Opensource Terminal bandwidth utilization tool for Linux, macOS, Android, and Windows users and IT Professionals.

ArchiveBox is a self-hosted app that lets you preserve content from websites in a variety of formats. Without active preservation effort, everything on the internet eventually disappears or degrades. You can build your own personal archive box
Source https://github.com/ArchiveBox/ArchiveBox
Linkwarden is another good one
For personal purpose, self-hosted solutions are better choices than on cloud.
Use flask, Django, and SQL, or psql
wget, but better?
i think it does indexing as well. more than just wget.

Paperless-ngx is a communitysupported opensource document management system that transforms your physical documents into a searchable online archive so you can keep, well, less paper. It is a free and opensource app
Source https://github.com/paperless-ngx/paperless-ngx?tab=readme-ov-file
Comments:
I use it and really love it. It’s changed how I organize documents.
For physical documents, I bought a ScanSnap scanner and have it configured so that when I scan a document, it’s saved to a folder on my home server (via SMB), which paperless-ngx picks up and stores, then paperless-ai generates a title and tags for it using AI. All automated just by inserting a document and clicking one button on the scanner.
For documents where I need to keep the physical copy (like tax documents, which I need to retain for 7 years), I use stickers with QR codes and an ASN (Archive Serial Number) to automatically associate the digital copy with the physical one.
For digital documents, I can forward them to paperless-ngx via email, or just drag and drop them into the UI (or upload them via the Android app)
The latest version of paperless-ai added Rag (Retrieval-Augmented Generation) chat, which lets you ask questions in plain English (like “when did I install solar panels, and which company installed them?”) and it’ll find the answer from your documents. Works with local AI too.
Been using paperless-ngx for a few years now. It might not be glamorous but it’s a solid product and works well.

I hope they stay open source. I’ve come across a couple of good ones from 20 years ago and their transition was disappointing. Yep Knowledgetree and Alfreso
