More Free dyno hours
Heroku accounts come with a monthly pool of free dyno hours, which you can use to run apps for free.
Additional free dyno hours can be permanently added to your account if you have a Free dyno hour coupon code.
With more free dyno hours, you’re equipped to do more learning, exploring, and (of course) building and deploying, with Heroku. There’s a lot you can do for free on Heroku.
