WebPerception runs the browser for you in the cloud

-----|------|

| Server (4GB RAM per browser) | $20-80/mo per instance |

| Proxy rotation | $50-500/mo |

| Browser management | Engineering time |

| Anti-detection updates | Ongoing maintenance |

| Failed requests (30-60%) | Wasted compute |

For 10,000 pages/day with headless browsers, expect to spend $200-800/month on infrastructure alone, plus significant engineering time.

The Alternative: Skip the Browser Entirely

What if you could get rendered, JavaScript-executed page content without running a browser?

import requests

# WebPerception runs the browser for you in the cloud
response = requests.get(
    "https://api.mantisapi.com/v1/scrape",
    params={
        "url": "https://javascript-heavy-site.com",
        "format": "markdown",
        "render": True
    },
    headers={"Authorization": f"Bearer {API_KEY}"}
)

content = response.json()["content"]
# Full JavaScript-rendered content, clean markdown, no browser to manage

What you get:

• JavaScript rendering (handled in the cloud)
• Anti-bot bypass (built-in)
• Clean content extraction (no CSS selectors)
• AI-powered structured data extraction
• Screenshots if you need them

What you don't need:

• Browser installation or updates
• Proxy infrastructure
• Stealth configurations
• Server capacity for browsers

When to Use Headless Browsers vs. API

Use headless browsers when:

• You need complex multi-step interactions (login → navigate → fill forms → submit)
• You're building browser automation (not just scraping)
• You need pixel-perfect screenshots with custom interactions
• You're scraping a handful of specific sites you control

Use an API when:

• You need data from many different websites
• You want zero infrastructure maintenance
• Anti-bot bypass matters
• You're building an AI agent that needs web data
• You care about cost-efficiency at scale

Getting Started

If headless browser scraping is giving you headaches — anti-bot blocks, memory issues, flaky tests — try the API approach first. WebPerception gives you 100 free calls/month to test with. No browser setup required.
