Affordable plans at every scale

We offer both a hosted SaaS solution and the option to run in your own datacenter. Locust Cloud is a monthly subscription priced by your needs for concurrent Virtual User's and the total number of virtual user-hours (VUh).

Technical pricing details for SaaS

Data retention

  • Aggregated data (reports and graphs) are stored for 180 days
  • Individual request logs are stored for 7 days
  • OpenTelemetry trace data can be sent to a customer-hosted Collector at no extra charge

Overhead

  • The minimum time charged for a test is 10 minutes
  • The set up time to launch load generators is not charged
  • Tests using less than 10 VU are charged as using 10
  • Every test is charged by its maximum target number of VU for the duration of the test

Compute capacity

  • Every 500 VUs in a test gets you one Locust worker (running on 1 vCPU with 2 GB RAM),  plenty for most HTTP and WebSocket tests
  • If your users do very high throughput (more than 1,000 requests/s per worker), use other protocols that are heavier for the load generator, or need to do heavy calculations in your scripts you can increase the ratio—you are then charged for 500 VU per worker
