Compare AB Handshake vs. Okyline

AB Handshake is a revolutionary solution for telecom service providers. It eliminates fraud on outbound and inbound voice traffic. Our advanced system of interaction between operators validates each call. This ensures 100% accuracy and zero false positives. The Call Registry receives the call details every time a call has been set up. Before the actual call, the validation request is sent to the terminating network. Cross-validation allows for detection of manipulation by comparing call details from different networks. Call registries require no additional investment and run on common-use hardware. The solution is installed within an operator's security perimeter. It complies with security requirements and personal data processing requirements. This is when someone gains access the PBX phone system of a business and makes international calls at the company's expense.

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.
