Datalensia came from a recurring frustration: working with large or deeply nested JSON (API responses, configs, logs) and struggling to understand the structure by reading raw text.
We built a set of visual tools to interact with JSON: - JSON visualizer - JSON comparator - Node / graph-based views
Everything runs 100% client-side: your data never leaves the browser, nothing is uploaded or stored.
The goal is not BI or analytics, but helping developers reason about complex JSON structures in a safe and private way.
This is still early and very feedback-driven. We’d love to hear: - What improvements would you make? - What feels unnecessary or missing? - Did you run into any bugs or edge cases?
Happy to answer technical questions or discuss implementation details.
