Features and specs

What each product offers, as listed by its team.

Scrapy 6 features
useString.ai 0 features
  • Efficiency
    Scrapy is designed to be efficient and robust, capable of handling multiple tasks simultaneously and scraping large websites in a fast and reliable manner.
  • Built-in Tooling
    Scrapy comes with built-in tools for handling common tasks such as following links, extracting data using XPath and CSS, and exporting data in a variety of formats.
  • Customization
    Scrapy offers extensive customization options, allowing users to build complex spiders and modify their behavior through middleware and pipelines.
  • Python Integration
    Being a Python framework, Scrapy integrates seamlessly with the Python ecosystem, enabling the use of libraries like Pandas, NumPy, and others to process and analyze scraped data.
  • Community Support
    Scrapy has a large and active community, providing extensive documentation, tutorials, and third-party extensions to enhance functionality.
  • Asynchronous Processing
    Scrapy’s asynchronous processing model enhances performance by allowing multiple concurrent requests, reducing the time required for crawling sites.

Possible disadvantages

  • Steep Learning Curve
    For beginners, Scrapy's comprehensive feature set and the need for understanding concepts like XPath and CSS selectors can be challenging.
  • Resource Intensive
    Scrapy can be resource-intensive, potentially consuming significant memory and CPU, which can be problematic for scraping very large websites or running multiple spiders simultaneously.
  • Debugging Complexity
    Debugging Scrapy projects can be complex due to its asynchronous nature and the multiple layers of middleware and pipelines that need to be understood.
  • Overhead for Small Projects
    For simple or small-scale scraping tasks, the overhead of setting up and configuring a Scrapy project might be excessive, with simpler alternatives being more suitable.
  • Limited JavaScript Support
    Scrapy's out-of-the-box support for JavaScript-heavy websites is limited, requiring additional tools like Splash or Selenium, which can complicate the setup.
  • Dependency Management
    Managing Scrapy's dependencies and compatibility with other Python packages can sometimes be challenging, leading to potential conflicts and maintenance overhead.

Questions & Answers

As answered by people managing Scrapy and useString.ai.

What's the story behind your product?

useString.ai's answer:

String is a New York company building web-data infrastructure, turning the messy public web into accurate, usable data. Web Access is the part that actually gets pages back from sites that block other tools. It’s available as a standalone API and a hosted MCP server.

What makes your product unique?

useString.ai's answer:

It gets through sites that block other scrapers and only bills requests that succeed. In an open benchmark of 17 scraping APIs on 100 bot-protected sites, String had the highest success rate at 98.6%, and the method and raw data are public. It picks the proxy and rendering method for each page itself, so developers don’t manage proxies or retries.

Why should a person choose your product over its competitors?

useString.ai's answer:

The best reason is reliability on hard sites: highest success rate in our open benchmark, and blocked requests aren’t billed. There’s nothing to configure, since proxies, rendering and captcha handling are chosen automatically. It returns clean Markdown, HTML or JSON, also offers web search and site mapping, and has a hosted MCP server for agents in Claude and Cursor. Pricing is public, and new accounts get $5 of free credit (about 20,000 fetches), no card needed.

How would you describe the primary audience of your product?

useString.ai's answer:

Developers and data teams building AI agents, data products and pipelines that need live web data, especially from sites with strong bot protection. Typical uses are alternative data, pricing and inventory monitoring, talent and job data, real estate listings, and giving AI agents web access.

Which are the primary technologies used for building your product?

useString.ai's answer:

The service runs on managed cloud browsers and a proxy network, with automatic routing per request. The MCP server is open source and written in TypeScript. It exposes a REST API and an MCP endpoint, with SDK-free access from curl, Python and Node.

Who are some of the biggest customers of your product?

useString.ai's answer:

YipitData Revelio Labs DataWeave Sachem Head Canary Data Pararius Appsmith
