What Makes a “Good” Free Tier?

We use 3 key filters:

  • Usability - Can you actually ship something with the free tier?
  • Transparency - Are limits clearly documented, or hidden in footnotes?
  • Scalability - Can you grow into the product without lock-in or pain?

Free doesn’t mean low-quality. These tools are used in production - even on paid tiers - by teams around the world.
