Frequently Asked Questions

about Reserved Bots

  • What's the difference between Protocol Bots and Browser Bots?

    Protocol Bots are for running protocol scripts, which are a sequence of HTTP/HTTPS requests. They're best for low-level testing of APIs and simple websites. Browser Bots automate full-featured headless Chrome browsers. They're ideal for testing complex web applications, especially those with lots of client-side JavaScript or WebSockets. Browser Bots cost more than Protocol Bots because they require more resources to run.

  • Can I have reserve Protocol Bots and Browser Bots simultaneously?

    Sure. You might have an API that you test with Protocol Bots, and a web app that you test with Browser Bots. You can make two separate reservations, and your load tests will automatically use whichever one matches the type of script you are running. When you have multiple reservations, each subscription is separate and you can upgrade, downgrade, or cancel it independently.

  • How do Reserved Bots compare to Loadster Fuel?

    Reserved Bots cost substantially less than Loadster Fuel, per bot per hour. We estimate that a typical customer saves about 40-80% monthly by testing with Reserved Bots instead of pay-as-you-go Loadster Fuel. Reservations are customizable, so you can design one with the right number of bots and for your needs.

  • Can I use Reserved Bots and Loadster Fuel together?

    Yes, but not in the same test. If you run a test beyond your reservation limits, that test will use Loadster Fuel instead. This can be a great way to save money if your testing needs are intermittent or irregular: use a reservation to cover your typical testing needs, and Loadster Fuel for the occasional larger test.

  • Can I upgrade, downgrade, or cancel my reservation?

    Reservations renew automatically at the end of each billing period, but you can upgrade or downgrade or cancel at any time. Upgrades take effect immediately, and you are only charged the pro-rated difference for the remainder of the billing period. Downgrades take effect at the end of the current billing period. Cancellations take effect immediately with no refunds, so if you need to cancel it's best to do so near the end of your billing period.
