How is this all free? There must be a catch!
Absolutely no catch to this freebie. This project is just my way of giving back to the community that I've learned so much from. If you'd like to show your appreciation however, you can follow me on my social media and let me know how much it helped you, or donate to help pay the cloud bills, or if you are a fellow developer, you can head to GitHub and contribute to the code by raising a PR.
