Welcome to Palryn

Explore Palryn's features and find the right guide for your MongoDB workflow.

New to Palryn? Start with Your first query: connect, open a collection and explore a document. You do not need to configure a named workspace first.

What is Palryn?

Palryn is a desktop client for MongoDB. It brings connection profiles, query editors, document inspection and database tools into one workspace. Work with a single connection or keep several connections together in a named workspace.

Documents retain their BSON types, including ObjectId, dates, Decimal128, exact 64-bit integers, UUID and legacy C# UUID values. You can move between a compact table, expandable document fields and source-based workflows.

Connect and explore →Go from a MongoDB connection string to your first results. Find the right documents →Write a filter, use visual conditions, sort and page through results. Read and edit BSON →Inspect nested fields and understand when your changes are saved. Follow related data →Define references and put readable names beside stored IDs. Build a pipeline →Filter, group and transform data with a stage-by-stage workflow. Move your data →Choose JSON, CSV, collection copying or MongoDB backups.

Feature overview

Area	What you can do
Connections	Save and test standard or SRV connection profiles, with authentication, TLS and replica-set options.
Workspaces	Combine connections, filter Explorer namespaces, keep independent query tabs and compare results in two editor groups.
Queries	Use Source, Visual or Chips filters, typed BSON examples, sampled autocomplete, server sort/projection and paging.
Documents	Inspect nested data, edit values or source, rename properties, insert, duplicate and delete documents.
Relations	Map a field to another collection, preview referenced documents and display a target property beside an ID.
Database tools	Manage indexes and standard views, analyze a schema sample, read storage statistics and rename collections.
Aggregation	Edit ordered stages or a pipeline array, run a prefix, and create stages from result properties.
Data transfer	Import/export JSON and CSV, copy collections, and use MongoDB backup folders or archives.
Shell and access	Run real mongosh scripts and administer users, roles and direct privileges.
Preferences	Customize fonts, BSON colours, dates, query modes, notifications, tool paths and workspace restoration.

How to read these guides

Application menu means the three-line button at the top right of Palryn. A path such as Collection tools → Relations… means right-click the collection, open that submenu, then choose the action.

Examples use fictional shop.orders and shop.customers collections. Substitute your own database, field names and identifiers. Query examples are entered in Palryn's filter editor unless a guide explicitly says to use Shell or an import file.

The documentation describes implemented development features, rather than a roadmap. Public download availability is announced on the Palryn homepage. For common problems, use Troubleshooting.
