spider-client
Python SDK for Spider Cloud API
Decision gist · record as of 2026-08-14
Yes, if you need a managed web scraping solution with built-in anti-bot handling and LLM-ready output formatting. The SDK is actively maintained, has no known vulnerabilities, and low install friction. However, it requires a Spider Cloud account and API key—this is a client library for a paid service, not a standalone scraper. Suitable for production use when the service cost aligns with your scraping volume.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a Spider Cloud API key (obtain from spider.cloud); set as SPIDER_API_KEY environment variable or pass directly to Spider class.
- Low friction installation with five runtime dependencies (requests, ijson, tenacity, aiohttp, spider-browser).
- Package is actively maintained with recent releases; last commit on 2026-07-19 and version 0.1.93 released 2026-07-18.

What it is and what it does
spider-client is a Python SDK that wraps the Spider Cloud API, a managed web scraping and crawling service. It provides methods to scrape individual URLs, crawl entire websites, extract links, capture screenshots, transform HTML to markdown, and bypass anti-bot protections. The SDK also includes AI-powered methods (requiring a separate subscription) for guided scraping and crawling using natural language prompts, plus an Unlimited plan tier that bills by concurrency seats rather than per-request credits.
The package handles the HTTP communication with Spider Cloud's backend, manages streaming responses, supports multiple output formats (JSON, CSV, XML, JSONL), and formats scraped content for compatibility with language models. It relies on requests for HTTP calls, ijson for streaming JSON parsing, tenacity for retry logic, aiohttp for async operations, and spider-browser for browser automation features.
Use it for
- Scrape product listings or pricing data from e-commerce sites and format for LLM ingestion.
- Crawl documentation sites or knowledge bases to build training datasets for AI models.
- Extract all links from a website for SEO analysis or site mapping.
- Bypass anti-bot protections on protected sites using the unblocker feature with AI extraction.
- Automate screenshot capture of web pages for visual monitoring or testing.
- Stream large crawl results in chunks to handle websites with hundreds or thousands of pages.
