For free testing, you have a couple of choices:
1. While you’re learning about testing, you’ll want to conduct moderated tests, like we saw Steve Krug do. You will guide the users through your tasks and you’ll have the opportunity to see their screen, watch their facial expressions, and listen to what they say. You’ll also be able to record the sessions, but make sure to ask your participant’s permission first.
To do this, use a screen-sharing tool such as Zoom or Microsoft Teams.
2. You can use Maze or another tool to conduct unmoderated tests, where participants can use your prototype on their own. Maze will collect statistics and give you reports on each participant, click analysis, people’s comments, and even a Maze usability score.
This is fine if you need large numbers of participants, but you lose the opportunity to gain additional insight by speaking with testers. I recommend that while you’re learning, stick with moderated testing.
