Load Testing from the Cloud
Find out how many dynos your app needs
Heroku makes it easy to add dynos, but how many you need?Blitz can simulate up to 5,000 virtual users. Blitz will send real HTTP requests and measure the performance of your app as perceived by your users.
Easy to get started
It’s easy to get started with Blitz. All you need is a URL. No scripting required.
Run load tests from 7 different regions to see how network latency affects your user experience.
Pay only for what you need
Since Heroku addons are billed by the second, you can activate our 1000 or 5000 plans and only pay for the time that you use!
