TL;DR Summary

Knack is best for web-based database apps like portals or directories, with a flat pricing model and visual builder.
AppSheet excels at mobile apps with offline sync and Google integration but charges per user.
Tadabase gives you the best of both: visual building, workflow automation, compliance, and flat pricing per account — not per user.

Introduction

Knack and AppSheet are both powerful no-code platforms, but they solve different problems. Knack lets you build custom databases and portals for the web, while AppSheet is more focused on mobile-first applications, especially those built from spreadsheets.

If you need flexible layout control and predictable pricing for internal tools or portals, Knack is a solid option. If you're gathering field data or automating tasks tied to Google Sheets, AppSheet may be better. But if you want full control, powerful automations, compliance, and unlimited users — Tadabase offers a compelling alternative.
