Knack and Bubble are two leading no-code platforms, but they serve very different purposes.

• Knack is purpose-built for internal tools and database-driven apps with a focus on simplicity and flat-rate pricing.

• Bubble is designed for full front-end control — ideal for public-facing apps, startups, and marketplaces.

TL;DR

• Knack is great for simple internal database apps.
