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.

Plauti is a data quality platform built natively for CRM, designed for organizations that want tight governance, strong security, and practical control over the accuracy of their customer data. Unlike solutions that move data to external servers or require separate platforms, Plauti runs entirely inside your existing CRM infrastructure, so no data leaves your system and no additional security perimeter is introduced.
For Salesforce customers, Plauti covers the end-to-end data quality lifecycle:
Prevent duplicates at the source: Real-time alerts notify users of potential duplicates as they enter records, helping sales, marketing, and service teams keep data clean from the start.
Protect against hidden duplicates: Detect duplicates created by imports, integrations, and APIs to keep inbound data streams aligned with your standards.
Remediate at scale with batch jobs: Run configurable batch processes to find, review, and merge existing duplicates across large data volumes, with full audit trails that support compliance, internal controls, and reporting.
Verify contact information: Check email addresses and phone numbers before they’re saved to reduce bounce rates, improve campaign performance, and support more reliable outreach.
All of this operates on Salesforce’s own infrastructure, using your existing permissions, roles, and security model. There is no separate user login, no data sync lag to manage, and no additional compliance gap to justify to auditors or security teams.
For Microsoft Dynamics 365, Plauti focuses on robust duplicate prevention and control. Admins can configure real-time alerts, leverage API-based detection, run batch processes, and apply cross-entity matching rules to keep accounts, contacts, and leads aligned and consolidated.
Plauti is built for CRM admins, data stewards, and operations teams who need immediate, self-service control over data quality—without waiting for developers, complex projects, or long IT ticket queues.

Postcoder – Customer Data Verification Made Simple.
Trusted by NHS, Sky, KFC, Rightmove, and over 10,000 organisations globally, Postcoder is the all-in-one API platform from Allies Computing that helps businesses collect accurate, verified customer data from the very first interaction. Rated 4.6 stars on G2 and the winner of multiple industry awards, it's the toolkit that keeps forms fast, data clean, and customer journeys completely friction-free.
Postcoder's address lookup lets customers find their address in seconds — whether they type a postcode, begin entering a street name, or search by geographic coordinates. The service draws on Royal Mail PAF, Multiple Residence data, Ordnance Survey AddressBase, and international address databases spanning 249 countries, delivering consistently high match rates both in the UK and overseas.
Beyond addresses, Postcoder packages a full suite of contact data tools into a single API integration:
- Bank account validation: Confirm sort code and account number combinations in real time, retrieve branch-level details, and establish direct debit eligibility before a payment mandate is submitted.
- Email validation: Go beyond syntax checks to assess domain health, detect disposable addresses, and score deliverability risk, keeping CRM lists and transactional inboxes reliable.
- Mobile number validation: Confirm whether a mobile is live and reachable across more than 200 countries, cutting wasted spend on undeliverable SMS communications.
- OTP verification: Add an SMS-based one-time password layer to sign-up, login, or checkout flows to protect accounts and verify identity at the point of entry.
Rather than managing multiple vendors, businesses get one integration, one dashboard, and one support team. Getting started takes minutes — a free trial is available with no payment details required, and the documentation includes ready-to-use sample code across popular languages.
