Cloud Torrent
Cloud Torrent, a self-hosted remote torrent client
Cloud torrent is a a self-hosted remote torrent client, written in Go (golang). You start torrents remotely, which are downloaded as sets of files on the local disk of the server, which are then retrievable or streamable via HTTP. Go is required to install from source. The provided set of core features requires large structural changes and therefore requires a complete rewrite for best results. This rewrite is in progress in the 0.9 branch though it will take quite some time. It will be capable of transfering files from and source file-system to any destination file-system. A torrent can be viewed a folder with files, just like your local disk, and Dropbox. As long as it has a concept of files and folders, it could potentially be a cloud-torrent file-system backend. During a file tranfer, one could apply different transforms against the byte stream for various effect. -

qrcp
Transfer files over wifi from your computer to your mobile device
qrcp binds a web server to the address of your Wi-Fi network interface on a random port and creates a handler for it. The default handler serves the content and exits the program when the transfer is complete. When used to receive files, qrcp serves an upload page and handles the transfer. Most QR apps can detect URLs in decoded text and act accordingly (i.e. open the decoded URL with the default browser), so when the QR code is scanned the content will begin downloading by the mobile browser. When sending multiple files at once, qrcp creates a zip archive of the files or folders you want to transfer, and deletes the zip archive once the transfer is complete. When receiving files, qrcp serves an “upload page” through which you can choose files from your mobile. The default configuration file is stored in $HOME/qrcp.json, however, you can specify the location of the config file by passing the --config flag. -

IPFS Kubo
An IPFS implementation in Go
Kubo was the first IPFS implementation and is the most widely used one today. Implementing the Interplanetary Filesystem - the Web3 standard for content-addressing, interoperable with HTTP.

Proton Mail Bridge
Proton Mail Bridge application
Proton Mail Bridge is a desktop application that runs in the background on Windows, macOS, and Linux to enable users to access their Proton Mail encrypted email accounts with traditional email clients like Outlook, Thunderbird, Apple Mail, and others via local IMAP/SMTP servers. Because standard IMAP cannot natively decrypt end-to-end encrypted messages, Bridge acts as a translator that downloads encrypted mail, decrypts it locally, and serves it to your preferred mail client over a local server, while encrypting outgoing messages before they’re sent to Proton’s servers. It provides a seamless integration layer for users who need offline support, familiar local client workflows, or tighter integration with desktop tools while preserving Proton’s zero-access encryption model. The Bridge app continues running even when its GUI is closed so that mail clients can remain connected and synchronized, and it supports automatic startup and robust credential handling via secure storage. -

Hyprspace
A Lightweight VPN Built on top of IPFS + Libp2p
A Lightweight VPN Built on top of IPFS & Libp2p. Libp2p is a networking library created by Protocol Labs that allows nodes to discover each other using a Distributed Hash Table. Paired with NAT hole punching this allows Hyprspace to create a direct encrypted tunnel between two nodes even if they're both behind firewalls. Moreover! Each node doesn't even need to know the other's ip address prior to starting up the connection. This makes Hyprspace perfect for devices that frequently migrate between locations but still require a constant virtual ip address. -

PingMe
PingMe is a CLI which provides the ability to send messages or alerts
PingMe is a personal project to satisfy my need to have alerts, most major platforms have integration to send alerts but it's not always useful, either you are stuck with one particular platform, or you have to do a lot of integrations. I needed a small utility that I could just call from my backup scripts, cron jobs, CI/CD pipelines, or from anywhere to send a message with particular information. And I can ship it everywhere with ease. Hence, the birth of PingMe. Everything is configurable via environment variables, and you can simply export the logs or messages to a variable that will be sent as a message, most of all this serves as a swiss army knife sort of tool that supports multiple platforms. -
