I’ve made an open-source TUI application in Python called Mongo Analyser that runs right in your terminal and helps you get a clear picture of what’s inside your MongoDB databases.

Mongo Analyser is a terminal app that connects to MongoDB instances (Atlas or local), scans collections to infer field types and nested document structures, shows collection stats (document counts, indexes, and storage size), and lets you view sample documents. Instead of running db.collection.find() commands, you can use a simple text UI and even chat with an AI model (currently provided by Ollama, OpenAI, or Google) for schema explanations, query suggestions, etc.

I believe if you’re a developer, data engineer, data analyst, or anyone dealing with messy, schema-less data stored in MongoDB, this tool can help you understand what your data actually looks like and how its structure could be improved.
