n8n/packages/@n8n/benchmark

n8n benchmarking tool

Tool for executing benchmarks against an n8n instance.

Running locally with Docker

Build the Docker image:

# Must be run in the repository root
# k6 doesn't have an arm64 build available for linux, we need to build against amd64
docker build --platform linux/amd64 -t n8n-benchmark -f packages/@n8n/benchmark/Dockerfile .

Run the image

docker run \
  -e N8N_USER_EMAIL=user@n8n.io \
  -e N8N_USER_PASSWORD=password \
  # For macos, n8n running outside docker
  -e N8N_BASE_URL=http://host.docker.internal:5678 \
  n8n-benchmark

Running locally without Docker

Requirements:

• k6
• Node.js v20 or higher

pnpm build

# Run tests against http://localhost:5678 with specified email and password
N8N_USER_EMAIL=user@n8n.io N8N_USER_PASSWORD=password ./bin/n8n-benchmark run

# If you installed k6 using brew, you might have to specify it explicitly
K6_PATH=/opt/homebrew/bin/k6 N8N_USER_EMAIL=user@n8n.io N8N_USER_PASSWORD=password ./bin/n8n-benchmark run

Running in the cloud

There's a script to run the performance tests in a cloud environment. The script provisions a cloud environment, sets up n8n in the environment, runs the tests and destroys the environment.

pnpm run-in-cloud

Configuration

The configuration options the cli accepts can be seen from config.ts

Benchmark scenarios

A benchmark scenario defines one or multiple steps to execute and measure. It consists of:

• Manifest file which describes and configures the scenario
• Any test data that is imported before the scenario is run
• A k6 script which executes the steps and receives API_BASE_URL environment variable in runtime.

Available scenarios are located in ./scenarios.
