ScreenshotMAX is a fast, reliable API that lets developers capture website screenshots, generate PDFs from HTML, record animated screencasts, and scrape web data: all with a single, unified interface.

Built by a developer, for developers, ScreenshotMAX eliminates the need to manage headless browsers, deal with flaky rendering, or write complex Puppeteer scripts. It handles the hard parts, so you can focus on your app.

Key Features - Full-page & viewport screenshots: Including lazy-loaded content and dynamic pages. - HTML to PDF rendering: Turn any page or HTML string into a clean, production-ready PDF. - Animated video rendering: Record scrolling or dynamic elements as MP4. - Annoyance blocking: Remove cookie banners, ads, and GDPR popups by default. - Scheduled tasks: Automate recurring jobs: no cron or infrastructure needed. - Fast, scalable & secure: Runs on Google Cloud + Cloudflare, with Redis for rate limiting.

SockJS features and specs

  • Cross-browser Compatibility
    SockJS provides a consistent WebSocket-like API that works across all modern browsers, including fallback options for older browsers that don't support WebSockets.
  • Fallback Options
    SockJS automatically uses the best-available transport method, such as JSONP, XHR streaming, or XHR polling, ensuring connectivity even in challenging network environments.
  • Reliability
    By offering multiple transport methods, SockJS provides reliable real-time communication even when WebSocket connections might be unstable or unsupported.
  • Ease of Use
    SockJS abstracts the complexity of managing various transport protocols, allowing developers to focus on implementing application logic rather than handling connection details.
  • Server Support
    SockJS is supported by several server-side implementations in different programming languages, enabling flexibility in choosing backend technologies.

Possible disadvantages of SockJS

  • Overhead
    The additional abstraction layer and fallback mechanisms may introduce some overhead compared to using native WebSockets directly, impacting performance to some extent.
  • Configuration Complexity
    Setting up SockJS with proper fallback handling and configuring the server-side components might be more complex than using native WebSockets, especially for simple use cases.
  • Less Control
    Developers have less control over the specific transport protocols being used, which might be a disadvantage in scenarios where such control is necessary for optimization or monitoring purposes.
  • Potential Latency
    Using fallback transports like polling can introduce higher latency compared to native WebSocket connections, which might not be suitable for highly time-sensitive applications.
  • Project Maintenance
    As an open-source project, SockJS relies on community support for maintenance and updates. This could pose a risk if development and support decline over time.

What makes your product unique?

ScreenshotMAX's answer

ScreenshotMAX combines powerful rendering (screenshot, video, PDF) with automation features like scheduled tasks and annoyance blocking. It’s built for developers who need reliable, clean, and fast results, without managing browsers or infrastructure.

Why should a person choose your product over its competitors?

ScreenshotMAX's answer

Unlike other tools, ScreenshotMAX is built specifically for developers:

  • All-in-one API: Screenshots, PDFs, videos, scraping: no need for multiple services.
  • Clean by default: Blocks cookie banners, ads, and popups automatically.
  • Automation ready: Schedule recurring tasks without cron or extra setup.
  • Fast & scalable: Runs on Google Cloud with built-in CDN via Cloudflare.
  • Easy integration: Official SDKs, Swagger docs, and secure HMAC authentication.

It saves hours of dev time and delivers consistent, production-grade results.

How would you describe your primary audience?

ScreenshotMAX's answer

ScreenshotMAX is designed for developers, technical teams, and SaaS builders who need to:

  • Automate website screenshots, HTML-to-PDF generation, or web scraping.
  • Integrate rendering tasks into CI/CD, monitoring tools, or backends.
  • Save time by avoiding browser setup, Puppeteer maintenance, or infrastructure headaches.

Whether you're a solo indie hacker, a startup dev team, or a platform engineer, ScreenshotMAX helps you move fast with clean, reliable, and scalable APIs.

Which are the primary technologies used for building your product?

ScreenshotMAX's answer

  • Headless Chrome + Puppeteer: For capturing screenshots, PDFs, and videos with precision.
  • Google Cloud Platform (Cloud Run, Cloud Tasks, Datastore, Cloud Storage): Scalable backend for APIs, storage, job queues, and data.
  • Redis: Real-time rate limiting and usage tracking.
  • Cloudflare + Workers: Global CDN, DNS, and edge logic for speed and reliability.
  • Stripe: Subscription billing and customer portal.
  • Swagger / OpenAPI: For interactive and well-documented developer experience.
  • SDKs (TypeScript, Python, PHP): Easy API integration with typed interfaces and helpers.

What's the story behind your product?

ScreenshotMAX's answer

ScreenshotMAX started as a side project, built out of a real-world need.
As a freelance developer, I had to create a screenshot system for a CI/CD pipeline; automatically testing how hundreds of PDFs were rendered from HTML. Most existing tools were either unreliable, too complex, or didn’t scale.

So, I built my own.

What began as a simple internal tool quickly became something more:
An all-in-one API for screenshots, PDFs, video rendering, and scraping, designed for developers who want powerful results without managing headless browsers or servers.

ScreenshotMAX is my first SaaS product: built for fun, to learn, and to solve a problem I know developers face every day.

SockJS mentions (2)

  • WebSockets and Node.js - testing WS and SockJS by building a web app
    SockJS is a library that mimics the native WebSockets API. Additionally, it will fall back to HTTP whenever a WebSocket fails to connect, or if the browser being used doesn’t support WebSockets. Like WS, SockJS requires a server counterpart; its maintainers provide both a JavaScript client library and a Node.js server library. - Source: dev.to / about 2 years ago
  • Top WebSocket libraries for Node.js in 2022
    SockJS is a JavaScript library that provides communication between the client and the server in a way similar to the native WebSockets API. SockJS functions with a server counterpart in the form of sockjs-node and SockJS-client, a JavaScript client library. - Source: dev.to / over 3 years ago
