This API provides database persistence via localStorage/sessionStorage and, in compatible browsers, the Origin-Private FileSystem.
Local PDS - Storing your data on your machine
This project aims to store your data on your device. The current implementation uses Chrome localstorage. View the README for more details while I work on this site...

Simple data persistence for your Electron app or module - Save and load user preferences, app state, cache, etc
The local-only web
In this post, I explore the potential of the File System Access API to create local-only web experiences. I discuss how this API, combined with tools like Logseq, allows for on-device data storage outside the browser sandbox. While exciting, I also acknowledge the current limitations, such as the need to re-grant file access on refresh, the lack of a visual indicator for local-only sites, and the difficulty of preventing data exfiltration entirely. Despite these challenges, I believe this area holds significant potential and deserves further exploration.
Cross-Origin Storage API: Stop Downloading Twice
The Cross-Origin Storage API lets sites share one cached copy of a file (a JS library, font, or AI model) across origins by SHA-256 hash. Here's how it works.

Local-First Software
Experience apps that work offline, keep your data private, and sync seamlessly across your devices. Your data stays with you, not locked in the cloud.
I was looking at an older version of the software I'm yet again working on from what, 15 years ago, and I can't believe we're still mostly stuck with the same private blob storage options that can serve as user-data storage. S3-compatible storage + Dropbox was the list: github.com/icidasset/ongaku-ryoho-v1?tab…
Once again looking at bring your own user-data storage options (for my malleable software experiment this time). What do people think are some user friendly options that don't require any OAuth apps to be created on the server? ie. no Dropbox, Google Drive, One Drive & other services like that.
