Definitively, blitzjs is extremely good full-stack framework to build applications and there are a lot of things we can learn from them.

Nextless.js is different compared to blitzjs, here is the feature which aren't available in blitzjs:

- Payment integration

- Dashboard UI

- Landing Page

- Infrastructure as code

- Deploy in Serverless environment

Nextless.js focus on SaaS application and help you build your SaaS product faster.
