SurveyJS is a set of four open-source JavaScript libraries that offer the benefits of a tailor-made in-house survey application, while considerably reducing the time and resources needed to deploy the system. These libraries are independent of specific server code or database requirements and seamlessly integrate with popular JavaScript frameworks, including React, Angular, Vue.js, jQuery, Knockout, and more. They are designed to communicate with any server that can handle JSON requests, ensuring compatibility with various server architectures and databases.
The product family is composed of:
- An open-source MIT-licensed rendering library that renders dynamic JSON-based forms in your web application, and collects responses.
- A self-hosted drag & drop form builder that features an integrated CSS-based theme editor and a GUI for conditional rules. It automatically generates JSON definitions (schemas) of your forms in real time.
- PDF Generator, a library that renders SurveyJS surveys and forms as PDF files in a browser;
- The Dashboard library that allows you to simplify survey data analysis with interactive and customizable charts and tables.

Gaffa is a REST API built for web scraping and browser automation, allowing developers to run real, full browsers at scale with a single API call. It removes the difficulty of managing headless browser frameworks, rotating proxies, CAPTCHA solving, and scaling infrastructure, all of which are handled automatically.
JavaScript-heavy and dynamic websites render exactly as they would for a human visitor by default. Beyond standard scraping, Gaffa supports AI-driven structured data extraction (extract data into a defined schema without writing CSS selectors), screenshot and PDF capture, infinite-scroll and form-filling automation, and clean Markdown conversion for feeding webpages directly into LLM and RAG pipelines.
A rotating residential proxy network keeps access reliable across regions, and a credit-based pricing model means teams pay only for the browser time and bandwidth they actually use. Gaffa is designed for AI engineers, data teams, and developers who want production-grade web data extraction without having to build and maintain their own infrastructure.

Storyblok
Storyblok is a Headless Content Management System that provides developers with all the flexibility they need to build reliable and fast websites whilst giving content creators with no coding skills the ability to edit content independently of the developer. Thanks to the headless approach your content can not only be used for one website, which is the case if you use a monolithic CMS like WordPress. Storyblok empowers you to use your content on iOS and Android apps, as well as any other platform of choice (IoT, smartwatch, AR/VR) through Application Programming Interfaces.
Storyblok helps your team to tell your story and manage content for every use-case: corporate websites, e-commerce, helpdesks, mobile apps, and screen displays.
Storyblok is a Headless CMS with a Visual Editor for developers, marketers & content editors.
The Problem: Managing digital content with a headless CMS can be a difficult task. Without a visual preview, editors are often lost and need instruction even for simple changes.
The Solution: Storyblok has the user experience of a page builder with a modern headless architecture behind. This gives the developer freedom and the editor a self-explaining intuitive interface.
