Monghoul

Monghoul is a MongoDB GUI for developers. It is built for working with MongoDB databases and focuses on schema-aware query building, aggregation work, result inspection, and cluster monitoring. The page describes it as a fast MongoDB GUI and says it includes a free tier and a Pro trial.

Its autocomplete pulls suggestions from actual collection schemas, including field paths, types, operators, stages, enum values, and index hints. The autocomplete also follows fields through $lookup joins, $group reshapes, $facet branches, and $replaceRoot so that suggestions remain consistent deeper in a pipeline. Monghoul also includes a visual aggregation builder with drag-and-drop pipeline construction, live preview, a $lookup form helper, undo and redo, and synchronized visual and code views. For cluster oversight, it shows live metrics, sparkline charts, connection usage, replica set health, slow query analysis, and database profiler information in one tab.

Query results can be viewed in table, tree, raw JSON, explain plan, and chart formats. The table view supports column pinning, sorting, resizing, inline editing, multi-select, and instant search. The tree view adds hierarchical document browsing with type badges, resizable columns, sticky headers, and keyboard navigation. The chart view offers eight chart types, dual axes, date aggregation, an interactive configuration wizard, and PNG export. The explain view reports performance grades from A through F, execution plan trees, index usage details, scan efficiency, and rejected plans.

The application ships with a Model Context Protocol server and 70+ MCP tools for AI assistants. Claude, Cursor, and other MCP-compatible assistants can query databases, analyze schemas, manage tabs, and drive the sidebar from a chat window. Additional built-in tools include an explain visualizer, an extended JSON converter, an ObjectId decoder, a connection string parser, a BSON size calculator, and an aggregation cheat sheet. It is offered as a 33 MB installer. Pricing listed on the site includes a free forever tier with 8 connections, autocomplete, the aggregation builder, schema analysis, and table and tree views, plus a 14-day Pro trial with no signup or card, a $9 monthly plan, a $6 monthly annual plan billed at $72 per year, and a $128 lifetime license with two years of updates.
