Why this project was needed

Working with data means constantly running into JSON files that are too big to open — an API dump, a database export, a log of NDJSON events. Every obvious tool falls over: the text editor freezes, the browser tab crashes, jq gets you a slice but not a way to browse, and “online JSON viewers” are a non-starter for anything sensitive or large. The usual workaround is writing a throwaway script just to peek at the shape of the data — which is a lot of friction for a question as simple as “what’s actually in this file?”
