BlowStack vs Whizlabs
BlowStack was built for one thing: passing cloud certification exams. Every piece of it was made for that one platform and fits the others: from any question you open the services and concepts behind it and the interactive lesson for it, and the practice exams, courses, services and concepts work as one. Whizlabs is a certification training catalogue: for each certification it sells practice tests, video courses, hands-on labs and a cloud sandbox as separate products.

Where each one is the better pick
Where Whizlabs is the better pick
- Often cheaper for one certification: USD 12.99 to USD 24.99 on sale for its practice tests, against USD 19.99.
- Two years of access to a course, against 3 months.
- Video courses and hands-on labs next to the practice tests, and a cloud sandbox for most certifications.
- A mobile app on Google Play.
- Subject matter experts answering questions around the clock.
Not the pick if you are preparing for several certifications, or want lessons you work through instead of videos.
Where BlowStack is the better pick
- Cheaper for several certifications: USD 19.99 for 3 months of all of them, paid once, against USD 12.99 to USD 24.99 on sale for the practice tests of each one, or a subscription from USD 33.99 a month.
- More questions: about 868 exam questions per certification against about 385.
- A practice exam simulator you shape yourself: practice mode with your own question count, time, scope and question types, instead of fixed tests.
- A modern way of learning: lessons in which you draw the architecture diagram, trace the flow and spot the flaw, instead of videos.
- Everything in one place: the services and concepts behind each question open inside the app, written for the exam.
- Repetitions: every missed question comes back until you get it right.
- A pass probability after 100 answered questions, and results by domain with the weakest marked.
Not the pick if you want video courses, or a sandbox to practice in a live AWS environment.
