An open source project that links phones and computers over one protocol. Files and links pass either way, phone notifications arrive on the desktop and can be answered from there, and one device can trigger a predefined command on another. Clients exist for every major platform.

A rewrite that throws out the old stack, ships as one executable and keeps the parts that matter: desktop and mobile sync, sharing links, and a deployment that fits on a page of instructions instead of a runbook.

Remote access with the trust chain kept in house: RustDesk is fully open source, works out of the box on a public relay, and lets you stand up your own relay so traffic never leaves your machine. Five platforms, encrypted sessions, free for personal use.

A browser download bar loses everything when the line drops and never fills the pipe. Free Download Manager splits a file into parallel streams, resumes where it stopped, and carries a full torrent engine in the same list.

Rent storage and the terms, the price and the location of the files all belong to somebody else. Nextcloud is the open source answer: sync, share links, permissions and version history on a machine you control, with calendar, contacts and document editing bolted on.

Drop a file in the browser, get a link that expires by time or by download count, and the key never leaves the link itself. No account, and the whole thing can be self-hosted.

An open source remote desktop built on a custom WebRTC stack with hardware video encoding: connect with a device code, transfer files both ways, share the clipboard, wake a machine from off. The open version is free for personal use; a paid tier adds privacy screen and a wall of machines.

A download manager built on an asynchronous Rust engine that measures the connection before deciding how many segments to use, covers ten protocols from plain links to peer-to-peer and encrypted streaming segments, and takes over downloads from the browser.

A download manager that takes ordinary links, file transfers and peer to peer sources in one queue, splits each file into parallel segments, and lets you pause, resume and reorder without losing progress. Free, open source, and quiet about what you download.

Remote control that runs on the browser as well as on the desktop, built on WebRTC. Share a screen, move files, operate the other machine and talk a colleague through a problem, with the connection encrypted and no client to install on the visiting side.

Syncthing keeps folders identical across machines by talking to them directly, with no server in between. Free and open source, paired by device ID, managed from a browser page — and honest about the difference between syncing and backing up.
