If you're working with JSON data and need a lightweight, schema-based validation tool, check out PHAISTOS.

This JavaScript library lets you define flexible validation models and verify data integrity between providers and consumers. It's especially useful for large-scale platforms, data brokers, or any system where structured data exchange is critical.

PHAISTOS is part of the micro-MVC framework and works well alongside tools like FIWARE.

Give it a try if you're building or maintaining data pipelines and want a practical solution to keep your JSON clean and consistent.
