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.
We invite you to explore our website and experience our comprehensive demo at no cost. This opportunity will allow you to assess the full capabilities of SurveyJS firsthand.

Okyline is an Executable Data Design (EDD) platform that transforms validation contracts into executable operational assets for enterprise data quality.
Instead of multiplying specifications, custom validators, monitoring scripts, tests, and reporting layers, Okyline relies on a single readable contract shared across validation, quality control, and operational monitoring activities.
The contract itself becomes executable and directly drives deterministic validation, advanced business invariant verification, multi-format processing, data quality gates, operational metrics, and historical quality analytics.
Okyline validates APIs, enterprise events, files, streaming payloads, LLM structured outputs, and distributed data flows while continuously producing measurable quality indicators, completeness statistics, validation traces, and error propagation insights.
Because contracts are created from annotated sample data, validation rules remain immediately understandable for developers, architects, QA teams, integration specialists, and business analysts.
The Community Edition includes the public specification, a free Java validation runtime, a Claude AI assistant for contract generation, JSON Schema transpilation support, and a free online studio for executable JSON contracts.
The Enterprise Edition extends the same contract-centric model to native validation of JSON, JSONL, XML, CSV, FIXED, and EDI flows, combined with operational quality dashboards, data quality gates, and long-term quality tracking capabilities, all without requiring databases, warehouses, or centralized infrastructure.

JSON Crack
JSON Crack is an innovative open-source application designed to transform complex data formats such as JSON, YAML, CSV, XML, and TOML into visually appealing and comprehensible graphs, thus improving data analysis and interpretation. Users can either input data manually, upload files, or share links, with the application efficiently generating a visual tree graph from the provided information. It also supports data conversion between different formats, enabling simple transitions from JSON to CSV or XML to JSON, while offering features for JSON formatting, validation, and automatic code generation for TypeScript interfaces, Golang structs, and JSON Schemas. In addition, the platform includes advanced functionalities for decoding JWTs, running JQ queries, and executing JSON Path commands. Users have the option to export their visualizations in formats like PNG, JPEG, or SVG, ensuring that they can share their insights easily. Crucially, all data processing occurs locally on the user’s device, safeguarding their privacy. This robust tool not only enhances user experience but also equips developers and data analysts with secure and efficient methods to manage their data, making it an essential asset in the realm of data handling. Ultimately, JSON Crack stands out as a comprehensive solution that caters to the diverse needs of those working with data.

SafeJSON
SafeJSON is an all-encompassing toolkit tailored for JSON management, aimed specifically at developers. It performs various functions, including parsing, comparing, and decoding JWTs, exclusively in the browser, guaranteeing that user data remains secure and is not sent to external servers.
Among its key features are a JSON formatter, a visual diff tool for JSON, a JWT decoder, a JSONPath query engine, and a validator for JSON Schema. It efficiently processes large JSON files, even those over 50MB, by leveraging Web Workers and provides additional features such as dark mode, collapsible tree views, and easy raw JSON export options.
Users can ensure their data privacy by monitoring the Chrome DevTools Network panel, confirming that no API keys, tokens, or sensitive information is transmitted from their devices. While the core functionalities are free, advanced features like the Diff tool and JWT decoding are available through SafeJSON Pro, which costs $5 monthly or $39 annually. Additionally, the entire codebase is open-source on GitHub, promoting transparency and enabling community contributions. This dedication to user privacy and ease of use positions SafeJSON as an indispensable tool for developers engaged in JSON-related tasks, fostering a secure environment for data handling.
