Local-First Web Applications: Keeping User Data on Device

For fifteen years, cloud-native architecture convinced developers that all software state must live in remote datacenters. When the internet connection drops, productivity grinds to a halt.

The Pillars of Local-First Software

• Immediate Responsiveness: All reads and writes occur against local flash storage without waiting for network round-trips.
• Complete Data Ownership: Your articles, media, and configurations live in a standalone data/blog.db file that you can copy, zip, and back up anywhere.
• Autonomous Longevity: Even if every third-party cloud provider disappeared, your CMS and publishing system would continue running indefinitely.
