#Executable
{Data Design} with Okyline,
Data validation with Executable Data Contracts
What makes {Okyline} unique,
Clear and executable contracts
Okyline relies contracts by example: directly understandable by business teams, but also executable on a large scale, without additional development.
Beyond “valid or not”: actionable reports
Okyline provides detailed reports: errors, error rates, completness, trends over time that can be used by both business users and auditors.
Data Quality Gateway
Okyline acts as a data quality control gateway, isolating errors while allowing valid records to continue processing. This approach facilitates correction without interrupting flows.
Lightweight, fast, and sovereign
Okyline runs anywhere with a CLI of less than 1 MB, an embedded Java library, and a local studio without a backend—guaranteeing confidentiality and speed (tens of thousands of JSON, CSV... /second).
Simplify and unify quality control for your data flows
{ Breaking } garbage in / garbage out cycle_
Validation takes place before ingestion, where the risks are highest. Okyline checks the quality, completeness, and compliance of data in many formats—JSON, JSON Lines, CSV, fixed format, and XML. Whether individually or across millions of lines, discrepancies are immediately detected and documented, providing proof of compliance and traceability.

From {simple constraints} to complex and calculated business rules_
The Okyline language expresses both basic validations (formats, enumerations, dependencies...) and advanced business rules, including calculated formulas. This expressiveness allows functional requirements to be directly linked to execution, without recoding. Business logic remains governed and synchronized in real time.
Design, test, and validate your contracts with ease, directly on your data example
Okyline Studio is an interactive environment for creating and adjusting your data schemas and mappings. With no backend, Okyline Studio guarantees that your data remains securely with you, while every change is validated and documented in real time.
We never access your data
The studio operates without a backend: your data never leaves your workstation or network. You remain in control of your environments while ensuring compliance (GDPR, internal security).
Instant validation
Each modification to a schema or example immediately triggers validation. Errors are visible as they occur, without waiting for a test cycle.
Automatic documentation
Contracts drafted in the studio instantly produce clear documentation that can be used by both business and IT departments. Design, validation, and documentation progress together, smoothly and consistently.
