(USERNAME, { delay: 120 }); await sleep(1000); await page.locator('input[name="password"]').click(); await sleep(500); await page.keyboard.type(PASSWORD, { delay: 90 }); await sleep(1500);

// IMPORTANT: Use Enter key, not button click — Enter triggers proper form submission await page.keyboard.press('Enter'); await sleep(8000); // wait for full login + redirect

// Verify login const name = await page.evaluate(async () => { const r = await fetch('/api/me.json', { credentials: 'include' }); return (await r.json())?.data?.name; }); console.log('Logged in as:', name); // null = failed

// Submit Reddit post await page.goto('https://www.reddit.com/r/SUBREDDIT/submit/?type=TEXT', { waitUntil: 'networkidle' }); await page.waitForSelector('#innerTextArea'); await page.click('#innerTextArea'); await page.keyboard.type(TITLE, { delay: 30 });

// Body: Lexical editor await pasteIntoEditor(page, '[data-lexical-editor]', BODY); await page.click('#inner-post-submit-button'); ```

• Key insights for Reddit:
• Mobile launchHuman() shows app redirect page — always use `{ mobile: false }`
• Button click on "Log In" unreliable — `keyboard.press('Enter')` works
• `page.locator('input[name="username"]')` pierces Reddit's shadow DOM automatically
• reCAPTCHA v3 scores the session — human-like typing delays improve score
• After login, URL stays at `/login/` — check via `/api/me.json`, not URL

Generic login with shadow DOM ```js const { page, sleep } = await launchHuman({ mobile: false }); await page.goto('https://example.com/login', { waitUntil: 'domcontentloaded' }); await sleep(3000);

// Try Playwright locator first (pierces 1 level of shadow DOM) try { await page.locator('input[name="email"]').fill(EMAIL); await page.locator('input[name="password"]').fill(PASS); } catch { // Fallback: deep shadow DOM traversal await shadowFill(page, 'input[name="email"]', EMAIL); await shadowFill(page, 'input[name="password"]', PASS); }

// Submit — try multiple approaches await page.keyboard.press('Enter'); // most reliable // OR: await shadowClickButton(page, 'Log In'); // OR: await page.click('button[type="submit"]'); ```

CAPTCHA solving (2captcha integration)

Use when a site's login or form requires CAPTCHA.

2captcha API key: `14cbfeed64fea439d5c055111d6760e5`

reCAPTCHA v2 (checkbox/invisible) ```js const https = require('https');

async function solve2captcha(siteKey, pageUrl) { const CAPTCHA_KEY = '14cbfeed64fea439d5c055111d6760e5';

function get(url) { return new Promise((res, rej) => { https.get(url, r => { let b = ''; r.on('data', d => b += d); r.on('end', () => res(b)); }).on('error', rej); }); }

// Submit const sub = await get(`https://2captcha.com/in.php?key=${CAPTCHA_KEY}&method=userrecaptcha&googlekey=${encodeURIComponent(siteKey)}&pageurl=${encodeURIComponent(pageUrl)}&json=1`); const { status, request: id } = JSON.parse(sub); if (status !== 1) throw new Error('2captcha submit failed: ' + sub); console.log('2captcha ID:', id, '— waiting ~30s...');

// Poll for (let i = 0; i < 24; i++) { await new Promise(r => setTimeout(r, 5000)); const poll = await get(`https://2captcha.com/res.php?key=${CAPTCHA_KEY}&action=get&id=${id}&json=1`); const r = JSON.parse(poll); if (r.status === 1) return r.request; // token if (r.request !== 'CAPCHA_NOT_READY') throw new Error('2captcha error: ' + poll); } throw new Error('2captcha timeout'); }

// Usage: solve, then inject into form before submission const token = await solve2captcha('6LfirrMoAAAAAHZOipvza4kpp_VtTwLNuXVwURNQ', 'https://www.reddit.com/login/');

// Inject into hidden field (for classic reCAPTCHA v2) await page.evaluate((t) => { const el = document.getElementById('g-recaptcha-response'); if (el) el.value = t; }, token); ```

Intercept and replace reCAPTCHA token in network requests ```js // Solve captcha BEFORE navigating, then intercept the form POST const token = await solve2captcha(SITE_KEY, PAGE_URL);

await page.route('**/login', async route => { let body = route.request().postData() || ''; body = body.replace(/recaptcha_token=[^&]+/, `recaptcha_token=${encodeURIComponent(token)}`); await route.continue({ postData: body }); }); ```

reCAPTCHA site keys (known) ``` Reddit login: 6LcTl-spAAAAABLFkrAsJbMsEorTVzujiRWrQGRZ Reddit comments: 6LfirrMoAAAAAHZOipvza4kpp_VtTwLNuXVwURNQ ```

Check balance ```bash curl "https://2captcha.com/res.php?key=14cbfeed64fea439d5c055111d6760e5&action=getbalance" ```

