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.

Uncover the email addresses of professionals from millions of organizations worldwide with our innovative Chrome Extension, which enables you to extract prospect emails from various social media platforms like LinkedIn, Facebook, and Twitter.

Furthermore, our application effectively cleans any email list, no matter its size, to minimize hard bounces and boost your email marketing success. Certain mail servers, referred to as ‘Catch-All’ servers, accept every incoming email, irrespective of whether the specific address exists, while alternative services validate an email's existence through server responses. Findthat employs a diverse range of data sources and requires that at least two sources confirm an email’s validity before categorizing it as legitimate. Keeping a low rate of hard bounces is vital, as mailbox providers evaluate your sender reputation based on the prevalence of invalid addresses in your campaigns.
