Okyline is an Executable Data Design (EDD) platform focused on executable validation contracts and operational data quality control.
Rather than managing separate specifications, validation code, tests, and monitoring dashboards, Okyline centralizes validation and quality supervision around a single readable executable contract acting as the operational reference for enterprise data flows.
The same contract powers deterministic validation, advanced business invariant checks, multi-format execution, data quality gates, and historical quality analytics across APIs, events, files, LLM structured outputs, and distributed operational systems.
Contracts are designed directly from annotated sample data, making validation rules immediately understandable for developers, architects, QA teams, and business analysts.
The Community Edition includes the public specification, a free Java runtime engine, a Claude AI assistant for contract generation, and an online studio supporting executable JSON validation contracts and JSON Schema transpilation.
The Enterprise Edition adds native validation for JSONL, XML, CSV, FIXED, and EDI flows together with operational quality dashboards and data quality gates, without requiring databases or centralized infrastructure.erprise Edition supports direct validation of JSON, JSONL, XML, CSV, FIXED, and EDI flows with operational quality dashboards and analytics, without databases.

SafeJSON
SafeJSON serves as a comprehensive local toolkit for JSON, specifically designed for developers. It executes all operations such as parsing, comparing, and decoding JWTs entirely within the browser, ensuring that no user data is transmitted to external servers.
Key features encompass a standard JSON formatter, a visual JSON diff tool, a JWT decoder, a JSONPath query engine, and a validator for JSON Schema. It can handle large JSON files exceeding 50MB, utilizing Web Workers for efficient processing, and also offers a dark mode, collapsible tree views, and a straightforward option for raw JSON export.
Users can confirm their privacy by checking the Chrome DevTools Network panel, as no API keys, tokens, or sensitive data leave their device. While the essential toolset is free to use, advanced capabilities like Diff and JWT decoding can be accessed through SafeJSON Pro, which is priced at $5 per month or $39 annually. Moreover, the entire codebase is open-source on GitHub, allowing for complete transparency and community audits. This commitment to privacy and accessibility makes SafeJSON a valuable asset for developers working with JSON data.
