Oxolan vs LocalSend vs Syncthing — the three-way office decision

Honest verdict

Three good tools, three different jobs. LocalSend: free AirDrop-style sending — perfect for occasional transfers and phones. Syncthing: free continuous folder mirroring — perfect for a technical user’s own devices. Oxolan: the paid office pick — every PC permanently visible, drag-and-drop plus remote browse, file locking, resumable large transfers, support. Ask "how often does the team move files?" — daily means the workflow tool earns its license.

Speed, with real numbers

All three avoid the cloud round-trip, which is the big win. Oxolan’s verified gigabit numbers are 60–115 MB/s with parallel connections and resume on 60 GB+ transfers; LocalSend is quick for ad-hoc sends; Syncthing’s block-level sync is efficient for keeping folders mirrored.

Pricing

Two of the three are free — try them. Oxolan’s flat per-office license (14-day trial) is for teams whose daily file movement deserves a workflow, not just a transfer. Oxolan plans run $149–$999/yr by office size (5 to 50 PCs) — see current pricing.

Frequently asked questions

Which should a small office pick?

If transfers are occasional: LocalSend, it’s free and excellent. If one technical person wants folders mirrored between their machines: Syncthing. If the whole team moves files all day and loses time to Windows sharing: Oxolan — that’s the daily-workflow case the license is for.

Can these tools coexist?

Completely. None of them interfere. A common combo: Oxolan for PC-to-PC office work, LocalSend for phone handoffs (Oxolan is desktop-only), Syncthing for a personal off-hours mirror.

Do any of them send files through the cloud?

No — all three transfer peer-to-peer. Oxolan is LAN-only by design (TLS 1.3, certificate-pinned). LocalSend is LAN-based. Syncthing is P2P and can use public relays if devices can’t connect directly — disable relays to force LAN.
