soumyaranajan/mongui repository overview

A lightweight, self-hosted web UI for browsing and editing MongoDB. A maintained, modern replacement for the deprecated mongo-express.

What it does

Point it at one MongoDB instance, log in, and manage your data from the browser:

• Browse databases and collections from a sidebar (with document counts)
• Query documents with filter, sort, and projection, plus server-side pagination
• Edit documents in a JSON editor, with full CRUD (insert, update, delete)
• Manage collections (create and drop, with typed confirmation)
• Read-only mode to block all writes for safe, browse-only deployments

BSON types like ObjectId, Date, and Decimal128 are preserved end to end using Extended JSON.
