Load test any system
with a distributed cluster

Modern and flexible load testing framework for Pull and Push scenarios, designed to test any system regardless a protocol (HTTP/WebSockets/AMQP etc) or a semantic model (Pull/Push).

Technology agnostic

A fundamental feature of NBomber is that you can test any system from database to web server or message broker. Define and run your tests without any dependency on a protocol (HTTP/WebSockets/AMQP etc) or a semantic model (Pull/Push).

        var httpClient = new HttpClient();

        var scenario = Scenario.Create("http_scenario", async context =>
            var request =
                Http.CreateRequest("GET", "https://nbomber.com")
                    .WithHeader("Accept", "text/html")
                    .WithBody(new StringContent("{ some JSON }"));

            var response = await Http.Send(httpClient, request);
            return response;
            Simulation.Inject(rate: 100,
                              interval: TimeSpan.FromSeconds(1),
                              during: TimeSpan.FromMinutes(3))

        var redis = ConnectionMultiplexer.Connect("redis0:6380");
        var db = redis.GetDatabase();
        var random = new Random();

        var scenario = Scenario.Create("redis_scenario", async context =>
            var userId = random.Next(1_000);

            byte[] data = await db.StringGetAsync($"user-{userId}");

            return Response.Ok(statusCode: "ok", sizeBytes: data.Length);
            Simulation.Inject(rate: 100,
                              interval: TimeSpan.FromSeconds(1),
                              during: TimeSpan.FromMinutes(3))


Deploy anywhere

NBomber works across almost all OS environments – including major Linux distributions, Windows, Mac OS. It can also be deployed in containers such as Docker, Kubernetes and Swarm.

Continuous integration

Easy integration with your CI/CD pipeline to run your tests automatically, check assertions and catch any performance degradation.

Distributed cluster

Simulate millions of concurrent users by running your tests from the test agents cluster.

Controllability and flexibility

Simulate any real workload to cover complex cases with mixing Pull/Push scenarios, protocols (HTTP/WebSockets) and formats (XML/JSON/Protobuf).

Real time reports

Take a look at a test in real time and perform detailed results analysis to understand trends.

Pluggable integrations

Take advantage of the pluggable architecture and use integrations with test runners (Nunit/Xunit), container orchestrators (Kubernetes), data storage and visualisation (InfluxDb + Grafana).
