Pricing FAQs
What are VU's and how are they calculated?
Virtual users are counted & billed based on your plan's VU limit and maximum allowed duration. Let's take an example: If you have a free plan (Plan allows: 100 VU's & 2 hour max. duration), and you run following test:
First example: Parallel users: 20, Duration: 10 minutes Billed VU's = Parallel users * Max. allowed duration, so in this case 20 * 1 = 20 billed VU's. The minimum time unit is based on the plan's allowed duration, so even if you run a test for 1 minute or 2 hours, it'll bill same VU's.
Second example: Parallel users: 20, Duration: 3 hours Here you're using two units of allowed time (as your plan allows 2 hours duration) So, Billed VU's = 20 * 2 = 40. Even if you run this test for 4 hours, the billed VUs would stay 40.
What are the limitations of free plan?
In free plan you get all features of paid plans but you get 100 VU per month. Unlike paid plans, in free plan at the end of the month all unused VU's will not be added to your next months credits.
