Yes. The Free Plan is called the HOBBY plan.
HOBBY accounts are placed on a slower (cost-effective) server, however there is no minutes restriction. For faster processing times please choose a PAID account (typically 8X faster). Since the server is slower for the HOBBY account, file sizes are limited to 10 MB maximum. File sizes that exceed 10 MB on a HOBBY account will not be processed. Add-Ons are not available with a HOBBY account.
