Mobirise

Mobirise is a free, offline desktop website builder for Windows and Mac that uses Bootstrap-based blocks to create mobile-friendly sites and landing pages. You build locally and then publish anywhere. It's ideal for freelancers, small businesses, and individuals who prefer working offline or want to avoid monthly subscriptions. The core software is free, with paid extensions for advanced features.

It scores for its unique offline model, cost-effectiveness (free), and the ability to create fast, modern sites without an ongoing SaaS fee.
