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)

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:

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

Universal shadow DOM traversal

Playwright's built-in shadow DOM piercing

Playwright can pierce shadow DOM natively in some cases:

// 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

Common editor selectors

'[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)

Key insights for Reddit:

• - Mobile launchHuman() shows app redirect page — always use INLINECODE5
• Button click on "Log In" unreliable — keyboard.press('Enter') works
• INLINECODE7 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

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: INLINECODE10

reCAPTCHA v2 (checkbox/invisible)

Intercept and replace reCAPTCHA token in network requests

reCAPTCHA site keys (known)

Check balance

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

Network interception (intercept/modify/mock requests)

Common debugging techniques

Take screenshot when something fails

Dump all visible form elements

Check if login actually worked (don't trust URL)

Check current IP

Verify stealth fingerprint

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

Cloudflare checks these signals (in order of importance):

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

CODEBLOCK23

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)

Check Bright Data zone status:

• - POST blocked = KYC required → brightdata.com/cp/kyc
• 402 error = zone over quota or wrong zone name
• INLINECODE15 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: INLINECODE21