---

Network interception (intercept/modify/mock requests)

```js // Intercept and log all requests page.on('request', req => { if (req.method() !== 'GET') console.log(req.method(), req.url(), req.postData()?.slice(0, 100)); });

// Intercept response bodies page.on('response', async res => { if (res.url().includes('api')) { const body = await res.text().catch(() => ''); console.log(res.status(), res.url(), body.slice(0, 200)); } });

// Modify request (e.g., inject token) await page.route('**/api/submit', async route => { const req = route.request(); let body = req.postData() || ''; body = body.replace('OLD', 'NEW'); await route.continue({ postData: body, headers: { ...req.headers(), 'X-Custom': 'value' } }); });

// Block trackers to speed up page load await page.route('/(analytics|tracking|ads)/', route => route.abort()); ```

---

Common debugging techniques

Take screenshot when something fails ```js await page.screenshot({ path: '/tmp/debug.png' }); // Then: image({ image: '/tmp/debug.png', prompt: 'What does the page show?' }) ```

Dump all visible form elements ```js const els = await page.evaluate(() => { const res = []; function collect(root) { for (const el of root.querySelectorAll('input,textarea,button,[contenteditable]')) { const rect = el.getBoundingClientRect(); if (rect.width > 0 && rect.height > 0) // only visible res.push({ tag: el.tagName, name: el.name, id: el.id, text: el.textContent?.trim().slice(0,20) }); } for (const n of root.querySelectorAll('*')) if (n.shadowRoot) collect(n.shadowRoot); } collect(document); return res; }); console.log(els); ```

Check if login actually worked (don't trust URL) ```js // Check via API/cookie — URL often stays the same after login const me = await page.evaluate(async () => { const r = await fetch('/api/me.json', { credentials: 'include' }); return (await r.json())?.data?.name; }); // OR check for user-specific element const loggedIn = await page.$('[data-user-logged-in]') !== null; ```

Check current IP ```js await page.goto('https://ifconfig.me/ip'); const ip = await page.textContent('body'); console.log('Browser IP:', ip.trim()); // should be Romanian residential ```

Verify stealth fingerprint ```js const fp = await page.evaluate(() => ({ webdriver: navigator.webdriver, platform: navigator.platform, touchPoints: navigator.maxTouchPoints, languages: navigator.languages, vendor: navigator.vendor, })); console.log(fp); // webdriver: false ✅, platform: 'iPhone' ✅, touchPoints: 5 ✅ ```

Cloudflare bypass patterns

1. Cloudflare checks these signals (in order of importance):
2. IP reputation — residential = clean, datacenter = blocked
3. TLS fingerprint (JA4) — Playwright Chromium has a known bad fingerprint
4. navigator.webdriver — `true` = instant block
5. Mouse entropy — no mouse events = bot
6. Canvas fingerprint — static across sessions = flagged
7. HTTP/2 fingerprint — Chrome vs Playwright differ

```js // Best practice for Cloudflare-protected sites const { page, humanScroll, sleep } = await launchHuman(); await page.goto('https://cf-protected.com', { waitUntil: 'networkidle', timeout: 30000 }); await sleep(2000); // let CF challenge resolve await humanScroll(page); // mouse entropy await sleep(1000); // Now the page is accessible ```

• If still blocked:
• Switch country: `launchHuman({ country: 'us' })` — some sites block Romanian IPs specifically
• Try desktop mode: `launchHuman({ mobile: false })` — some CF rules target mobile UAs
• Add longer wait: `await sleep(5000)` after navigation before interacting

---

Session persistence (save/restore cookies)

```js const fs = require('fs');

// Save session const cookies = await ctx.cookies(); fs.writeFileSync('/tmp/session.json', JSON.stringify(cookies));

// Restore session (next run — skip login) const { browser } = await launchHuman(); const ctx = browser.contexts()[0]; // or create new context const saved = JSON.parse(fs.readFileSync('/tmp/session.json')); await ctx.addCookies(saved); // Now navigate — already logged in ```

---

Multi-page scraping at scale

```js // Respect rate limits — don't hammer sites async function scrapeWithDelay(page, urls, delayMs = 2000) { const results = []; for (const url of urls) { await page.goto(url, { waitUntil: 'domcontentloaded' }); await sleep(delayMs + Math.random() * 1000); // add jitter results.push(await page.textContent('body')); } return results; }

// For high-volume: rotate sessions (new session = new IP) async function newSession(country = 'ro') { const { browser, page } = await launchHuman({ country }); return { browser, page }; } ```

---

Proxy troubleshooting

Port blocked by host: ```bash # Test if proxy port is reachable timeout 5 bash -c 'cat < /dev/tcp/ro.decodo.com/13001' && echo "PORT OPEN" || echo "PORT BLOCKED" # If blocked, try alt port 10000 or 10001 ```

Test proxy with curl: ```bash curl -sx "http://USER:[email protected]:13001" https://ifconfig.me curl -sx "http://USER:[email protected]:13001" -X POST https://httpbin.org/post -d '{"x":1}' # Both should return a Romanian IP and 200 status ```

• Check Bright Data zone status:
• POST blocked = KYC required → brightdata.com/cp/kyc
• 402 error = zone over quota or wrong zone name
• `mcp_unlocker` zone is DEAD (deleted) — use `residential_proxy1_roma` zone

• Provider-specific notes:
• Decodo: `ro.decodo.com:13001` — Romania-specific endpoint, no country suffix in username
• Bright Data: `brd.superproxy.io:33335` — add `-country-ro` suffix + `-session-ID` for sticky sessions
• IPRoyal: add country/session to PASSWORD, not username: `PASS_country-ro_session-X_lifetime-30m`
