SurveyJS comprises a collection of four open-source JavaScript libraries that provide the advantages of a customized, in-house survey application while significantly minimizing the time and resources required for deployment. These libraries function independently of specific server code or database needs, allowing for seamless integration with well-known JavaScript frameworks such as React, Angular, Vue.js, jQuery, Knockout, and others. They are built to interact with any server capable of processing JSON requests, thereby ensuring compatibility with a wide range of server setups and databases.
This product suite includes:
- An open-source library licensed under MIT that facilitates the rendering of dynamic JSON-based forms within your web application and captures user responses.
- A self-hosted form builder featuring drag-and-drop functionality, an integrated CSS theme editor, and a graphical user interface for setting conditional rules; it also generates JSON definitions of your forms in real time.
- A PDF Generator library that allows for the conversion of SurveyJS surveys and forms into PDF files directly in the browser.
- The Dashboard library, which enhances survey data analysis through interactive and customizable charts and tables.

Apify offers a comprehensive platform for web scraping, browser automation, and data extraction at scale. The platform combines managed cloud infrastructure with a marketplace of over 10,000 ready-to-use automation tools called Actors, making it suitable for both developers building custom solutions and business users seeking turnkey data collection.
Actors are serverless cloud programs that handle the technical complexities of modern web scraping: proxy rotation, CAPTCHA solving, JavaScript rendering, and headless browser management. Users can deploy pre-built Actors for popular use cases like scraping Amazon product data, extracting Google Maps listings, collecting social media content, or monitoring competitor pricing. For specialized needs, developers can build custom Actors using JavaScript, Python, or Crawlee, Apify's open-source web crawling library.
The platform operates a developer marketplace where programmers publish and monetize their automation tools. Apify manages infrastructure, usage tracking, and monthly payouts, creating a revenue stream for thousands of active contributors.
Enterprise features include 99.95% uptime SLA, SOC2 Type II certification, and full GDPR and CCPA compliance. The platform integrates with workflow automation tools like Zapier, Make, and n8n, supports LangChain for AI applications, and provides an MCP server that allows AI assistants to dynamically discover and execute Actors.

Preact
Preact provides a streamlined Virtual DOM interface that operates above the actual DOM, utilizing stable platform features while skillfully handling event listeners and ensuring compatibility with various libraries. In contrast to numerous UI frameworks that can bloat the JavaScript size of applications, Preact distinguishes itself by being exceedingly lightweight, meaning that the majority of an application's JavaScript consists of the developer's own code. This leads to reduced JavaScript that must be downloaded, parsed, and executed, enabling developers to concentrate on crafting customized user experiences without the hassle of navigating a heavy framework. In addition to its minimal size, Preact is celebrated for being one of the quickest Virtual DOM libraries available, thanks to its efficient and reliable diffing algorithm. The library enhances performance by automatically batching updates, and its development team works closely with browser engineers to optimize efficiency further. By using Preact, developers are afforded both speed and simplicity in their projects, which significantly contributes to an improved overall user experience. Furthermore, this makes Preact an attractive option for developers seeking a balance between performance and minimalism in their applications.
