SwarmMarshal
Dead-simple file drops with no account and no cloud
SwarmSpan vs. LocalSend
Love LocalSend? Add a shared clipboard and a permanent link.
LocalSend nails the one thing it sets out to do: drop a file between two devices on the same network, no cloud, no account. SwarmSpan covers the same Mac↔PC file hop — and adds the parts a pure file-sender doesn't: one shared clipboard with history, a pair-once link that reconnects on its own, and resumable multi-GB transfers.
What LocalSend gets right.
LocalSend is open-source, cross-platform, and refreshingly simple. If all you ever need is to fling a file across the room, it's excellent and you may not need anything more.
Open-source and auditable
Runs on essentially every platform
From "send a file" to "two machines that feel like one."
The clipboard, not just files
Copy a path, a stack trace, or a screenshot on one machine and paste it on the other — with a searchable history that survives a reboot. That's the daily friction, and LocalSend doesn't touch it.
Pair once, not every time
A one-time 6-digit code, then your devices auto-discover each other on the LAN. No re-confirming a target on every transfer.
Resumable, agent-ready transfers
Interrupted multi-GB transfers resume from disk, and an optional loopback MCP bridge lets an agent move artifacts between machines.

Not either/or — plenty of people keep LocalSend for quick cross-platform drops and run SwarmSpan for the always-on Mac↔PC clipboard and handoff.
