Anti-detection Scrapy middleware — proxy routing and browser rendering for web scraping

scrapy-calyprium

Anti-detection Scrapy middleware for web scraping — proxy routing and stealth browser rendering powered by Calyprium.

Install

pip install scrapy-calyprium

Quick Start

# settings.py
import scrapy_calyprium

scrapy_calyprium.configure(api_key="clp_your_key_here")

This auto-configures:

• VeilProxyMiddleware — routes requests through rotating proxies with TLS fingerprinting
• MimicBrowserMiddleware — renders JavaScript pages with stealth browser instances
• S3 feed storage — write spider output to Calyprium storage using Scrapy's built-in S3FeedStorage

Usage

Automatic Configuration (recommended)

# settings.py
import scrapy_calyprium

scrapy_calyprium.configure(
    api_key="clp_your_key_here",
    mimic_stealth_level="maximum",  # basic, moderate, maximum
)

Manual Configuration

# settings.py
DOWNLOADER_MIDDLEWARES = {
    "scrapy_calyprium.VeilProxyMiddleware": 100,
    "scrapy_calyprium.MimicBrowserMiddleware": 200,
}

CALYPRIUM_API_KEY = "clp_your_key_here"
VEIL_USER_ID = "your-user-id"

Saving Output to Calyprium Storage

Spider output is saved to Calyprium's S3-compatible storage using Scrapy's built-in feed export:

# settings.py
import scrapy_calyprium

scrapy_calyprium.configure(api_key="clp_your_key_here")

FEEDS = {
    "s3://calyprium/my-spider/%(time)s.jl": {
        "format": "jsonlines",
    },
}

The S3 credentials are auto-configured by configure() — no additional setup needed.

Browser Rendering

Mark requests that need JavaScript rendering:

import scrapy

class MySpider(scrapy.Spider):
    name = "example"

    def start_requests(self):
        # Regular request (proxy only)
        yield scrapy.Request("https://example.com")

        # Browser-rendered request
        yield scrapy.Request(
            "https://example.com/spa",
            meta={"mimic": True},
        )

Authentication

All middleware requires a valid API key. Set it via:

1. scrapy_calyprium.configure(api_key="clp_...")
2. CALYPRIUM_API_KEY environment variable
