Get Started View Features

Add a NoSQL database in seconds, with just one line of code.

builder.ConfigureServices((context, services) =>
{
    services.AddNetlyDB();
}

var app = builder.Build();

Easy querying (LINQ expressions)

var belgianUsers = users.Query()
    .Where(x => x.Country == "BE")
    .OrderBy(x => x.Name);

What is NetlyDB?

NetlyDB is a .NET-native NoSQL document database designed for teams that want speed now and scale later. Store strongly typed documents, flexible dynamic JSON, and binary files in dedicated file (blob) collections. It can run embedded inside an application, expose APIs, provide a Management UI, and scale toward distributed clustered deployments with replication and reconciliation.

Key features

How it works

Add NetlyDB to your application with a single line and it lives alongside your application. It is modular and you can cherry-pick and configure exactly what you need from it. It is designed to be plug and play from code, without any required installation on the system.

Key components

NetlyDB Core

NetlyDB Core coordinates all primary services used by embedded and distributed deployments.

Core services handle collection lifecycles and wire the key runtime subsystems together so higher-level modules can stay composable.

Collection coordination

Tracks schemas, typed registries, and document pipelines.

Query and index flow

Routes queries through filtering, planning, and index-backed execution.

Persistence and recovery

Connects snapshot and datalog services for durable state.

Extensible hooks

Supports replication modules and optional hosted runtime services.

Modules are easy to implement:

builder.ConfigureServices((context, services) =>
{
    services.AddNetlyDB()
    .AddNetlyDBCollection<User>() //One line to create a strongly typed collection 
    .AddNetlyDBAPI() //One line to create a self-hosted API
    .AddManagementUI() //One line to create a self-hosted management UI
    .AddNetlyDBMCP() //One line to create a self-hosted MCP Server
    .JoinCluster(); //One line to join another NetlyDB node in a distributed system
}

var app = builder.Build();

var users = app.Services.GetRequiredService<INetlyDBCollection<User>>();

users.Add(new User
{
    Name = "Alice",
    Role = "operator"
});

var operators = await users.ListAsync(x => x.Role == "operator");
Technical documentation

Code-first developer experience

users.Add(new User
{
    Name = "Alice",
    Role = "operator"
});

users.AddRange(
[
    new User { Name = "Bob", Role = "operator" },
    new User { Name = "Eve", Role = "auditor" }
]);
